These particles settle in the beds and on the banks of the rivers\u0000during displacement and collects complex chemical compounds. particles that are\u0000equal to or smaller than 0.02 mm in size have good adsorption capacity. but as a result of further hydraulic and hydro-chemical impacts, these particles desorbs and\u0000pollute water for the second time. In Germany, the content of bottom sediments is\u0000examined every 3 to 5 years during monitoring of the studies of river water. During\u0000the monitoring, samples of bottom sediment taken from different spots of the river\u0000are analyzed and based on the results of these analyses, polluted parts of the river\u0000are determined. Comparison of measured value of the elements with the norms accepted is made to determine which part of the river is polluted. Classification is provided based on the pollution degree of the bottom sediments.\u0000Adsorption of salts and organic substances by the bottom sediments shows the\u0000adsorption capacity of the bottom sediments.

The article is dedicated to the determination of the wash depth of mountain rivers in floods and overflows.

Therefore, the\u0000protection of the equipment against the destructive damage of the floods and overflows should be ensured. To this aim, first of all, the depth of the fortification of the\u0000equipment basement in riverbeds and the width through which the river can flow\u0000should be determined and the works of installing coast guards should be accordingly\u0000implemented.\u0000Since the flow regime of rivers due to floods in the course of mountain riverbeds\u0000dramatically changes, the width, depth, roughness and cross-sectional area of the\u0000riverbed also changes.
