Abstract: Because of hydraulic sorting (selective transport of grains by the flow), bed‐load transport of mixtures of sand and gravel in streams is difficult to predict. The transported gradation is generally different from the ...

Abstract: To facilitate administrators’ abilities to handle reservoir operations, factors on how muddy water was formed inside the reservoir should be identified. According to field observation data, during typhoon events, there ...

Abstract: A horizontal two-dimensional mobile bed model for simulating the formation of river-dominated deltas in the river mouth or reservoir is presented, which is composed of shallow water equations, sediment transport formula, ...

Abstract: For investigating selective withdrawal problems, laboratory experiments were conducted in a horizontal flume with a co-directional two-layer flow of different density into a line sink. Saline water was used as the fluid ...

Abstract: The Richard’s equation was used to numerically model 1D flow within unsaturated topsoil and solved using a two-step Crank-Nicolson scheme. Under constant water supply, the Darcy velocity obtained at the upper boundary, the ...

Abstract: Movable bed experiments from a flume into a basin were conducted to study the development of alluvial deltas. The experimental setup was aimed at the bed-load mode. Results showed that the development of the delta can be ...
