InDebris floods are high concentrated flow that occurs in steep mountain areas. Slit dam is one of
the structures designed for controlling these kinds of floods. A two dimensional model is proposed for
simu¬lation of debris flow in slit dam reservoirs. In this model, the finite difference MacCormack explicit
scheme is used for discretization of governing equations, and a formula is proposed for the slit dam boundary
condition. Due to the lack of observed data of debris floods in slit detention dam reservoirs, the numerical
model is compared with an experi¬mental model. The model results show that the applied scheme using
the proposed initial and boundary condition is capable to simulate the two dimensional movable hydraulic
jump in slit dam reservoirs. Finally, the com-parison of numerical results and experimental data confirms
that the numerical model is fairly capable to simulate the outflow hydrograph of slit dam. |
