[ 1 ] - Empirical Relation for Prediction of Sediment-Trapping Coefficient in the Experimental Flume of the Stepped Slit Check Dams
Eroded sediments from catchment areas transport by streams and deposit in downstream less steep areas. Despite reducing the useful life of various hydraulic structures including reservoir dams, flood walls, and bridges, this phenomenon changes the main river hydraulic conditions and increases the flood prone farms in the riverbank area. Check dams are among the structures that can prevent form ...
[ 2 ] - Modeling Lake Urmia Water-Level Changes using Local Linear Neuro-Fuzzy Method
According to the water resources and climate change and challenges of Urmia Lake basin, which is the discharge and final destination of North West Rivers, a model was presented. Due to climate change and water resources in river basin such as rainfall, climate change in basin that has direct impact on evaporation over water catchment areas and lake water, this model can be provided. In addition...
[ 3 ] - Parametric Evaluation of the Static Stability Analysis of the Asphaltic Concrete Core Rockfill Dams
The present study examined the effect of the geometric parameters of the Rockfill dams on the 2D static analysis of slope stability. In this regard, several numerical models analyzed for eight heights, three slopes of upstream and downstream, three vertical and skewed core thicknesses and four different impounding time stages namely, "End of Construction", "Full Reservoir", "Half Full Reservoir...
[ 4 ] - Experimental Study of the Effect of Hydraulic Parameters on Debris Flow Control in Inclined Slit Trapezoidal Check Dams
Check dams are one of the structures used to control debris flows. In this study, in order to evaluate the effect of hydraulic parameters on debris sediment trapping rate by the slit trapezoidal check dams with different angles, and to develop an empirical relation for determination of trapping coefficient of the dam reservoirs, three physical models of the check dams were used. The tests were ...
