Sediment volume (Vsed).
(1)
Each basin must store the volume of sediment
expected to accumulate between basin
cleanouts. The value used to predict sediment
volume (Vsed) must be based on the expected
vehicle soiling and number of basin cleanings
per year. Heavy soiling can be expected on
vehicles returning from training exercises in
off-road areas that have wet field conditions
