The present paper discusses the overall hydraulic performance of the proposed Hirpura barrage on Sabarmati river near Hirpura village of Mehsana District of Gujarat. The study has been carried out using 3D physical model and HEC-RAS 5.0.7. The 3D physical model has a geometrically similar scale of 1:80 for river reach of 3 km (1 km upstream and 2 km downstream). These experimental observations, on physical models carried out at GERI, have been used to calibrate HEC-RAS based model for Manning's roughness (n). The HEC-RAS based model has been calibrated with water levels. The calibrated parameters of model are used to evaluate the performance of the barrage in the steady state condition of flow in the river reach for 10, 25, 50, 75 and 100% of design discharge 16,785 m3/s (5.9 lakh cusec). The velocities have been observed along the banks near the vicinity of the barrage using the 3D physical model, values of velocities on the left bank indicate, that protection work will be required for a reach of 500 m both on upstream side as well as downstream side on both the banks. The performance of suitable type of energy dissipation arrangement is also assessed, and horizontal apron type of energy dissipating arrangement was seen adequate which considerably justifies the performance of the barrage structure. As per the experiment on 2D sectional flume model, to protect the lifting of sand in the downstream of end sill, 10 rows of concrete block of size 1.5 m × 1.5 m × 1 m covering the length 15 m would be necessary and to protect the dislodging of these concrete blocks a launching apron of stone of 20 m length and 2 m thickness would be necessary. Thus, it can be said that with certain minor structural recommendation the hydraulic performance of the barrage can be improved.
