Abstract: Longitudinal and cross sectional water surface profiles of a side channel spillway model are presented. The model under consideration is a scale model of the prototype of an actual side channel spillway recently constructed in Iran with non-prismatic geometry and trapezoidal cross sections. Observed longitudinal water surface profiles are compared with the one- dimensional theoretical profiles. With particular attention to the differences in the results, the shape of the channel is recognized to be the governing factor. Incorporating the implications of the shape into the dynamic equation, closer agreements of theoretical and experimental water surface profiles were achieved.
