Determine the flow rate through the flow net(from Fetter – page 134)
q´ = (Kph)/f
Where: q´ = the discharge per unit width of the aquifer in the 3rd dimension
K = the permeability (cm/s)*p = the number of flow tubes bounded by adjacent pairs of flow lines
h = the head loss over the length of the flow lines (cm)f = the number of squares bounded by adjacent flow lines
The result is in cm2/s but we need to multiply that by 100 cm (unit width of the aquifer) to get flow (cm3/s) per metre along the third dimension
*For now we’ll assume that K = 0.001 cm/s for the silty-sand of the Quadra Sand here
