Different approaches to estimate the sediment yield in a tropical watershed

Using a special empirical model to estimate sediment yield of Koohbord dam watershed in Kohgilouyeh County

Extended abstract Koohbord dam watershed with a total area of 38.29 square kilometers in Kohgiluyeh and Boyerahmad province is one of the watersheds without sedimentation data, which requires the use of empirical models to estimate the sediment for estimating sediment, so the results obtained through data is the basis of the management plans of dam watershed. In this research, using base maps ...

Sediment yield reduction in an agricultural watershed

Regional estimation of sediment yield using monthly sediment rating curve in Qarasu watershed

This study was aimed at identification and determination the spatial variations of sediment yield in Qarasu watershed located in Ardebil province, NW Iran, considering the negative consequences of erosion and sediment yield. In this regard, the monthly time scale, as the basis of work, was used to prepare the sediment rating curves. Preparation of monthly sediment rating curves based on sample ...

Runoff and sediment yield modeling using WEPP in a semi-arid environment (Case study: Orazan Watershed)

Water erosion is a major environmental problem in many parts of the world. Majority of semi-arid countries are concerned because of their specific climate and soils sensitivity, but also because of the recent intensification of human activities and agricultural practices. Accurate estimation of water erosion for various land-use and climate scenarios is so an important key to define sustainable...

Comparing WEPP and Hydro Physical Models to Estimate Soil Erosion and Sediment Production: A Case Study of Chardavol Watershed

Extended abstract 1- Introduction Soil erosion and sediment production include fundamental limitations in the use of soil and water resources. The sediment yields watersheds in addition to the loss of soil fertility, causing water quality reduction. Therefore, evaluation processes that govern their behavior to better understand and assess the systems of watershed management practices are imp...
