The transmissivity of ith layer is defined product the ith layer hydraulic conductivity
[L/T] and layer thickness. Therefore, the transmissivity of the ith layer is equal to
T,= K, L, (3-26)
where Li is layer thickness, [L]. The total transmissivity of the aquifer, Ttotai, then equals:
Tota = Kave *L (3-27)
in which L is the thickness of the aquifer [L]; hence,
n
Tto0a1 = (3-28)
The injection and recovery rates for the ith layer are calculated from equations (3-
29) and (3-30):
0, = T, i (3-29)
total
QR, T, QR (3-30)
total
By defining
A,= T (3-31)
'total
and
Y, = (3-32)
L
then equations (3-29) and (3-30) reduce to:
Qi, = AQ (3-33)
QR, =A, QR (3-34)
