CALCULATION OF SEDIMENT YIELD IN THE S2-1 WATERSHED OF THE SHIRINDAREH RIVER BASIN, IRAN

Abstract

[...]outflow is the most important element of the hydrological cycle and that is why it is important to determine it as accurately as possible by measuring and predicting. [...]the IntErO (Intensity of Erossion and Outflow) model based on the EPM (Erosion Potential Method) method was used for calculation of outflow and sediment yield in the S2-1 watershed of Shirindareh River Basin in the Northeast Iran with the area of 46.77 km2. According to the previous studies and topographic characteristics, the river basin watershed belongs to the V category and has very weak erosion. According to the analysis, the main portion of the river basin is totally under mountain pastures (55.78%). According to the findings, it can be concluded that there is a possibility for large flood waves to appear in the studied S2-1 river basin.
