چکیده مقاله
Gabion porous weirs are of environment friendly structures that are made from local materials and have least negative impact on rivers In this study a 3D CFD code was utilized to simulate flow patterns about 6 types of Triangular porous weirs with various upstream downstream slopes in 6 discharges run the gamut from 3 to 30 liters per second The porosity of all weirs was constant and equal to 50% and also assumed to be made of spherical particles Simulation results comprise flow surface profile; velocity distribution around weirs, the ratio of through to overall flow discharge and vortex areas is presented Results indicate that the weir with upstream slope of 60° UsS60° provides least upstream water level and downstream speed and most ratio of through to total flow for a constant discharge, and the reverse goes to the weir with downstream slope of 30° DsS30°
