Abstract
This article deals with the problem of the influence of surface waters of lakes on the formation of the total water flow into the quarry, designed for the extraction of solid minerals. Considerable attention is paid to the method of studying lakes by means of hydrographic survey of topography and bottom structure by mobile multibeam echo sounder in order to obtain initial data for calculations of morphometric parameters of the reservoir. The features of data processing and construction of three-dimensional models of the lake and maps of bottom sediments with the use of various software systems are described. According to the results of the analysis of the data obtained, the dependence of the value of water filtration into the quarry through rocks composing the bottom of the lake on the morphometric parameters of the lake basin, the type and power of bottom sediments.
