Experimental determination of bottom relief on the basis of studies of the lower part of the river Samara

Abstract

Experimentally determine the bottom relief on the basis of studies of the lower section of the river. Samara. To build a route for measuring depths and digitizing depths, we used the built-in Android application, Androzik. Along with measurements of depths, water turbidity and sedimentation rate were determined. About 2,000 depth points were obtained, the data was transferred to the GIS platform, resulting in a bottom relief model, the area and volume of the reservoir. Laboratory tests of water samples were conducted on a number of parameters, the most important of which is the "turbidity" for modeling the sludge formation process. In the course of expedition studies of the cross-section profiles of the reservoir-prototype, the information was obtained in the form of direct measurements of the depths in the cross-sections of the given cross sections. Digitization and processing of cartographic data (topographic maps, remote sensing images) are carried out in the appropriate sections of the dissertation research using special techniques. Measurements were made using echo-lot and GPS devices. For an approximate calculation of the volume of the low, experimental data on the distribution of the turbidity of water and the rate of sedimentation of suspended solids are used. According to the approximate method of estimating the amount of the nitrate deposited during the year in the specified zones of the reservoir - the prototype. The bottom relief was determined experimentally on the basis of studies of the lower section of the river. Samara.
