Processes of Mirishkor channel using GIS technologies
Abstract
Abstract In this article, were studied sediments in the Mirishkor main canal. Were identified erosion processes resulting from water movement in the main canal with using GIS. Sediment layers in the canal water flow were identified as factors influencing the flow of the sediment through the ArcGIS 9.3 program. One of the main obstacles in the main canals is the analysis of the results of the deposition of suspended particles in the water at the bottom of the canals using geoinformation systems. The dependence of suspended particles in canals on water discharge and canal topography has been partially analysed. In the Mirishkor main canal area sediment washing core equal to an average of 9.2 tons per year, i.e. a potential erosion process is happening in this channel. As a result, the contribution of sediment flow in the canal water increases and causes a number of complications. According to the results, the particles in the upper part of the main channel move depending on the water discharge.
