Ogee-crested weirs are fixed weirs and form part of the control structures. They are often used to dam a river. The weir itself consists of a massive damming body. The outer weir contours roughly correspond to a triangle. The downstream side of the weir is often designed to improve flow, in order to achieve the largest possible discharge.
The pressure distribution along the downstream side of the weir is studied with HM 163.34. The pressure measurement is realised via bores perpendicular to the surface of the downstream side of the weir. The heads are directly indicated on the integrated manometer tubes.
