STUDY OF WATERFLOW IN BIG CHANNELS USING GIS IN RELATION WITH EROSION PROCESS

This paper studied sediments on the canal. The process of erosion caused by the water flow in the main canal is determined using GIS. One of the main factors forming erosion of basic sediments in water, which the sands on the canal are sediments under the channel. Effective use of water supply for irrigation is calculated at sediment level on flow and depends on erosion process such as precipitation, field erosion and run-off. We can measure the amount of the water erosion in the country by mainly studying the water erosions in the canals. The sediments of water flow on the main canal were express erosion impact on flow by ArcGIS 9.3.
