Influence of geographical location on reservoir vegetation formation

Abstract

The paper provides information on the vegetation cover area on the reservoir bottom. In the growing shortage of water resources, one of the important tasks is to improve methods for estimating reservoir volume. The vegetation cover of reservoirs influences the quality of the water supply. While the bottom of some reservoirs is drained, this bottom is covered with vegetation, but this trend is not observed in all reservoirs. The Talimarjan and Charvak reservoirs were selected as study sites. As a method, spatial data were selected that were collected using GIS. The results have shown that when the Talimarjan Reservoir is impounded, a considerable part of the reservoir is covered by vegetation of different species, while the bottom of the Charvak Reservoir remains without vegetation. The intensity of eutrophication processes in the reservoir may cause excess nutrients and change the reservoir’s water quality in the near future. To prevent such a situation, reducing the number of plants in the reservoir and increasing water exchange is necessary.
