The European Commission highlighted that in Spain: “there is a lack of adequate incentives for efficient use of the resource and the adequate contribution to the recovery from different users is not guaranteed” and recommended to “present transparently subsidies and cross-subsidies”. This paper develops a robust hydro-economic methodological approach that provides transparency in the water cost contribution calculations and helps to assess the economic efficiency of the water resources allocation strategy for a particular water system. The Upper Genil River (a sub-basin of the Guadalquivir River Basin in southern Spain) presents an interesting context of study given its intricate multi-source supply system to meet multi-sectorial water demands, along with conflicts (especially during critical drought events) over historical water rights and the priority of water use. The simulation results demonstrated that, despite the additional average annual cost paid by the household water user for having the theoretical priority of water use (€ 6863 per cubic hectometre of water consumed) compared to the agricultural water user, in practice, that extra cost does not translate into a significant increase in the guarantee of water supply. In fact, the priority of water use would only be patent in very extreme drought events (200-year return period) and when all alternative water supply sources are exhausted. Therefore, competent authorities should ensure that a greater emphasis is placed on transparent water cost recovery assessments to achieve sound water pricing policies and efficient water allocation strategies, which can help to successfully address the major challenge of water scarcity.

Droughts and water scarcity events are predicted to be more frequent and intense in the future, especially in Mediterranean countries. However, are the most recent drought management plans (DMPs) built on the latest technical, engineering, and scientific knowledge, as well as the learning experiences from managing historical droughts? The most significant challenge that surfaces, when a new drought event strikes, is the difficulty in predicting its duration (which can vary from months to years), the severity (or degree of affection to water resources), and the potential environmental, economic, and social impacts. Hence, there is an importance of integrating reliable forecasting and modeling tools in the development of modern DMPs, so the potential risk can be assessed under a range of possible drought scenarios. This will ensure that the proposed measures and actions of the DMP are sufficiently robust and proportionate to the drought and water scarcity situation. This paper provides a critical assessment of the core technical concepts and principles to be taken into consideration when developing the methodological and operational framework of a DMP. The case of study chosen is the Guadalquivir River Basin in southern Spain, which presents one of the most complex and paradigmatic cases in this regard. This region suffers recurrent episodes of drought and water scarcity, together with fierce competition among water users. Recently, a new strategic DMP has been approved and adopted in December 2018. The implications of applying the DMP in practice during the drought have been also evaluated. This study draws important lessons learned that could be applied in other areas suffering from water scarcity and droughts.

In an ever-growing environment of uncertainty, complex interactions and climate extremes, the effective implementation of Public Participation (PP) into water management is sought as a key step to address water challenges and achieve holistic solutions. This requirement was already set out in the EU Water Framework Directive (Art. 14) 20 years ago. However, is PP successfully implemented in water management decisions, practices and policies nowadays? The literature review has revealed that there are few recent and detailed studies that assess this issue at the river basin scale. The aim of this paper is to contribute towards building evidence base on this topic. The learnings could be applied during the current consultation and development of the 3rd cycle River Basin Management Plans across EU. This study presents the complex and paradigmatic case of the Guadalquivir River Basin (GRB) in southern Spain. This work evaluates the real influence of PP on the most recent (2018) GRB Drought Management Plan (DMP) and draws important conclusions and recommendations in this regard. The findings showed that PP had, actually, negligible influence on shaping the final (2018) GRB DMP. In fact, there was a very limited incorporation of the local knowledge and experience received from participants, highlighting the absence of a truly inclusive participation strategy. In contrast to this, PP should proactively involve all interested parties at an early stage when there are still opportunities to alter the strategy. This could bring significant benefits such as taking more ownership and responsibility by water users.

Climate change is anticipated to exacerbate the frequency, the intensity, and the duration of droughts, especially in Mediterranean countries. This might lead to more serious water scarcity episodes and fierce competition among water users. Are we really prepared to deal efficiently with droughts and water scarcity events? This paper sheds light on this question by reviewing the evolution of European drought management planning policy, recently developed scientific and technical advances, technical guidance documents, and an extensive number of journal papers. More specifically, Spain presents an ideal context to assess how drought risk has been historically addressed because this country has periodically suffered the impacts of intense droughts and water scarcity episodes, and has developed a long track record in water legislation, hydrological planning, and drought risk management strategies. The most recent Drought Management Plans (DMPs) were approved in December 2018. These include an innovative common diagnosis system that distinguishes droughts and water scarcity situations in terms of indicators, triggers, phases, and actions. We can conclude that DMP should be a live and active document able to integrate updated knowledge. The DMP needs also to set out a clear strategy in terms of water use priorities, drought monitoring systems, and measures in each river basin in order to avoid generalist approaches and possible misinterpretation of the DMP that could lead to increase existing and future conflicts.

Accurately forecasting streamflow values is essential to achieve an efficient, integrated water resources management strategy and to provide consistent support to water decision-makers. We present a simple, low-cost, and robust approach for forecasting monthly and yearly streamflows during the current hydrological year, which is applicable to headwater catchments. The procedure innovatively combines the use of well-known regression analysis techniques, the two-parameter Gamma continuous cumulative probability distribution function and the Monte Carlo method. Several model performance statistics metrics (including the Coefficient of Determination R2; the Root-Mean-Square Error RMSE; the Mean Absolute Error MAE; the Index of Agreement IOA; the Mean Absolute Percent Error MAPE; the Coefficient of Nash-Sutcliffe Efficiency NSE; and the Inclusion Coefficient IC) were used and the results showed good levels of accuracy (improving as the number of observed months increases). The model forecast outputs are the mean monthly and yearly streamflows along with the 10th and 90th percentiles. The methodology has been successfully applied to two headwater reservoirs within the Guadalquivir River Basin in southern Spain, achieving an accuracy of 92% and 80% in March 2017. These risk-based predictions are of great value, especially before the intensive irrigation campaign starts in the middle of the hydrological year, when Water Authorities have to ensure that the right decision is made on how to best allocate the available water volume between the different water users and environmental needs.

At the Negratín Dam (southern Spain) two main springs derived from the water reservoir were detected on the west side of the mountain ridge, matching the location of the left abutment of the dam. The seepages appear when the level of the stored water exceeds 622 m above sea level (m a.s.l.), where some paleochannels are embedded in the silts. The water level was at 631 m a.s.l. on the day of the measurements (13/12/23), close to the historical maximum (633.78 m a.s.l.). Although the water crossing the leaks does not drag particles nowadays, this sector may potentially cause internal erosion or piping phenomena implying a loss of water resources and slope instability problems. The infiltration areas were evaluated by electrical resistivity and induced polarization methods, measured along one profile on the mountain ridge between the water reservoir and the springs. We determine that the infiltrations zones are characterized by low resistivity and high chargeability distributed in small areas. We demonstrate that these methods are a reliable tool to detect and characterize infiltration zones, and they are the first step to planning mitigation actions to avoid the piping phenomena.

In recent years, due to the rise in petroleum prices and greenhouse gas emissions, renewable energy has been recommended as a power source for different types of facilities. For the period 2010 to 2020 the European Commission has established three key objectives related to climatic change and energy sustainability, such as reductions of CO2 emissions, increases in the use of renewable energy, and improvements in energy efficiency. A key industry is olive oil production in olive mills, where there is a great opportunity to reduce electricity consumption, increase additional profits related to the reduction of technologies that are harmful to the environment, and to cut back maintenance costs. For this reason, a feasibility study of grid-connected photovoltaics (PV) systems has been carried out for different types of olive mills in Andalusia (southern Spain). This region is highly energy dependent, but has an abundance of “green” resources to be exploited. The results of this study contemplate a reduction in spending on electrical power of between 2% and 37%, and an increase in the use of renewable energy of between 2% and 26%. These results are according to the self-consumption or net metering policy and the production capacity of olive oil.

This paper describes a new method for predicting trihalomethanes (THMs) presence in networks of water supply systems, using a low-cost device that permits a fast monitoring of concentrations without need of complex analysis made in laboratories. This method, based on statistical models, allows the estimation of THM concentration by monitoring parameters whose determination is direct and easy, and therefore, THM presence can be carried out in real-time. These parameters values are introduced in a multiple regression model resulting in the concentration of THMs levels. This model has taken into account parameters compulsory in water quality analysis and it has been shown that six parameters are enough to determine accurately THM concentration. In addition, the feasibility of a low-cost device that directly gives THM concentration is demonstrated. This device can be easily designed to be transported to different points of the water supply network where it is intended to make control campaigns.

This article analyses the relation between wastewater quality parameters and particle size distribution (PSD) in three real wastewater treatment plants with different biofilm technologies: submerged biofilter system, trickling filter system, and rotating biological contactor system. The main quality parameters, (suspended solids, turbidity and COD), and PSD in the influent and effluent water of each different biofilm treatment were analyzed during 1 year. The PSD was fitted using the power law (n(dp) = ∂N(dp)/∂dp = A·dp−b·Log(dp)) obtaining the coefficients A and b to define the particle distribution. Mathematical correlations between this coefficients and the rest of parameters studied were found (SS = 0.0713·A0.585, turbidity = 4.549 × 10−4·A1.096, COD = 0.0201·A0.774). The relation with the average particle size by mass was also found, (dpma = 60.3137·b−2.242). Moreover a relation between PSD and the particle elimination efficiency of the secondary treatment was study, (η = 2.844–2.498·brelative + 0.0863·Arelative). These expressions are very useful to understand the behavior of the biofilm treatment system using PSD analyses.
