| Abstract | The authors are to be commended for their valuable and unique comparison of experimental data for clear-water dam-break floods on steep slopes and for their nonhydrostatic shallow-water model. The dam-break experiments down a steep slope at the USGS outdoor laboratory Logan and Iverson 2007 mimic the behavior of natural flows and shed light on different mechanisms inertia, viscous dissipation, pressure gradient that control the flow dy-namics. The discusser has studied roll-wave development in dam breaks and similar problems on steep slopes restricted to rela-tively long timescales, for which the kinematic regime is reached, and the authors ’ fine results present a great opportunity to con-sider some interesting features of the dam-break wave. It is understood that there is a lack of validation of asymptotic solutions for dam-break waves on steep slopes based on the ki-nematic wave approximation Lighthill and Whitham 1955 with |
