Infiltration Trench
Infiltration Trench
(OP)
Does anyone have a good way to model a sloped infiltration trench? I have a 5 ft wide trench, 3 feet deep with, 300ft long at about 1.5% slope. Do you just set up the model with multiple custom stage storage? Do you need to have some sort of outlet from each storage to the next?





RE: Infiltration Trench
However, your slope of 1.5% over 300 feet means that the trench drops 4.5 feet over it's length. Since the drop is greater than the nominal 3 foot depth, you really only have 3 feet of available depth (at the low end) tapering to zero depth after 200 feet. The remaining 100 feet will never hold any water - assuming a level water surface.
