Application of stepped spillways increases the energy dissipation rate along the spillway and may reduce the dimensions of the terminal energy dissipation structure. Stepped spillways have been built since several decades in combination with roller compacted concrete dams. More recently stepped spillways are also excavated into rock along the abutments of embankment dams. For both, in some cases, an abrupt slope change may be required to be implemented on stepped chutes in order to follow the site topography and to minimize the needed excavations and hence respective costs. An abrupt slope change along stepped spillways can influence the flow properties such as the air entrainment, velocity and pressure distribution, and the energy dissipation. A quite limited number of stepped spillways have been built with an abrupt slope change, and limited systematic scientific investigation for designing such type of configuration has been conducted to date. Accordingly, comprehensive information on the effect of an abrupt slope change on the flow features is missing. To reduce this gap in knowledge, the present research work intends to examine the effect of an abrupt slope change by conducting a numerical modelling and analysing the two phase flow features along the stepped chute with slope changes.
