Unsteady non-Darcy flow in rectangular rock-fill embankments with impervious cores was studied experimentally by subjecting the embankments to nonlinear, shallow water waves. Crushed rock and quartz were utilized, in sizes ranging from 0.7 cm - 4.4 cm, to build embankments of various widths. The embankments were tested for several wave conditions. Empirical formulas are presented for transmission, reflection, runup, and rushdown and all gave good correlations. An upward shift of the mean water level in the embankments was detected during the experiments. It was found that transmission decreased with decreasing conductivity and increasing wave steepness and embankment width, and that reflection decreased with increasing conductivity and width of embankment.
