"WebThis would suggest using a weir coefficient that is typical of a broad-crested weir with a long crest length (i.e. C = 2.6). However, for dams with a relatively low volume of water in comparison to the height of the dam, the peak flow may occur during the phase of the breach in which the breach is still cutting down through the dam.
