“…It is crucial to make sure that no human actions are taken to accelerate "natural" rates of movement such as the planification of excessive land use changes or the intensification of the urban activities, which can affect water quality and soil erosion rates (Ayele et al, 2018;Challa et al, 2008). The major issue for river managers and environmental experts at the local scale is to understand the dominant erosion/accretion processes in order to prevent natural hazards, restrain the agricultural damage and allow for effective floodplain rehabilitation by working with the river without significant alteration of river processes (Piégay et al, 1997;Micheli et al, 2004;Güneralp et al, 2012;Lóczy et al, 2017). Therefore, to date, we consider that there is a need for studies that focus on channel planform dynamics in order to better understand the processes for the establishment of more effective river management.…”

“…In the work [Lóczy et al 2017] it was monitored the water replenishment of the oxbow lake and assessment of the water balance components. The full-scale hydrological monitoring was carried out and seepage losses were calculated, which showed that the lake, which hydrologically connected with river, could not store water for long period on the level higher than river water level.…”

Over the last twenty years, the number of projects aimed at river restoration and rehabilitation increased significantly. In the city it is impossible to provide full river restoration, but at the same time it is possible to create a comfortable natural environment both for flora and fauna and for the citizens. In our work it was assessed the possibility of the floodplain restoration by the water replenishment of the dry old riverbed during the vegetation season on the example of the river inside the city. The simulation of the current state allowed to verify the main parameters of the model with the existing observations of the water levels in the river and lake and water levels in the wells located in the park. The several models of the river -floodplain interaction were simulated: floodplain was separated from the river by the flood control dyke, the water replenishment of the lake and the old riverbed was due to seepage (current state); the connection of the floodplain with the river by the culvert and the replenishment of the lake and the old riverbed with surface river water. The simulation showed that the lake isolated from the river is filled to a depth of not more than 0.5 m, the old riverbed is filled with water only during spring floods. The water balance calculations of the lake showed that in the conditions of isolation from the river, the lake volume is significantly affected by precipitation and evaporation from the lake water surface area. The connection of the lake with the river surface water significantly reduces the impact of the vertical components of the water balance, at the same time increases the seepage losses from the lake because of the water level raising. The connection of the river with the floodplain makes it possible to replenish the old riverbed and the lake in the mean year, but in the dry years the water level in the lake does not allow to replenish the old riverbed during the vegetation season. Calculations showed that to be able to keep the constant water level in the lake and old riverbed, it is necessary to increase the water level in the lake.

“…Lu et al (2011) built an information system representing the Shuangtaizi coastal estuary wetland using 3S technology and, based on this, proposed three balanced optimal water resource allocation schemes, as well as providing technical support for wetland protection and restoration. Lóczy et al (2017) carried out ecological restoration of a floodplain lake in Hungary using artificial water replenishment. Similarly, David et al (2020) studied how to solve the problems of eutrophication and biodiversity in marshes using artificial water replenishment.…”

The degradation of wetlands has caused regional environment and climate problems in the Sanjiang Plain. To provide a reference for wetland protection and restoration, two artificial water replenishment schemes were designed and four indicators—water quantity, ammonia nitrogen, total nitrogen and total phosphorus—were chosen to analyse results simulated by an environmental fluid dynamics code model. Simulation results showed that the wetlands receive a suitable amount of water and reach a normal water elevation, and the concentration of most water quality indicators decreased. In addition, a fuzzy analytic hierarchy process was used to select the four indicators and 30 different combinations were designed. Following the fuzzy calculation, the comprehensive scores of 29 combinations showed that a scheme involving multiple replenishments is better than a scheme of a single replenishment. This study indicates that an effective method for restoring wetlands near or surrounding irrigation areas is rational allocation of water resources.
