The sliding gate of the dam is 6 meters away from the bottom of the canal. This sliding gate is operated by a counterweight system. After a short stretch of free fall, the counterweight can extend a cable operated by a pulley system to quickly open the gate. According to the video shooting mode, the estimated time to open the sliding gate is 0.2 seconds. There is a photovoltaic cell installed inside the gate, which is composed of a trigger. During each test, the data measurement and acquisition system can be activated. Regarding Test 1: Excavate a contracted river section approximately 7.80 meters long starting from the sliding gate. In the entrance and exit areas, the riverbank should be inclined at a 45 degree angle. The material for the contraction part should be "organic glass", and the extension length should be limited to 1.0 meter. Implant a probe in the middle of the contracted area to measure the height/depth of the water level during each test. In addition to this probe, two other probes are installed between the two ends of the sliding gate and the contraction part, and one is installed downstream of the sliding gate. Regarding Test 2: The end of the canal extension has an irregular width (on the right "embankment") of 2.3 meters. The depth of the flood area is 6.7 meters, and the suddenly widened part (at 90 degrees) is 6.4 meters away from the gate. In this test, 5 probes were installed in the flood prone area and 1 probe was installed in the canal downstream of the sliding gate. In two tests, the bottom of the downstream water surface was subjected to pressure by sliding gates built downstream of the canal. In order to measure water level under the specified conductivity coefficient of the flood discharge section, the probe has been improved by the engineering research institute. Test 1, which includes experiments to locally narrow the downstream of the sliding gate, not only measured data in different frequency bands, but also verified and determined one-dimensional and two-dimensional models. At present, papers containing results obtained from one-dimensional and two-dimensional models will be submitted for processing in simulation experiments with a contraction width of BC=0.015 meters. The simulation experiment guided by data from both parties resulted in a Manning Strickler coefficient of KS=100m1/3/s. In the two-dimensional model, the calculated stride Δ x and Δ y are both equal to 0.05 meters. In the one-dimensional model, if the local head loss is ignored, then the calculated stride Δ x is also 0.05 meters. In the simulation experiment, the water levels at the bottom of the upstream water surface and downstream of the sliding gate were Hm=0.003 and Hj=0.003 (relative depth within 0.01 meters), respectively.
