168 3 0.8 10   m and 3 1.2 10   m) were used (Fig. 2a). Electrical signals from the sensors were fed to a set of Disa equipment, ensuring the operation of the hot-wire anemometers in constant-temperature mode. Averaged and pulsating velocity readings (root mean square values) were recorded in test protocols for subsequent data processing and analysis, and were also input into computers via analog-to-digital converters. In parallel, electrical signals from the output of the Disa 55M01 and 55D25 amplification unit and linearizer were recorded on a Bruel & Kaer 7005 four- channel measuring tape recorder. In addition, signals from vibration accelerometers mounted on the sensor holders, on the screen fabric, and on the walls of the measuring sections of the hydrodynamic flume and channel were recorded on a tape recorder to account for vibration interference in the measurement results. The vibration accelerometer signals were amplified and, if necessary, filtered before being transmitted to the tape recorder. The physical modeling program included the use of visual and instrumental research methods. Flow visualization using various methods allowed us to identify characteristic regions of jet and vortex flow evolution near the flexible screen and the inlet section of the jet-directing structure model. As a result, we obtained the trajectories of colored fluid regions, the directions of movement of tagged particles, and estimated their transport velocities. Velocity and pressure field measurements were taken in characteristic areas of flow interaction with the screen fabric using specially designed and manufactured sensors. Results and discussion. According to the developed research program and methodology, dyes were injected into the flow at various depths and recorded by stationary and portable video cameras. When the dye was injected before the dam (Fig. 2b), it accelerated over the dam surface. The contrast agent transfer velocity was observed lower above the portion of the dam located near the dead-end end of the flow-directing structure. Beyond the dam, the dye in the near-surface layer of the flow rushes toward the screen (Fig. 2b) and is then transported along the screen toward the open reservoir. Research results showed that a reverse flow is observed near the dam before the
