Method of restorating water level of small rivers

“…The main reason for the degradation of small rivers is the deposition of sediments in the channels due to the irrational use of water resources, economic activities on the banks of rivers, which include plowing the soil of the water protection zone, unauthorized discharges of untreated runoff from adjacent territories, etc. The degree of river degradation depends on the volume of sediment layers in the channel and is manifested by a rise in the water level during the passage of high water [12,13]. When assessing the volume of sediments, normal retaining level NRL in the river is established.…”

“…Anthropogenic factors causing flooding of floodplain lands include: regulation of river flow, development of land reclamation, leveling of the soil surface, passages of heavy agricultural machinery, irrational planting of forests' bands, construction of roads and canals in the embankment without taking into account the terrain, crossings on beams, terracing of slopes, plowing across the direction of the natural runoff of atmospheric precipitation [11]. Natural and anthropogenic factors, acting on the agrolandscapes of the steppe river basins, accelerate the processes of soil erosion, which leads to an intense washoff of fine earth into river beds and baulks [12]. As a result, degradation of watercourses occurs, which causes change in the natural coastline, occurrence of emergency situations associated with floods [1,13].…”
