Uncertainties in Evaluation of the Sediment Transport Rates in Typical Coarse-Bed Rivers in Iran
Flow and sediment transport processes are different and more complex in coarse-bed rivers than in sand-bed rivers. The main goal of the present study is to evaluate different modes of sediment transport using different hydrometric and hydraulic methods, and to address the major uncertainties. Four river reaches were selected as representatives of coarse-bed rivers in the Northwest of Iran. A se...
متن کاملRelationship between Hydromorphological and Ecohydraulic Characteristics Flow Regime to Habitat Suitability Capoeta gracilis (Keyserling, 1861): Understanding Habitat–Population Dynamics Fishes and Ecological Flow Scenarios of Zarrin-Gol River
Investigation of ecological, hydrological status and habitat Suitability of river is one of the key elements in river ecosystem management. In this regard, in the present study, in order to evaluate the ecological sustainable conditions in Zarrin-Gol River of Golestan Province, during stepwise calculations, echo-hydraulic and hydromorphocological analysis of the habitat of Capoeta gracilis (Ke...
متن کاملExploring accuracy of statistical characterization of gravel beds using Kinect device in the laboratory scale
Mountainous river beds-generally consist of gravel particles that the precise description of such bed is not only important hydraulically, but also it has great environmental significance. The accurate estimation of bed roughness gives us valuable information to make reliable hydraulic models of flow in river with rigorous bed form. This study discuses about the accuracy of the Kinect device in...
متن کاملInvestigating the Banks Sensitive to Erosion with an Emphasis on Geological, Geometric, and Hydraulic Characteristics: A Case Study of Bashar River
Extended abstract Introduction The vital need for river management is understood and predicts bank erosion processes. River bank erosion is one of the sediment major sources for many rivers across the world. Bank erosion is a key process in fluvial dynamics, affecting a wide range of physical, ecological and socio-economic issues in the fluvial environment. These include the establishm...
متن کاملSensitivity analysis of geometric and hydraulic parameters on water depth of flood plain in the AbNik River
Transfer of debris flow caused by floods in the river downstream of the mountains leads to several damages every year. Numerous researches have been carried out on the Mountain Rivers the results of which show the importance of performing more researches to control debris flows in the floodplain because of various effective hydraulic-geometric parameters.For this purpose, AbNik Mountain River l...
