SOME ASPECTS OF SEDIMENTATION POND DESIGN

Erosion and sedimentation are normal geologic processes which are usually accelerated by irrigating agricultural lands. Of the sediment in irrigation runoff, 70% was removed in a sedimentation pond. Removal efficiency correlated well with flow rate and sediment concentration. Pond design should provide maximum velocity reduction early in ponding, allow adequate storage space for the larger particles, and decrease the flow depth toward the outlet while maintaining a constant forward velocity. This requires a fan-shaped pond, deeper at the inlet and decreasing in depth while increasing in width toward the outlet. This pond shape fits well into natural swales or draws.
