Design of sediment retention basins

TLDR: In this article, the basic concepts and methods for the hydraulic design of sediment retention basins are described, and a rational design procedure is also outlined; however, the information presented is general in nature; thus the limitations and underlying assumptions should be recognized when applied to specific site situations.

Abstract: In the foregoing presentation, the basic concepts and methods for the hydraulic design of sediment retention basins are described. A rational design procedure is also outlined. The information presented is general in nature; thus the limitations and underlying assumptions should be recognized when it is applied to specific site situations. Modification or refinement of the suggested procedures may also be required to accommodate specific design objectives or site conditions. Furthermore, the use of basin trapping should not be viewed as the only means of sediment control. Judicious application of other on-site control measures for preventing excessive soil erosion from the site, in conjunction with a sediment retention basin, normally provide a more cost effective solution to the overall sediment problem. It is hoped that, through application of the methodology presented, the design of a sediment retention facility can be approached in a more effective manner.
