Debit yang mengalir melalui sluice gate dapat menghasilkan loncatan hidraulik. Hal ini disebabkan karena adanya perubahan aliran dari sub kritis menjadi super kritis. Terciptanya hidraulik menyebabkan erosi atau pengikisan dasar saluran. Maka direncanakan penambahan peredam di hilir berbentuk segitiga, trapesium, dan sinusoidal untuk mengontrol profil panjang Tujuan penelitian yaitu mempelajari...

Erosion is defined as the displacement of bottom materials due to flow energy and moving them farthest distance, which negatively affects stability hydraulic structures. In this research, effect properties screen walls on scour in open channels was studied. Therefore, study included evaluating diameters openings (φ), wall thickness (t), ratio distance from gate height opening below process. A t...

Numerical modeling of open channel ̄ows with shocks using explicit ®nite di€erence schemes is constrained by the choice of time step, which is limited by the CFL stability criteria. To overcome this limitation, in this work we introduce the application of a multiple grid algorithm to the ®eld of computational hydraulics. By coupling this algorithm to a second-order accurate MacCormack scheme, w...
