FILTRATION CALCULATIONS OF THE EARTH DAM OF THE YUMAGUZINSKY HYDROELECTRIC COMPLEX

The purpose of the work is to substantiate the methodology for monitoring the erosion state of the coastal zone of water bodies using remote sensing data and to propose coastal protection measures that ensure anti-erosion protection. To monitor the development of coastal erosion, a methodology is proposed based on the construction of a topographic relief map and calculations of the water WRI and vegetation NDVI indices obtained from the analysis of remote sensing data. The WRI index map, combined with a topographic map of the area, allows you to determine the direction of runoff, and the vegetation index NDVI allows you to characterize the stability of slopes by assessing the density of vegetation development. When analyzing two maps, erosion areas can be identifi ed. The algorithm for monitoring the development of coastal erosion based on the results of satellite imagery processing was tested during the formation of the Konakovo-Agrotourism tourist cluster. The erosion areas identifi ed on the constructed maps are confirmed by the results of in-kind observations and photo recording of the state of the banks of the Volga River in the Konakovo District of the Russian Federation.
