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. A groundwater flow computed from the coefficient a1 and exponent b1 2. A 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.
