Simulation of water flow management by the flood control facilities in the adjacent river basins

Abstract

A systematic approach to reducing the risk of flooding is considered. The main idea of it is to switch from the flood control only by the one hydro system on the main river but to control the whole river system, including many adjacent river basins at various levels. This proposal expands the possibility of using a flood control system of self-regulating hydro systems distributed on adjacent drainage basins at multiple levels by organizing their joint work, ensuring that the maximum allowable water flow in the control sections of the river system is not exceeded. Using the proposed approach will allow protecting from flooding significant areas of land in the lower pool of the main hydroelectric complex in the context of climate change.

Monitoring the water quality in our rivers in urban areas

“…At these points or in the immediate vicinity of them, sampling was carried out and their composition was studied. For the study of water samples, various instruments were used in a stationary laboratory [30,31,33,36,43,[45][46][47][48].…”

“…Rivers and reservoirs located in urban areas and suburbs of megacities are exposed to the strongest impact [1,4,20,[26][27][28][29][30][31]. Intensive agricultural activity near megacities creates additional environmental problems [32][33][34][35][36][37]. During the flood period, chemical fertilizers enter the water and are washed off the fields into small rivers and lakes.…”

Assessment of the level of soil pollution of agricultural lands Kotlin Island

“…The greatest danger among contaminants is represented by heavy metals, which have a very long decay period [23-27, 39, 42-45]. Small towns located near megacities, near which agriculture is carried out, are very susceptible to such pollution [23,29,36,[46][47][48]. To solve these problems, these processes require constant study.…”

Restoration of surface soil contamination density to radionuclides at according to aerial photography

“…To serve large volumes of industry, the needs of the city and agricultural enterprises, more and more energy is required [1,5,6,[8][9][10][11][12][13][14]. This leads to an increase in its production at various stations [12,[15][16][17][18]. The number of emissions into the environment is increasing, which are often not controlled [9,12,13,[19][20][21][22][23][24].…”

“…The number of emissions into the environment is increasing, which are often not controlled [9,12,13,[19][20][21][22][23][24]. Soil and water bodies are constantly polluted [7,8,12,[15][16][17][18][19][25][26][27][28][29]. With such a large load, the ecological system can hardly cope with the processing of many contaminants [28][29][30][31][32][33][34].…”
