A Study on the Limit of Submerged Flow in Side Channel Spilway

  • 발행 : 1972.09.01

초록

Side channel spillways based on Hinds theory were tested. Surface water level at the beginning point of side channel is the same as the crest level of weir in the usual design. Here, side channel section were moved upwards $\frac{1}{2}$ of the total head on the crest and test(revised experiment) were made. In the revised experiments, coefficients of discharge for design flood (Q) were the same with that of original design experiments. In case of 1.2Q a little influence of submergence were appeared, coefficients of discharge were decreased to be about 97.6% of that of original design experiments, therefore, Reservoir flood water level become higher about 2-3cm than original case. So revised design can be used for actual purpose and it will brings much savings in construction cost of side channel spillway.
