Abstract

Slit-check dams have a flow regulation function under normal flow conditions as well as holding large solid (debris flow control). However, the effects of such structures on flow hydraulics have not been considered much until now. In this study, the effects of slit-check dams on the flow hydraulics were investigated experimentally and numerically. First, the check-dam blocks of different sizes were placed in an open channel and their hydraulic behavior under subcritical flow conditions was experimentally investigated. Then, the blocks used in the experiments were simulated in a three-dimensional numerical environment using Computational Fluid Dynamics (CFD) under the same flow conditions. Water surface profiles, energy dissipation ratios and velocity profiles obtained from numerical and experimental models were presented and discussed. In the verification of the numerical model, it was observed that the relative error percentage found between the models for different discharges in range of 4% and 8%. The results show that a slit-check dam composed of blocks placed in a subcritical flow causes a significant hydraulic jump in the flow. For the 0.8 of the relative block thickness (t/s), the hydraulic jump was found to be the most effective. Total energy loss reached 30%, and the maximum energy loss was obtained for t/s = 1.0 of the relative block thickness. As conclusion that slit-check dams with blocks are effective in flow regulation under flood and normal flow conditions besides holding large solid materials.
