Drops or free overfall are the most common hydraulic structure used in irrigation channels, water distribution and wastewater collection networks, and in recent years in stepped spillways. To reduce earth fill expenses in locations where channel slopes are less than the ground slopes, drops are provided. A vertical drop is a structure where the flow passes over a vertical fall and descends into the, downstream of the drop (Fig.
