167 of the surface flow and estimate its velocity. Colored dyes and neutrally buoyant particles moving in the water column (at a fixed depth) made it possible to estimate the flow field and its velocity in characteristic areas of maximum load on the jet- directing screen and its anchor system. Visualization images of hydrodynamic processes were recorded using video and photographic equipment, followed by printing and analysis of the resulting video footage. The most informative frames and process images were digitized and entered into a personal computer for subsequent processing and analysis using specialized programs and techniques. The results of visual researches were processed on specially designed graphics stations, which allowed for accelerated or slowed-down playback of video recordings or frame-by-frame data analysis. Graphics stations based on dual- or quad-processor computers, with increased memory and performance, made it possible to observe the behavior of contrast agents and labeled particles in a complex vortex field. Pixel-level resolution allowed for a fairly accurate determination of the trajectories of labeled particles and their transport velocity vectors in the vortex flow. a b Fig. 2.
