Abstract

Due to high performance, stability and economics, gabion structures are widely used for protecting the hydraulic structures. GABION STEPPED WEIRS are usually used in river beds and catchments. These structures are attractive for designers because they can be used for dissipating of energy. In these weirs, there are two types of flow, inflow and over flow. The previous studies show that over flow is more effective than inflow for dissipating the energy. In this study, three sizes of plates have been used inside of GABION STEPPED WEIRS for assessing the ENERGY DISSIPATION. In the experiments, upstream slope is 1: 1, downstream slope is 1: 1, 1: 2, 1: 3, the height of the weir is 30 cm, height of the plates is 10, 20, 30 cm and the discharge differs from 10 to 40 liter per second. The width, height and length of the flume are 60 cm, 60 cm, and 11.5 m respectively. The results show that the optimum height of plate for getting maximum ENERGY DISSIPATION (82.5%) is 10 cm, which is occurred in discharge 13.5 liter per second.
