Estimation of sediment delivery ratio at sub-watershed level using revised and modified USLE

Predication of sediment delivery ratio in a small 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 ...

An Investigation on Selecting Cartographic Scales on Sediment Delivery Ratio in Jamash Watershed

Multicipality inputs of different analysis of digital data in modern methods of map processing causes the changes in results of erosion and sediment models. In this context, selecting a cartographic scale as the major input of spatial data has become a challenge issue in erosion and sediment modeling. Therefore, in this study, using topographic maps and selecting to spatial scales (1:25000 and ...

Empirical models based on the universal soil loss equation fail to predict sediment discharges from Chesapeake Bay catchments.

The Universal Soil Loss Equation (USLE) and its derivatives are widely used for identifying watersheds with a high potential for degrading stream water quality. We compared sediment yields estimated from regional application of the USLE, the automated revised RUSLE2, and five sediment delivery ratio algorithms to measured annual average sediment delivery in 78 catchments of the Chesapeake Bay w...
