| Abstract | ||
| This study presents a series of experimental investigations on combined flow over curved weirs and below rectangular gate to find the hydraulic characteristics of the flow. Six combined parabolic bottom triangular weirs were constructed and tested for two different triangular angles [θw = 45° and 60°] respectively. A generalized discharge model is proposed relating the discharge coefficient(Cd) , the weir head(hw), gate opening ratio parameter in addition to weir geometry, the distance between the weir and the gate (Z), and weir opening ratio (bw/hw). Analysis of the results revealed that discharge equation is suitable for horizontal channel bed under submerged flow and for free flow. The predictions of equation shows fair agreement with experimental data. | ||
