HYDRAULIC RESEARCH OF SEDIMENT TRANSPORT IN THE VERTICAL SLOT FISH PASSES

The physical model of vertical slot fishway was conducted. On the fishway a device used for sediment dispense was installed. The sediment was dispensed to each chamber. Measurements of approx. height of the water table, measurements of flow rate, observation of line streams in chambers were carried out during the studies. The flows of sediment and hydraulic parameters inside designed fishway, single compartments and their connection with sedimentation process in individual chambers were also studied. the obtained research results constitute starting point for experimental analyses and research analyses. Based on the observation and measurements it is possible to state that the constructed physical model reflects the activity conditions of the vertical slot fishway. During the studies a place of deposition in sediments of individual fishway chambers were determined.
