River restoration is gaining significance as an approach for river system management, even in urban areas, where the flood risks and morphological imbalances are more evident. In cities, the highly modified environment and the lack of open spaces make it harder to apply the concept of river restoration in its whole extent, raising doubts about the feasibility of adopting restoration approaches for urban rivers. In some cases, the implementation of green and blue infrastructure strategies alone is not enough to support the river restoration goals so the adoption of gray infrastructure is necessary. In order to explore aspects related to the theme, this article discusses four questions proposed from a bibliometric study of urban river restoration: Is it worth restoring urban rivers? How much does it cost? If the watershed is heavily modified, can it sustain the restored fluvial spaces? How can the success of this approach be measured? Throughout the discussion, it is clear that due to cities’ complexity and the absence of available open spaces, there is no simple answer to these questions, each case being unique and deserving particular assessment. However, even when performed partially, without significant positive impacts on the natural environment, river restoration can bring several benefits to the urban environment, creating an opportunity of reintegrating the river as a valuable element of the landscape. Additionally, we propose a framework to assist managers in identifying and implementing potential river restoration actions.

Fast urban growth and climate change have intensified water-related challenges, especially in large cities considering their scale and complexity. The purpose of this work is to pose the key role of Integrated Water Resource Management for a city's sustainable development, aiming to improve social, economic, and environmental conditions. To reach this goal, the Greater Rio de Janeiro (GRJ), in Brazil, will be used as an exploratory case study to support the discussion about proposing a cause-consequence framework. The GRJ has 13.1 million inhabitants and suffers from uneven distribution of goods, services, and infrastructure throughout its territory. The method includes 1. Apply the City Blueprint Approach (CBA) to assess the current IWRM of the GRJ; 2. Compare the results with the sanitation main findings identified in the Strategic Integrated Urban Development Plan (PEDUI) of the GRJ; 3. Given the similarity of the CBA outcomes and the PEDUI sanitation diagnosis, the City Blueprint Framework is subsequently applied to assess the behavior of GRJ in 2040. By comparing the current and future GRJ's IWRM status, a cause-consequence framework is built, highlighting the potentials and opportunities of a sanitation improvement cycle that intends to balance social inequalities towards a better quality of life in developing cities.

Urbanization increases imperviousness and reduces infiltration, retention, and evapotranspiration, frequently aggravating urban flooding due to greater runoff and higher and faster discharge peaks. Effective strategies to mitigate flood risks require a better understanding of the watershed dynamics and space to reverse the negative impacts. However, often cities do not have proper data sets to feed mathematical models that would be helpful in mapping water dynamics. Attempts to reduce flood risks have been made for decades by means of structural interventions but were frequently designed within the logic of a local scale, using limited available spaces and often merely shifting flooding downstream. Therefore, assessing urban floods requires a modeling approach capable of reflecting the watershed scale, considering interactions between hydraulic structures and urban landscape, where best practices and non-structural measures aim to improve community flood resilience through the reduction of social and financial costs in the long run. This paper proposes an integrated approach to analyze low impact development (LID) practices complemented by non-structural measures in a case study in southern Italy, supported by mathematical modeling in a strategy to overcome a context of almost no available data and limited urban open spaces.

Disorganized urban growth, deforestation, and the occupation of floodplains and riverside areas significantly alter land-use patterns and social and environmental wellbeing. This work aims to present the analysis of the feasibility of the proposal for the implementation of a Payment for Environmental Services (PES) project for flood control. It is related to the recovery and conservation of areas of environmental interest in a hydrographic basin and considering the river channel as a reference and its buffer areas. For the implementation of a PES project aiming at the reduction of floods downstream through the recovery of riparian forests, including their subsequent maintenance, this work proposes a flowchart of the applicable steps, develops a formulation for the definition of payment for the service, and defines a set of measures necessary for its management. Through a case study, it was possible to simulate different scenarios for different recurrence time (RT) in the study area, and thus assess the damage caused by these different events. The innovation of this work comes from the use of PES for the control of floods, with the use of an integral formula to calculate the costs of PES and to evaluate the expected damages. The application of the Poisson distribution was used to estimate the losses for different RT events expected in 50 years, estimating the losses overtime for the scenario with the implementation of the PES project and without it. The damage when reduced or avoided becomes a useful resource for the establishment of other public policies.

Urbanisation modifies the natural hydrological cycle and aggravates floods. If the limits imposed by the natural environment are respected in the urban planning process, it is expected that the city resulting from this process will be able to coexist with floods, suffering minor damages. In this context, this work uses the concept of Low Impact Development to "go back in time", with the aid of mathematical modelling tools, identifying an earlier moment of initial development of the city of Mesquita, in Brazil, to evaluate the flooding situation at that time and compare it with the current situation, seeking to understand how the worsening process of urban floods evolved. Then, an alternative growth pattern is modelled from past to present, revising urban development guidelines to incorporate flood concerns and low impact development (LID) concepts. The main findings indicates that flood flows need space; the bottom of the valleys and the riverine areas should be preserved as open spaces to accommodate floods; and LID can help in preventing floods, but the excess of imperviousness is critical and very difficult to reverse.

The urbanization process heavily changes the natural landscape, increasing built areas and impervious rates, consequently aggravating floods and suffering from the co-related degradation. Recent initiatives regarding sustainable drainage and river restoration seek a compromise solution between cities and nature. In this context, this research examines a possible analytical framework for urban planning and design of flood control alternatives, using a multifunctional open space system that incorporates water dynamics into current and future urban solutions. This framework starts with a diagnosis of the current situation, analyzing three main aspects: urban floods and their consequences; urban plans and legal environmental constraints; and available open spaces and multifunctional opportunities. Then, a set of guidelines is proposed to articulate urban needs with environmental limits, intending to help in the design of urban flood control alternatives, while increasing environmental value and retrofitting urban vicinity. These guidelines include multi-scale solutions in the watershed context, using sustainable urban drainage concepts in multifunctional open spaces, which can also act as environmental connections and protective fluvial parks. Next, the current situation is taken as reference and a hydrodynamic mathematical model is used to map the behavior of possible scenarios developed to represent future conditions driven by the proposed guidelines. This proposal is applied in an exploratory case study in the Rio de Janeiro Metropolitan Region to validate the proposed premises. The obtained results show that a multifunctional open space system, supported by an orderly and sustainable land use, was able to reduce significantly the water levels in the main river, diminishing flooded areas and responding in a more resilient and less risky way.

The lack of open spaces in urban areas, associated with degraded river environments aggravates one of the main problems faced by cities nowadays: flood risk. This study aims to contribute to the sustainable management of cities by recognizing land as an important finite resource and emphasizing the importance of land use planning in designing resilient cities. The combination of an open space system with urban drainage solutions in multifunctional arrangements can provide a safer setting, better able to structure urban growth. This discussion is supported by an assessment framework that comprises historical analysis, mathematical modeling and estimation of the expected annual damage, in a case study applied to the Canal do Mangue (Mangue Channel) watershed in Rio de Janeiro, Brazil. Three scenarios were built to support the analyses. The first scenario refers to the current situation while the second corresponds to an official proposal of the municipal government to mitigate floods. Finally, the third scenario corresponds to a hypothetical alternative historic growth, from the start of the nineteenth century, assuming that urbanization was based on orderly land use planning, driven by the drainage network interacting with the urban open spaces as a planning structure axis. The results indicate that planning land use and urban development in advance while recognizing water dynamics and natural limitations, can produce better responses in terms of avoiding flood damages than adopting mitigation actions after development of water spaces and stressing land resources. The possible structural mitigation measures face limited space constraints. Therefore, the actions represented in Scenario 3 can configure a set of guidelines that can help growing cities to develop more sustainably.

O Brasil adotou, no final do século XIX, o sistema separador absoluto, em que a coleta de esgoto sanitário é separada da de águas pluviais, sendo destinado para tratamento. Entretanto, é comum (embora não desejado) que redes de esgoto separadas acabem sendo direcionadas para corpos d’água ou que ligações de esgoto (por deficiência na rede própria) acabem sendo lançadas na drenagem. Nestes casos, o sistema perde sua funcionalidade e o ambiente se degrada, sem nenhuma proteção. Uma possível correção desta disfunção, mais imediata, é a interceptação da rede de drenagem em tempo seco e encaminhamento para tratamento, com nível de defesa para o corpo receptor semelhante à do sistema unitário. Este trabalho propõe discutir o conceito de sistema de coleta em tempo seco, e sua aplicabilidade, no município de Arraial do Cabo, RJ, com a proposição de um projeto preliminar para o sistema, calculando e comparando a carga em DBO lançada em corpo hídrico nos cenários atual e proposto. Os resultados apresentados indicam que o projeto contribui com a redução da poluição causada pelo esgoto não tratado, garantindo serviços com qualidade aceitável, equidade, e continuidade, em um processo de transição para uma solução posterior definitiva.

Urban floods can threaten citizens’ quality of life, produce socioeconomic losses, and act as an urban degradation driver. Restoring urban rivers, however, is not simple and its results are usually limited. It would be desirable to enhance urban fluvial systems, control flood risks, and increase city resilience while improving the city itself. This work suggests that river restoration, when applied to an urban watershed, should be supported by sustainable urban drainage measures to compensate for the negative effects induced by city growth in the water cycle, in a systemic approach to the entire watershed. A methodological framework is proposed to verify this hypothesis intending to assess urban flooding projects in a wide sense. This framework uses a hydrodynamic mathematical model and a set of multicriteria indices. A case study in Dona Eugênia Watershed, in Brazil, was developed. Two different design concepts were considered: the usual drainage design and the river restoration combined with sustainable urban drainage. Both solutions were designed to completely solve the problems, leading to virtually zero flooding in the present situation; however, environmental and urban gains were greater when using the proposed combination. Besides, when testing resilience behavior, it was also shown to be more consistent over time.

The occurrence of floods poses a challenge to cities, resulting in tragedies and losses in watersheds unprepared to receive massive amounts of water. Therefore, studies to define impacts caused by successive flood events are essential to quantify long‐term losses and allow feasibility analysis of design alternatives to mitigate them. The financial losses caused by each event trigger successive recovery processes. Thus, it is important to identify areas with low resilience to guide public investment to prevent progressive degradation. This work presents a method to analyze successive flood events considering the recoverability of the region. To illustrate the method's application, two case studies were performed, in the Mangue Channel and Acari River watersheds of Rio de Janeiro, regions with different recovery capabilities, to test the method in different conditions and check the criticality level of these areas in relation to resilience gaps. The watersheds were also evaluated regarding projects designed to mitigate rainfall events with return periods of 5, 10, and 25 years. Among the results were confirmation of the efficiency of projects designed for lower recurrence intervals in mitigating successive damages, showing that more frequent events (although less critical individually) can be of great importance in flood control strategies.

Flood risk is generally composed of two parts: the probability of happening a hazardous event and its consequences. The first part is the source of risk and it is mainly given by the flooding magnitudes, although flow velocities and flooding permanence may play important roles. The second one reflects the vulnerability of the socioeconomic system exposed to flooding. Three aspects can represent vulnerability: exposure, susceptibility and value. Additionally, resilience can work to diminish vulnerability, incorporating the system responsive capacity. However, it is usual that risk assessment considers only the direct damage of flooding, tending to prioritize areas with high potential losses using an economic-based approach. This approach can exclude socioeconomically vulnerable communities from receiving proper attention and consequent investments in flooding mitigation measures. In this context, this paper presents an index to measure the Socioeconomic Recovery Capacity of urban areas prone to flooding through a multi-criteria approach, contributing to knowledge by introducing a social bias into flood risk discussion. The Flood Risk to Socioeconomic Recovery Capacity Index (Ri-SoRCI) considers the relative potential damage of flooding events, based on the capacity of the affected inhabitants to recover from losses. The Ri-SoRCI represents a socioeconomic parcel of the flood risk, through two indicators. The first represents the economic recovery capacity of an impacted region. The second indicates the region’s social vulnerability. The Ri-SoRCI was applied to the Canal do Mangue basin, in Rio de Janeiro, Brazil, supported by an environmental modeling tool able to simulate flooding phenomena with an integrated approach. The result shows the risk variation for different areas, from the socioeconomic point of view, subsidizing decision-making for public investments and allowing the construction of sustainability indicators to assess multiple scenarios. The case study validated the proposed index.

The river restoration approach brought several contributions to river basin management offering different river assessment tools, proposing quantitative methods and aggregated indexes with the aim of defining an environmental river status. However, many of the existing classification systems still use only the water quality as reference or, when considering a more complete framework, they are not easily applicable by river managers. Considering this fact, this work presents the River Classification Index (RCI), which offers a simple, fast and broad view of the environmental status of a river and can be combined with physical-chemical-biological parameters. The RCI aims to quantify the environmental quality of a watershed and support planning strategies. It is composed by the weighted product of two indicators representing the river connectivities and riverbank conditions, both normalized into a common scale between 0 and 1. Different weights can reproduce different perceptions of decision makers. The RCI was applied in two case studies, one in a heavily modified river basin, the other in a reasonably well preserved river basin, assessing the current situation and prospecting future alternative scenarios. Both watersheds are subjected to urban development and threatened by land use modifications. The obtained results were coherent with the conceptual expectations. The future scenarios considering the river restoration approach provided the best results, while the unplanned and unconscious urban growth proved to be hazardous.

River restoration is a strategy for controlling floods and restoring fluvial environmental quality. Urban river restoration is a challenge and involves a complex discussion, which needs to focus on the whole watershed and to recognize practical limits for restoration, balancing nature and city needs as much as possible. In this context, aiming to provide a practical tool to assess environmental effects in the flood control design process, the Urban River Restoration Index (URRIx) is proposed to quantify the effects of design alternatives, considering river restoration concepts in an urban watershed, giving an objective measure to help in decision making. Additionally, the URRIx can also be used to continuously monitor the river restoration successfulness over time, after a design alternative is implemented. The URRIx presents a multi-criteria formulation and ranges between 0 (the most negative result) and 1 (the most positive). A case study in the Rio de Janeiro metropolitan area (Brazil) was conducted to exemplify this discussion. The URRIx was applied to assess urban river improvement, through an integrated evaluation of flood reduction, urban revitalization, and river improvement. Outputs present a relevant space for considering urban river restoration - under given constraints - as a viable and valuable approach even in complex and fragile contexts.

In urbanized plains that are subject to flooding, the socioeconomic aspects, climate characteristics, built environment, and riverine processes exhibit bi-univocal relationships with the flood formation itself, creating a pattern of development without a predefined equilibrium state. The complexity of processes involved in flood management and the need for a comparative assessment method to hierarchise different design alternatives or planning scenarios requires practical and quantitative methods for urban diagnoses, including flood risk and resilience aspects. This paper proposes an alternative pathway to evaluate design alternatives for urban flood mitigation, assessing resilience in quantitative terms. In this way, a methodological framework is presented with which to evaluate flood resilience in urban watersheds planning, through the application of the Urban Flood Resilience Index (UFRI) and Future Scenarios Criteria (FSC). A case study illustrates the method using an urban watershed in Rio de Janeiro/Brazil. This study considered two possible design alternatives for flood control, with concentrated and distributed measures. The resilience mapping using the UFRI showed that the adoption of distributed measures could increase the areas classified as showing very high resilience by 41%, while very low resilience areas would be reduced by 87%. The FSC is able to present the integrated results of resilience variation from present and future conditions, considering, for example, climate change effects or unplanned urbanisation scenarios. The framework is able to perform comparisons between alternatives, showing the advantages associated with adopting distributed measures over the watershed, which reflected in a resilience value that was 24% higher when compared to the results obtained for the concentrated solutions scenario.

Urban flooding is still frequently treated as a direct consequence of excess rainfall, without considering the watershed as an interdependent system connected with the development of its territory. The traditional flood control approach implies in continuous corrective interventions, usually of local character, and resulting from post-events responses. This process requires increasingly large investments to implement (or retrofit) structures capable to accommodate the runoff generated by new urbanized areas. These efforts have not prevented floods from continuing to cause high damages worldwide. Thus, there is a need to change stormwater management strategies, shifting to a risk management approach, not only considering cost-benefit analysis, but also internalizing the residual risk accounting for inherent uncertainties, such as climate change and fast and uncontrolled urban growth. This paper proposes a multi-criteria index, the Urban Flood Resilience index-UFRI, to measure quantitatively urban resilience to floods, supported by a hydrodynamic mathematical model and socio-economic indicators, resulting in spatialized maps as a communicating tool. A case study of an urban watershed in Rio de Janeiro/Brazil is used to demonstrate UFRI potential.

The lack of open spaces and the intense land use occupation in flood plains makes floods in consolidated urban areas difficult to mitigate. In these areas, setting a standard pre-defined return period for projects can limit and even preclude flood mitigation actions. However, it is possible to propose flood control alternatives that are compatible with available spaces. Thus, determining how much the original risk is reduced and how significant the residual risk can be becomes the main target. In this context, a time-integrated index for risk to resistance capacity is proposed to address these questions. This index correlates the exposure of buildings and urban infrastructure to the hazard of a given flood and is then evaluated over a project horizon through a sequence of events. The proposed index is applied to the Canal do Mangue catchment, a highly urbanized watershed located in Rio de Janeiro. The results demonstrate the difficulty of designing flood mitigation measures in extremely occupied watersheds and the importance of evaluating residual risks associated with proposed projects. As an additional result, a scenario with concentrated measures is compared to another with distributed interventions, evidencing the greater coverage of the latter.

The city of Riohacha (Colombia) has a complex urban setting that, under the pressure of recurring intense rains, experiences increasing flood damage. With the aim of identifying a systemic solution to flood problems, a hydrodynamic mathematical modelling exercise was conducted. Within the modelling process, calibration and validation are two fundamental actions that must precede the use of the model. However, most of the river basins around the world lack hydrometeorological information, which is indispensable for the calibration process. This paper presents an original approach to collecting such information for the calibration process, based on interviewing inhabitants. The results of this effort were surprisingly good, when considering the kind of approximations involved in using people's answers as hard data. This encouraged us to promote it as a working solution for many other similar cases, which all suffer from lack of suitable data.

Climate change and increasing urbanization pose huge challenges in managing urban planning for a sustainable future. Intense urbanization resulting in the so-called mega cites aggravates floods by increasing the amount of impermeable surfaces and modifying flow routes. Statistics show that flood disasters are one of the most significant in terms of damages and losses. Urbanization rates are increasing rapidly and it is important to learn how to live with floods by alleviating their consequences, in the present and future. This concern points to the resilience concept. By including the concept of resilience in flood risk analysis and decision-making, urban drainage design moves towards sustainable drainage systems. This study discusses resilience in the flood risk contextWe considered three main drivers to define a quantitative measure of flood resilience: the capability of a drainage system to resist and provide its service continuously over time; the capability of an urban area to recover from flood losses; and the capability of urban systems to evacuate floodwaters and return to a functional state. Consequently, this paper describes how flood resilience can be modeled and spatialized by a multi-criteria index called Spatialized Urban Flood Resilience Index (S-FRESI). The S-FRESI composition (according to the resilience definition adopted) combines: the hazard characteristics and the system exposure and susceptibility, to represent flood resistance mapped over time; the ability for material recovery from losses caused by inundation, considering the income variable; and the functional capacity of the drainage system, represented by the flood duration. S-FRESI can be used to measure and visualize the changes in flood resilience attained by different flood control measures, as well as in future scenarios of population growth, uncontrolled urbanization or climate change. The index was tested with coherent and consistent results in the Dona Eugênia river catchment in Rio de Janeiro. Four different scenarios were formulated: (1) the current situation; (2) the current situation considering the implementation of sustainable flood control measures; (3) a future situation with the same infrastructure as today; and (4) a future situation with the considered flood control measures.

Unplanned urbanization is one of the main factors responsible for worsening flood-related problems in cities, increasing the frequency of flooding and flooding depths, consequently degrading both the natural and built environment. Considering this, the use of engineering techniques that reduce runoff and promote urban requalification are an efficient option for managing rainwater. This paper presents a case study of a flood control project using a storm water detention pond, designed to allow multiple uses of an urban space. The operation of the system is evaluated by an urban flow-cell model, known as MODCEL. This application seeks the best configuration for the layout of ‘Celso Peçanha’ Detention Basin, considering the local restrictions imposed by the City of Mesquita – Brazil, and optimized to damp storm flows resulting from rainfall events with return periods up to 50 years. The solution proposed considers the possibility of social urban space uses in flood control projects, revitalizing degraded areas and giving them multiple functions.
