Abstract : Model investigations of the proposed channel improvements for flood control on North Gully and Sandburg Creek at South Ellenville, New York, were conducted to supplement and verify hydraulic computations for the original design and to develop alterations effecting improved hydraulic performance and reduced construction costs. A 1:20-scale model was used to verify and improve design features including the chute entrance, chute alignment, superelevation in bends, effect of large materials in the chute on flow disturbances in the chute, hydraulic performance of the stilling basin, wall heights, and elevation of bridges, and to determine the need for riprap protection below the stilling basin. The model reproduced portions of the overall project including proposed improvements along the lower 2200 ft of North Gully and approximately 600 ft of Sandburg Creek below the junction with North Gully.
