Consider the flow through a confined aquifer as shown in Fig. 6.1. The width of the aquifer is W. The depth of the aquifer is B. The total discharge in the x direction through the area WB can be written as,

Fig.6.1 A confined Aquifer

The discharge per unit width through the first Layer may be written as

(6.1) (6.2)

The discharge per unit width of the aquifer can be written as,

(6.3)

Putting T_xx = BK_xx and T_xy = BK_xy^', the equation (6.3) becomes

(6.4)

Similarly in the direction of y the discharge per unit width of the aquifer can be written as

(6.5)

Putting T_yy = BK_yy and T_yx = BK_yx^', the equation (6.5) becomes
