Investigation of Complex Flow Through Spillway-outlet Structure

Original language description

The design process and the assessment of the combined hydraulic structure on the dry retention reservoir for its hydraulic functionality are usually quite hard. Hydraulic functions of the combined hydraulic object influence each other during the various flow conditions and manipulations with the release objects. The combined hydraulic structure consisting of the fishway, two bottom outlets, and the spillway enables the variability of partial object's placing. Appropriate variation of sub-objects arrangement can be considered in terms of its hydraulic function and in parallel with some or all the sub-objects. The other suitable assessment of the arrangement variation is the effect of water flow at the end of the combined hydraulic structure, in a stilling basin, and the downstream river channel during each manipulation with the release objects. If the water downstream of the structure affects the river channel, its bed and banks, the velocity field evaluation is a suitable method for assessment. Stilling basin and the downstream channel are placed asymmetrically, so the effect on the downstream channel is one-sided. Therefore, the flume is highly stressed, and thus the maintenance costs increase. Also, the environmental function of the watercourse is disrupted. The goal of the research on the physical model was to check the hydraulic function of each combined object's part. The individual parts were placed symmetrically and asymmetrically. Different flow rates and various object settings were performed, and the riverbed and bank stress were evaluated.
