OGEE-CRESTED WEIR WITH PRESSURE
MEASUREMENT : PSAW-727FM
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. The pressure
measurement is realized via bores perpendicular to the surface of the
downstream side of the weir. The heads are directly indicated on the integrated
manometer tubes.
