Hydraulic Model Investigation: Soil Conservation Service Low Drop Structure Model Study
Abstract
The US Department of Agriculture Soil Conversation Service has been using loose riprap grade control structures based on the equal energy concept for several years with mixed success. Earlier model studies resulted in modifying the design criteria to include a 1:16-exit flare at the downstream end of the structure to return to the downstream channel width. That change resulted in a much longer structure with associated higher construction costs. This study developed a new design criteria for loose riprap drop structures that incorporates recent advances in riprap stability research, numerical backwater codes, and hydraulic model study results. The design method and tools presented herein allow the designer to optimize the size and amount of riprap used in the design.
