Hydraulic Prototype Observation Tests on Reconstructed Energy Dissipation Facilities

In order to assess the effectiveness of reconstructed energy dissipation facilities (EDFs) in open channels at hydropower stations, hydraulic prototype observation (HPO) tests are conducted investigate characteristics discharge flow and dynamic response structures during sluice opening periods. While model (HMTs) commonly utilized laboratory settings study these characteristics, experimental conditions cannot fully replicate real-world operations such structures. HPO employed examine patterns, free water surface fluctuations, pulsating pressure changes under varying flood (FDCs). Flow patterns recorded via video; fluctuations measured using total-station laser rangefinder instruments; is monitored with sensors data collection systems. pattern observations concentrate on addressing adverse phenomena, as turbulence, surging, backflow. The examination aims verify whether height guide wall along channel fulfills necessary requirements EDF. To comprehend variations within continuous sill base slab, nine measurement points were established across three sections perpendicular sill’s axis distinct elevation levels. Additionally, positioned reinforced slab channel’s axis. findings indicate that impact caused by discharging more severe when rate a single gate reaches 500 m3/s than other FDCs. ensure safe operation discharge, for each should be reduced 250 m3/s. dominant pulsation induced falls low-frequency range, resulting minimal effects stilling basin wall. remains stable various FDCs, no significant phenomena observed. Parameters, including variations, lie acceptable ranges. These suggest arrangement generally effective following technical reconstruction.
