The paper presents recommendations for using the results obtained in sediment transport simulation and modeling of channel deformations in rivers. This work relates to the issues of empirical modeling of the water flow characteristics in natural riverbeds with a movable bottom (alluvial channels) which are extremely complex. The study shows that in the simulation of sediment transport and calculation of channel deformations in the rivers, it is expedient to use the calculation dependences of Chézy’s coefficient for assessing the roughness of the bottom sediment mixture, or the dependences of the form based on the field investigation data. Three models are most commonly used and based on the original formulas of Meyer-Peter and Müller (1948), Einstein (1950) and van Rijn (1984). This work deals with assessing the hydraulic resistance of the channel and improving the river sediment transport model in a simulation of riverbed transformation on the basis of previous research to verify it based on 296 field measurements on the Central-East European lowland rivers. The performed test calculations show that the modified van Rijn formula gives the best results from all the considered variants.

Hydrologic alternation of river systems is an essential factor of human activity. Cascade-dammed waters are characterized by the disturbed outflow of material from the catchment. Changes in sediment, dissolved load and nutrient balance are among the base indicators of water resource monitoring. This research was based on the use of hydrological and water quality data (1984–2017) and the Indicators of Hydrologic Alteration (IHA) method to determine the influence of river regime changes on downstream transfer continuity of sediments and nutrients in the example of the Lower Brda river cascade dams (Poland). Two types of regimes were used: hydropeaking (1984–2000) and run–of–river (2001–2017). Using the IHA method and water quality data, a qualitative and quantitative relationship were demonstrated between changes of regime operation and sediment and nutrient balance. The use of sites above and below the cascade made it possible to determine sediment, dissolved load, and nutrient trapping and removing processes. Studies have shown that changes in operation regime influenced the supply chain and continuity of sediment and nutrient transport in cascade-dammed rivers. The conducted research showed that sustainable management of sediment and nutrient in the alternated catchment helps achieve good ecological status of the water.

The commission of the Kaniv dam in 1973, as the last of the six dams on the lower Dnieper River cascade, changed the river regime completely. A description of these changes and their impact on the evolution of the fluvial anastomosing system form the aims of the study. The operation of the hydroelectric power plant (HPP) in Kaniv significantly affected the erosion and accumulation of sediment on valley floor and thus changed the fluvial system of the Dnieper River below the dam. The HPP initially operated on a hydropeaking system (until the early 1990s) and then on a run-of-river system. This study used the indicators of hydrologic alteration (IHA), the RB flashiness index, archival topographic and bathymetric maps, hydrological and sedimentological field studies, and satellite images to assess how the magnitude and duration of changes in the flow regime affected erosion and accumulation processes on the river bed and changed the pattern of channels as well as the landforms separating them. Until the commission of the dam in Kaniv, the fluvial system of the Dnieper River in its undisturbed state was a sand-bed channel but was then transformed from a braiding to an anastomosing river system. This was achieved by bars where consolidation of vegetation on fine clastic deposits created interchannel areas and islands. During the operation of the hydropeaking system, characterised by frequent artificial flows of short duration, channels became incised and narrowed. Interchannel areas were divided up into islands. Then, after the HPP switched to working a run-of-river system, the islands began to merge again into interchannel areas. This happened as a result of intensified erosion processes in both the main and the side channels. The operation of the HPP, by changing the flow regime and sedimentation processes in the river valley, modified the natural process of evolution of the fluvial system of the Dnieper River.

The Vistula River and the Oder River drain about 18% of the Baltic Sea Basin and drain 97.9% of the territory of Poland. This river basins serve as an example to show the kind of data, modelling, and analysis tools that are required for a qualitative and quantitative description of sediment dynamics. These methods are used to investigate sediment management options. First, a brief overview of the sediments types transported by Vistula and Oder and their tributaries is presented, anthropogenic impacts on sediment transport, followed by a description of the current methods of monitoring and modelling system used in this study. Lastly, the article looks at specific methods applications for sediment management tasks.

The removal of dams and reservoirs may seem to be an unforeseen and sometimes controversial step in water management. The removal of barriers may be different for each country or region, as each differs greatly in terms of politics, economy and social and cultural awareness. This paper addresses the complex problem of removing dams on rivers and their connected reservoirs. We demonstrate the scales of the changes, including their major ecological, economic, and social impacts. Arguments and approaches to this problem vary across states and regions, depending on the political system, economy and culture, as confirmed by the qualitative and quantitative intensities of the dam removal process and its global geographical variation. The results indicate that the removal of dams on rivers and their connected reservoirs applies predominantly to smaller structures (< 2.5 m). The existing examples provide an important conclusion that dams and reservoirs should be considered with regard to the interrelations between people and the environment. Decisions to deconstruct hydraulic engineering structures (or, likewise, to construct them) have to be applied with scrutiny. Furthermore, all decision-making processes have to be consistent and unified and thus developed to improve the lack of strategies currently implemented across world.

It is commonly believed that changes in the use of the catchment area have a direct impact on the quality of the water environment. Rivers with dams and reservoirs are characterized by a disturbed outflow of sediments and nutrients from the catchment area. The research was based on indicating the variation in time and space of loads of selected parameters of the water quality of the Brda River (Northern Poland) against the land cover changes based on the CORINE Land Cover (CLC) data for the 1990–2018 period. In the lower part of the Brda catchment area, there are three hydropower dams with reservoirs in the form of a cascade, whose work clearly affects the hydrological regime of the river. The analysis of the dependence of the dynamics of water quality changes on the usage of CLC was based on indicators such as sediments (suspended sediment load) and nutrients (total phosphorus load and total nitrogen load). The use of hydrological data on the Brda discharge above and below the reservoirs made it possible to calculate sediment and nutrient trapping efficiency. Linking the CLC data with the indices responsible for the mechanical denudation of the catchment area made it possible to show the strength of changes taking place in the catchment area. The results of the research do not indicate any direct correlation between land cover changes and the dynamics of the denudation process and matter transport in the Brda catchment area. As our research shows, the strong influence on the hydrological regime of the catchment points out the necessity to search for still other research methods supporting the decision-making cycle in the field of water management in the face of climate change.

Along the middle reaches of the Dnieper River in central Ukraine, braided riverbeds with many islands have developed in alluvial valleys. In the 1970s, six dams were commissioned, and respective monitoring infrastructure was installed. Riverbanks and valley floors composed of unconsolidated material have much lower bank strengths and are susceptible to fluvial erosion and bank collapse, particularly during the release of high flow volumes from hydropower dams. The regulation of the Dnieper River along a cascade of storage reservoirs caused significant changes in its active river channel and hydrological regime. In order to estimate channel stability downstream of the Kaniv reservoir, we conducted an analysis of the hydraulic conditions in terms of changes in flow velocity and propagation of waves caused by intervention water discharges from the Kaniv Hydroelectric Power Plant (HPP). In this paper, we assess the hydromorphological parameters of the studied river reach as well as the characteristics of the related erosion and deposition zones. Therefore, a monitoring framework for channel processes (MCP) downstream of the Kaniv HPP was installed. The analysis of the intervention discharge parameters was conducted based on measurements from July 2015. Channel stability was expressed by the following factors: Lohtin’s number (L), Makkaveev’s (Kc) factor of stability, and a complex index of stability (Mx) by Grishanin. This study shows that the velocity of artificial wave propagation may reach a speed of up to 74.4 km·h−1. The wave propagates for a distance of approx. 45 km within 65 min at a mean velocity of 37.4 km·h−1. The L, Kc, and Mx indicators used in this work showed that when water discharge increased (e.g., during typical peak-capacity operation), the channel becomes unstable and sediments are subject to erosion processes. The riverbed stability indicators clearly illustrate that an increase in parameter values is not dependent on the distance to the dam. The results are valuable for sustainable sediment management at catchment scale and hence, directly applicable in water management.

Reservoirs are formed through the artificial damming of a river valley. Reservoirs, among others, capture polluted load transported by the tributaries in the form of suspended and dissolved sediments and substances. Therefore, reservoirs are treated in the European Union (EU) as “artificial” or “heavily modified” surface water bodies. The reservoirs’ pollutant load depends to a large extent on the degree of anthropogenic impact in the respective river catchment area. The purpose of this paper is to assess the mutual relation between the catchment area and the reservoirs. In particular, we focus on the effects of certain land use/land cover on reservoirs’ water quality. For this study, we selected twenty Polish reservoirs for an in-depth analysis using 2018 CORINE Land Cover data. This analysis allowed the identification of the main triggering factors in terms of water quality of the respective reservoirs. Moreover, our assessment clearly shows that water quality of the analysed dam reservoirs is directly affected by the composition of land use/land cover, both of the entire total reservoir catchment areas and the directly into the reservoir draining sub-catchment areas.

The operation of dam and reservoirs is one of the main reasons for the transformation of river runoff. The change in the hydrological regime affects a number of other processes taking place in the river channel, including the transformation of its geomorphological features. The article presents the impact of the Włocławek Reservoir on the hydrological regime of the lower Vistula. The alterations of the river flow downstream of the dam in the conditions of the hydropeaking regime of hydroelectric plant operation and after its change to the run-of-river and interventional operation were characterised. It was assessed how the change in flow conditions in connection with the deficit of sediments affected the transformation of the Vistula river channel downstream of the dam. The nature and magnitude of changes in the Vistula river flow regime caused by the functioning of the “Włocławek” dam were determined using IHA (Indicators of Hydrologic Alteration) and the RVA (The Range of Variability Approach) method. It was demonstrated that the operation of the hydroelectric power plant in the hydropeaking system is the cause of a large flow alteration in respect of the frequency and duration of low- and high-flow pulses and the rate and frequency of change in the flow. The change in the manner of operation of the hydroelectric power plant affected the reduction in the degree of transformation of most features of the flow. The increase in water erosion force downstream of the dam led to the deepening and narrowing of the river channel. The presence of more resistant formations at the bottom of the river channel inhibited riverbed erosion, at the same time intensifying lateral erosion, which increased the width of the river channel. During the operation of the reservoir, the river channel downstream of the dam evolved towards the anabranching type system.

The paper presents an integrated approach for the apportionment of water and sediment sources and pathways in ungauged territories. The approach comprises various elements such as a large-scale semi-distributed hydrological and erosion model (using the SWAT tool), a statistical assessment of regular discharge data, the discrimination of runoff sources using end-member mixing analysis (EMMA), the apportionment of sediment sources using fingerprinting technique and sediment concentration and water discharge hysteresis rating curves analyses. The approach has been applied to Western Dvina River Basin (WDRB). The results discussed in the paper indicate main features of the water and sediment regime. The components of the presented framework provide a guide for detailed water and sediment studies making it an inexpensive way to develop a roadmap to understand important hydrological processes at a watershed scale.

River islands are a natural element of fluvial river systems. They are the refuge of many species of plants and animals and of unchanged ecological systems. Due to their spatial isolation, river islands are good places to observe colonization processes of both flora and fauna (biota). The goal of our research was to observe the development of soil mite communities colonizing the river island. Mite communities on river islands are dominated by eurytopic species, which are r‐strategists, reproduce parthenogenetically, and can be dispersed either passively by the wind or actively by phoresis on insects, small mammals, or birds. The main factors limiting the diversity of acarofauna on river islands are floods (and the resulting soil moisture content of the environment) and spatial isolation. The fertility of the habitat (content of humus) is of less importance. The results of our research indicate that Oribatida are the most sensitive to frequent flooding and high soil moisture, and they were the least effective in colonizing the island. Among the species resistant to the above‐mentioned limiting factors were Cheiroseius borealis, Cheiroseius bryophillus, Cheiroseius curtipes, Liochthonius lapponicus, Punctoribates punctum, Arctoseius cetratus, Parasitus beta, Ameroseius corbicula, Oribatula tibialis, Tectocepheus velatus, and representatives of Acarididae, Pygmephoridae, Stigmeidae, and Tarsonemidae.

Artificial reservoirs have an important role in water management of river systems in terms of flood control, water supply and sediment budgeting. Therefore, it is important to maximize the time of their effective functioning. Sediment budgeting mainly depends on sediment transport dynamics. This article illustrates the impact of the Koronowski Reservoir on suspended sediments transported by the Brda River. The river system and the reservoir represent a typical lowland river environment. Our research is based on hydrological and sedimentological investigations on the reservoir and the river system. Field measurements were used to create the respective hydrological and sediment budgets. Moreover, we carried out bathymetric measurements to generate present day bathymetry and to calculate the reservoir’s capacity. We assessed the silting of the reservoir following the approaches proposed by Goncarov and Stonawski. We show that the size and dynamics of suspended sediments are mainly determined by the hydrological conditions. Moreover, we illustrate that the suspended sediment measurements made with the filtration method correlate with the nephelometric results. Generally, we show that the Koronowski Reservoir is mainly filled up by suspended sediments. We further illustrate that the level of siltation estimated with the empirical formulas deviates significantly from calculations made by bathymetric measurements.

The Vistula transports large volumes of river load, with notable prevalence of bed load. Considerable flow irregularity over the course of a year creates favourable conditions for the formation of sand islands (bars) at the mid and lower river reach. As the bars remain emerged for long periods of time, they constitute resting and nesting grounds for water avifauna, particularly species of the Charadriidae and Laridae family. In consequence of regulatory works performed in the 19th century at the lower Vistula reach, the channel has been devoid of natural islands overgrown with riparian forests and the accompanying minor sand bars. In turn I observe a prevalence of low and, as far as morphology is concerned, poorly diversified alternating accumulation forms. Moreover, operation of the dam erected in the 1970s has increased water level fluctuation frequency in the channel below, thus resulting in more frequent inundation of sandbars. This is particularly adverse for water birdlife, whose habitats become flooded during the breeding season. Morphometric research paired with the analysis of hydrological data allowed us to indicate threshold water flow conditions at which sandbars become submerged. Furthermore, efforts were made to determine the number of potentially successful breading seasons in the years 1986–2015. Identifying the dates and the range of flood waves caused by the dam operation made it possible to indicate the number of complete and interrupted breeding cycles on sandbars. Most importantly, the study seeks to answers the question whether the habitat conditions at the regulated lower Vistula reach are sufficient to allow water birdlife to bread.

The paper presents the results of analyses of structural changes of the Vistula River bottom, in a section of direct influence of the bridge in Torun (Northern Poland) fitted with one pier in the form of a central island. The pier limits a free water flow by reducing the active width of the riverbed by 12%. In 2011, data on the bottom morphology was collected, i.e. before commencing bridge construction works, throughout the whole building period – 38 measurements. Specific river depth measurements are carried out with SBES and then bathymetric maps are drawn up every two months. The tests cover the active Vistula river channel of 390 – 420 metres in width, from 730+40 to 732+30 river kilometre. The paper includes the results of morphometric analyses of vertical and horizontal changes of the river bottom surrounded by the bridge piers. The seasonality of scour holes and inclination of accumulative forms (sand bars) in the relevant river reach was analysed. Morphometric analyses were performed on raster bases with GIS tools, including the Map Algebra algorithm. The obtained results shown that scour holes/pools of up to 10 metres in depth and exceeding 1200 metres in length are formed in the tested river segment. Scour holes within the pier appeared in specific periods. Constant scour holes were found at the riverbank, and the rate of their movement down the river was 0.6 to 1.3 m per day. The tests are conducted as part of a project ordered by the City of Torun titled ‘Monitoring Hydrotechniczny Inwestycji Mostowej 2011 – 2014’ (Hydrotechnical Monitoring of the Bridge Investment, period 2011 – 2014).

This paper presents research methods applied for calculation of a transported bed load of large lowland rivers. The research area consists of two measurement profiles on the Vistula River (Poland) in its lower course. The part with results shows the output of two research approaches used by the authors to determine the capacity of bed load transport. The first one concerned the presentation of own field measurements which involved testing sand bar dynamics with surveying and cartographic methods. The second approach was application of calculation methods in the form of a simple mathematic formula developed for the Vistula River by [1].

Quantitative and qualitative data on channel changes along the lower Vistula (Poland) arising from regulation works carried out in the 19th and 20th centuries and single dam construction in 1968. The lower Vistula currently does not comprise a homogeneous fluvial system. Due to human activity channel lacks its typological continuity − as a result of existing of a dam and channel regulation devices. Changes of the bed load balance are characterized in the segment from Kepa Polska to Baltic Sea during the last 180 years are discussed. Conducted research on different channel reaches (unregulated channel, strong transformation channel below dam and regulated reach) allowed to get to know different conditions of bed load transport in terms of its size, type of material and mode of transport. Studies showed that each increase in flows corresponds to a proportional increase in the mesoforms dynamics. The size of bedload movement was determined based on the dynamics of bars, their movement rate and the layer thickness of these forms. Studies showed that bedload in the unregulated section on average amounted to nearly 2.2 million tons per year, whereas in the regulated section it did not exceed 1.0 million tons per year.
