V-Notch Weirs & Tanks

V-Notch Weirs & Tanks

Used to measure seepage water flows on open streams, channels and tanks.
Geosense V-Notch weirs and tanks are used mainly as part of Dam Safety Monitoring programs.
Made from high quality stainless steel or other corrosion & abrasion resistant materials they are available in a wide range of sizes and angles to suit project requirements.
The V-notch weir uses the principle of flow of water over a triangular or rectangular notched weir plate. For a given profile size and shape, discharge is a function of the head of water at the weir.
Standard experimentally determined formulae (e.g. Kindsvater-Carter) are available which calculate the head of water to the rate of discharge.
