A successful experiment with a physical model requires necessary conditions of similarity. This study presents an experimental method with a semi-scale physical model. The model is used to monitor and verify soil conservation by check dams in a small watershed on the Loess Plateau of China. During experiments, the model-prototype ratio of geomorphic variables was kept constant under each rainfa...
Check dams play an irreplaceable role in soil and water conservation the Chinese Loess Plateau region. However, there are few analyses on connection between check downstream channel impact structural connectivity sediment interception efficiency. Based a field survey, this study classified mode channel, actual control area percentage by discharge canal dam land was used to quantitatively evalua...
The flood on March 25, 2019 in the Quran Gate of Shiraz led to heavy human and financial losses. Studies of the current condition of the 25 km2 semi-urban watershed of the mentioned area were performed using the SCS semi-distributed rainfall-runoff model. Due to the big difference in average elevation of the Quran Gate watershed with synoptic and rain gauge stations in Shiraz, the precipitation...
The Evidential Reasoning for Multi Criteria Decision Analysis (ER-MCDA) is based on a mapping process transforming a possibility distribution into a Bayesian basic belief assignment (BBA) related to a qualitative frame of discernement (FoD). Each element of the FoD is a fuzzy set. A new improved mapping method is proposed to get a final potentially non-Bayesian BBA on the FoD. We apply it to as...
