| Abstract: | According to St. Venant equation set, assuming the river bed is horizontal and rounding off friction item, the paper derives a general formula used to calculate the maximum dam-break flow in the case of instantaneous total dam-break, and also points out the errors of the formula used to calculate negative wave flow in wave weir intersection method to ascertain the maximum dam-break flow, prevailing throughout the country since 1962. In terms of theoretical derivation, we find that the corrected mistaken formula, in essence, a special example of derived general formulas. |
