Little information is provided on the energy dissipation that occurs in stepped spillways with slopes less than or equal to 22° (slopes commonly found among NRCS constructed spillways). Renwick Dam in North Dakota falls in this unique class of planned rehabilitation sites for which a stepped spillway having a rather flat (4H:1V) slope is planned. To assist the NRCS in the design of this spillway, a hydraulic model study was conducted at the USDA-Agricultural Research Service (ARS) Hydraulic Engineering Research Unit (HERU) in Stillwater, Oklahoma. This paper reports the results of that study and may be used to provide design engineers with information regarding stepped spillways designed on a 4(H):1(V) slope.
