Abstract: | A review of the information available in the literature is given, and new experimental data on the depth and discharge at
the dam site after a total and a partial dam break are presented. It is shown that in the case of a partial dam break with
the formation of a rectangular breach, the specific discharge per unit width of the breach is higher than the specific discharge
in the case of a total dam break with the same excess initial energy in the headwater.
