Skimmer basin design
Skimmer sediment basin design, straight from Practice 6.64
Enter your drainage area and design storm; the workbench runs the full Practice 6.64 procedure — sizing the basin, the skimmer, and the emergency spillway — and shows the governing equation beside every computed value, cited to the manual page it came from.
What the workbench does
- Surface area and sediment-storage volume sizing from your design discharge and disturbed area
- Skimmer dewatering time from orifice diameter and the manual's skimmer-head table
- Practice criteria checks: depth, length-to-width ratio, dewatering window, baffle minimums
- Emergency spillway capacity using the manual's weir coefficient (Cw = 2.8) with 1 ft weir freeboard
- Design-storm runoff per Appendix 8.03 (Rational Method)
