The use of modern and archive remote sensing data for GIS monitoring of riparian ecosystems

Abstract

Association of lowland reservoirs with marsh systems at an ordinary water level amplitude of 3–5 m can increase the total flooding area 1.5–2 times. The use of remote sensing and GIS for the processing and storage of satellite and field data allows the study and monitoring of wetland ecosystems at a new information and cartographic level, as well as correcting and supplementing existing literary and cartographic data. In this work we used ERS data obtained from the modern Landsat­8 and Sentinel­2 satellites. The GIS­based analysis of changes in the studied landscapes revealed the zone of direct influence of the reservoir inland up to 3.5 km, and allowed the areas of shallow water and adjacent wetland ecosystems to be evaluated and four hydrological zones to be established.
