The role of water mass dynamics in the zoning of water bodies with complex bottom orography

Abstract

The zoning of water bodies with complex orography of the bottom is an integral stage of general hydrobiological research, assessment of the ecological state and conditions for the existence of hydrobionts. The identification of specific areas with certain ecological and hydrological features within the reservoirs allows for a more rational location of the network of natural sampling stations and to obtain better detail of the biotic and abiotic elements of aquatic ecosystems than under the conditions of conducting engineering surveys based on a standard (proportional) monitoring network. The complex orography of the bottom of the water body complicates water exchange between individual areas. As a result, different biotopes are formed in different parts of the reservoir, which can be significantly different from each other.
