Optimization of flood and retention work at Cougar Creek, Canmore, Canada
Abstract
For Cougar Creek in the town of Canmore, Alberta, Canada a flood and sedimentation dosing structure is planned. Because of debris flood behavior of the creek the optimization of the opening geometry and the interaction with the planned debris filter structure is of special importance. Therefore physical scale experiments are planned. A physical scale model of the outlet structure will be rebuilt in a scale of 1:30. The input parameter like geometry, hydrology and sedimentology are delivered by the ingeneering consultancy Alpinfra. Froude scaled experiments for given stationary discharges according to the hydrological report are performed. The opening geometry and the filter structure are optimized. The roughness of the culvert will be varied in order to obtain optimized hydraulic conditions. Of special interest are sediment depositions in the culvert and the location of a possible hydraulic jump. Additionally the reach downstream the culvert is modelled under the consideration of mobile bed conditions to investigate the erosion downstream due to the bedload deposition in the basin upstream the dam. The performed experiments are evaluated and recommendations on the optimized design are given.
