Explicit Hydraulic Modeling of Sedimentation Transients in Alluvial Channelsby Mohammad Karamouz, Polytechnic Inst of New York, Dep of, Civil & Environmental, Engineering, Brooklyn, NY, USA,
Abstract: An explicit finite difference numerical scheme is used in this study to model sediment transients in alluvial channels. The governing equations are momentum equation and continuity equation of sediment water mixture. Sedimentation transients are frequently experienced in sand-bed channels due to change in bed level or addition of a large concentration of sediment to the channel. The proposed model studies the deviation from equilibrium conditions caused by natural or man made disturbances. The stability and convergence of the numerical scheme is also investigated.
