Source: https://erdc-library.erdc.dren.mil/jspui/ ; The model study was conducted to validate the preliminary design of the constriction weir, to modify the weir dimensions as necessary to provide the desired upstream water-surface elevations, and to determine if the riprap protection blanket was adequately sized. The 1 : 10-scale model indicated the need for extending the riprap blanket downstream from the weir to ensure protection of the streambed inside the reach of the modeled area. It was also necessary to modify the constriction weir to achieve the desired upstream water-surface elevations and erosion protection. For the flow conditions tested, the riprap blanket and constriction weir design presented will provide erosion protection. _x000D_ _x000D_ NOTE: Plates 6-7 and 10-11 were removed from the final report, and thus are blank pages in the final report.
