Abstract: This paper gives experimental data on the propagation speed and height of a dam-break wave arising in the tailwater region during a partial dam break event. These data were used to confirm the Khristianovich calculation method.

Keywords: partial dam break, breach, discharge coefficient, dam-break wave, propagation speed.
