The rating curve is the relationship between the water stage and the associated discharge in a givensection of a channel. In steady flow, this relationship usually has exponential type, whereas inunsteady it flow has a looped shape. Since direct developing of actual looped rating curve by usinghydrometric methods is merely possible, steady-state rating curve is commonly used as a downstreamboun...
Index words: Reservoir sedimentation Pb-210 dating Sediment retention Cs-137 dating The singlemost important factor affecting the longevity of US dams is sedimentation, reducing and perhaps eliminating the reservoir capacity for future sediment storage and floodwave attenuation. A better understanding of the sedimentation rates and sediment dynamics is required for a better management of these ...
The phenomena of erosion, sediment transport and sedimentations have tremendously destructive effects on environment and hydraulics structures. In general, sediment transportation depends on river discharges, but the proposed equations inherited with large errors. To evaluate the suspended sediment loads and an optimized model on them, in this research, data were collected from some sub-watersh...
A Multialgorithm Approach to Land Surface Modeling of Suspended Sediment in the Colorado Front Range
A new paradigm of simulating suspended sediment load (SSL) with a Land Surface Model (LSM) is presented here. Five erosion and SSL algorithms were applied within a common LSM framework to quantify uncertainties and evaluate predictability in two steep, forested catchments (>1,000 km2). The algorithms were chosen from among widely used sediment models, including empirically based: monovariate ra...
