AbstractA free overfall at the end of the channel is used as a flow measuring device. In this paper, theoretical end depth ratio (EDR) and end depth discharge (EDD) relationships have been studied and obtained for subcritical flow in a rectangular channel with a free overfall and with different end lip shapes; i.e., triangular and skewed lip. For all models, Froude number at the brink section Fb, EDR and EDD are predicted using the theoretical relationship and compared with the values computed experimentally. The mean absolute error varies from 0.5% to 8.5% and the standard deviation varies from 0.824% to 7.35%.
