In systematic tests on a physical model, the influence of fast and repeated change of operations between generating and pumping modes on turbulence and sedimentation process by fine sediments in a rectangular cuboid is examined. It is studied how turbulence and settling down of fine sediments is affected by discharge, duration of pumped storage sequences and the intake/outlet location.-Prior to laboratory tests, several scenarios with and without sediments were simulated in a numerical model. A comparison between the results and observations on the physical model allows optimizing both numerical and experimental setup. The present paper describes the physical modeling concept, the test rig and presents results of the preliminary numerical and hydraulic tests.
