Abstract: The end depth of a free overfall (also known as the brink depth) provides a good hint about how to measure discharge (Q). This technical note details two theoretical approaches for computing end depth ratio (EDR) and end ...

Abstract: Free overfalls offer a simple approach to determining a discharge using a single depth measurement at the end section (brink) of a channel. Fundamental equations based on the sharp-crested weir theory, both continuity and ...
