Cd LeHe3/2 (1) Where Q represents discharge that occurs in m3/s Cd is the co coefficient of discharge Le defines the efficient waterway He is equivalent to head over crest that passes discharge Q, in meters The discharge coefficient Cd always is not constant due to factors such as; Sill’s overhead Width and shape of the sill, W Upstream slope, Zu Downstream slope, Zp Sill’s height above the floor’s upstream, P Surface roughness Figure 7: the desired values for coefficient of discharge for varying He, P and W Determination of Quantity and Width of Spans and Waterways It is essential to have in place a recommendable waterway that can allow for passage of discharge needed in...
