APPLICATION OF SURFACE EROSION MODEL TO ESTIMATING SEDIMENT YIELD IN JIALINGJIANG WATERSHED UPSTREAM OF CHANGJIAN WATERSHED, CHINA

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 ...

Geographic information system and process-based modeling of soil erosion and sediment yield in agricultural watershed

BACKGROUND AND OBJECTIVES: The study explored the capability of the geographic information system interface for the water erosion prediction project, a process-based model, to predict and visualize the specific location of soil erosion and sediment yield from the agricultural watershed of Taganibong. METHODS: The method involved the preparation of the fou...

Sediment yield reduction in an agricultural watershed

Contribution of stream channel erosion to sediment yield from an urbanizing watershed

Stream channel erosion has long been suspected as the major contributor to long-term sediment yield from urbanizing watersheds. For San Diego Creek in southern California, measurements from 1983 to 1993 showed that stream channel erosion furnished 10(5) megagrams per year of sediment, or about two-thirds of the total sediment yield. Thus, because channel erosion can be a major source of sedimen...

Evaluation of soil erosion and sediment yield estimation various empirical model by observation values (Case study: Babolroud watershed, Mazandaran Provienc)

In this study where done in Babolroud basin, seven models include MPSIAC, EPM, Fournier, Douglas, Kirkby, Geomorphology and Hydrophysical was evaluated to determine the best model  for estimation of soil erosion and sediment yield. These models have not been compared together as integrated in the previous researches. The zoning soil erosion intensity map was prepared for each model using GIS. T...
