Interpretive Summary:

Technical Abstract: A model study was performed to evaluate a new in-stream grade-control structure. A rock chute or loose riprap structure was modified to include three riffle-pool sequences. The structure is designed as an in-stream grade-stabilization measure that allows fish passage and biological enhancement. This paper summarizes the results of a three phase model study that examined the seepage characteristics, rock stability, flow velocities, and overall hydraulic performance of this structure. The models suggest that the structure will perform well and provide a viable new treatment technique for in-stream grade stabilization.
