Abstract

The water flowage in erodable surfaces causes displacement of materials on mountain slopes and river beds that is called transport or sediment bringing. The main aim of sediment transport research is finding a relationship between the amount of transported materials, hydraulic parameters and characteristics of river bed materials. These kinds of researches in the last decades are getting very interesting. In this research, by use of DISCHARGE, sediment and precipitation of the stations with at least 20 years data, the relationship of DISCHARGE and sediment in Ghare Sou drainage basin in GOLESTAN PROVINCE was considered. We used the regression method in the way of estimating sediment yield. After arrangements of data and estimating regressional relationships of DISCHARGE, sediment yield and precipitation, the amount of monthly and yearly stations were analyzed and the best choise in determining the relationship between DISCHARGE and sediment yield was selected. Also in order to analyze geologic formation, geology maps with the scale 1:10000 were digitized. Results showed that although Siysh Ab had the highest DISCHARGE amount, Ghaz Mahale hydrometer station showd the highest sediment amount and the maximum SUSPENDED LOAD in the month of Mehr. Generally the effect of precipitation is low on DISCHARGE and sediment yield of the rivers, and only recorded sediment of Ghaz Mahale gets more effects from precipitation. From geological point of view, a major part of drainage basinis formed from loess and alluvium. Sediment yield is high in some stations especially in Ghaz Mahaleh in wich the slope is relatively high. The result of the research introduces the exponential model as the best fitness in considered stations.
