Abstract: Side weirs are hydraulic control structures widely used in irrigation, drainage networks and waste water treatment plants. These structures can be served for adjustment and diverting of flow with minimum energy loss. In spite of many studies were carried out on rectangular side weirs, the studies on oblique and labyrinth side weirs are scarce. Sadeghian [1] extensively studied the performance of triangular labyrinth side weirs with inclined bed. He conducted 161 experimental tests and introduced Eq. (1) for estimation of the De Marchi coefficient of discharge CM for triangular labyrinth side weirs with two cycles and inclined bed.
