The Groundwater Flow Component in SWMM5

Subject:  The Groundwater flow in SWMM 5 Groundwater

The Groundwater flow in SWMM 5 is actually made up of three components:

1.   groundwater flow computed from the coefficient a1 and exponent b1
2.   groundwater flow computed from the coefficient a2 and exponent b2 and
3.   A Surface Water / Groundwater Interaction coefficient a3
The total Groundwater flow is the sum of the flow from 1, 2 and 3 – normally 2 is the opposite of 1.
