### Formula for calculating the drainage discharge rate:
# DrainageDischargeRate = ((8*HydraulicConductivitySoilBelowDrainLevel*EquivalentDepth)
# * (DepthImpermeableLayer-DepthDrains) * (DepthDrains-DepthWatertable)
# + (4*HydraulicConductivitySoil) * (DepthDrains-DepthWatertable) )/(SpacingBetweenDrains**2)
