Abstract: (4852 Views)
Zolachay river has an area about 960 square kilometer located in south-west of Salmas city. The evaluation of shape and drainage density of catchment area shows a dense catchment with high flood discharge and erosion potential. The texture variations and particle size growth are investigated at 84 locations in river catchment area. The particle size increases exponentially toward the river downstream. The results indicate that particle size growth is due to tributary entry and lithology changes. In overall view the river sediment particle size distribution shows bad sorting with positive skewness. It is used the trend of particle size mean and median for selecting the proper SDR method. Also the river suspension sediment loads estimated approximately 105 ton per day using the Yang method.
