Silt Charge of Water in the River Sluch: Dynamics on Length and in Time

Abstract

Change silt charge of water in the rivers can negatively be reflected in throughput the rivers beds, stability of coast, change of river structures, dis appearance of boggy places, etc. In work questions of variability silt charge waters in the river Sluch in time and on length of the river are considered. It is revealed that in time average and maximal silt charge waters decrease. While on length of the river change silt charge waters is shown not precise ly, similar on some increase silt charge waters to a mouth of the river. The researches led by the factorial analysis and graphic-analytical method on the basis of long-term materials of measurement of charges of water have shown that, on a part of posts average depth of water in the river grows, and on others - cyclically changes with the general tendency to reduction. Aver age speed in them, accordingly, falls and grows. Stratification of interrela tions of a silt charge with other factors on years is observed. The reasons of reduction of a silt charge are: 1) agrarian and forest meliorative actions on a catchments of the river, hydraulic engineering construction; 2) grassy bed of the river; 3) change of a climate that promotes growth of temperature of a surface of soils and grassy bed of the river. In developed natural-climatic conditions expediently application on reservoirs of the antierosion organi zation of territory of the land tenure including agrarian- forests- meliorative actions that will allow to adjust outflow of a moisture from reservoirs to lower warming up of a surface of the soils, to provide against a high water protection and it will favorably be reflected in manufacture of agricultural production.
