Sediment yield estimation for watershed prioritization: a remote sensing study

Possibility Using Remote Sensing for Estimation Sediment Resources to Reservoir of Exploitation Dams

Sedimentation in reservoirs is a prerequisite for sustainable water management. The Dez dam is very important the country because of its role in electricity frequency adjustment. The main objective of this research is to identify the sources of sediment in the catchment using satellite images, GIS and hydro-geological information. For this purpose, the lab results of sediments mineralogy reveal...

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 ...

Sediment yield reduction in an agricultural watershed

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...
