| چکیده | ||
| The effect of the entrance geometry of a culvert on the discharge coefficient is studied. The experimental results of a sharp edge model, which is compared with Bodhaine,s, are taken as the comparison base. The curved up edge model and the curved edge of a side walls model, was shown to be effective on increasing the discharge coefficient. In addition, the bottom slope, culvert length, and discharge variation have no effect on the coefficient of discharge for flow types 1, 2, and 3. | ||
