Estimation and forecasting method of water bodies overgrowth and siltation using geographic information systems on example of Kryukovskoye and Shapsugskoye reservoirs

Abstract

Abstract The article presents research on the overgrowth degree of the Shapsugskoye and Kryukovskoye reservoirs. A new estimating and predicting method for water bodies overgrowth and siltation using remote sensing data (RSD) is proposed. As a result, the overgrowth degree of the considered reservoirs was determined from the beginning of their operation to 2019: 93.2% and 47.3% for the Shapsugskoye and Kryukovskoye reservoirs, respectively. A pattern of intensive growth periods of higher aquatic plants was found, according to which a forecast of further water bodies overgrowth was obtained.
