Discharge Equation for Proposed Self-cleaning Device

To minimize the sedimentation problems upstream of weirs and to increase the capacity and accuracy of these devices, a combination of a V-notch weir and a rectangular sluice gate was proposed and studied experimentally. Different models with different geometric combinations were tested. These geomet...
