The capture zone is the <br /> area in the aquifer where groundwater that is moving under <br /> regional flow conditions will be pumped by the recovery well. . <br /> The equations used to calculate the capture zones were the <br /> following: <br /> Ir = Q _ , and: v -- K Ah , therefore: <br /> (27r) (b) (ee) (v) ee dl <br /> Ir = Q � ._ and <br /> (21r) (b) (ee) (_K_.. dh) (27r) (Kb) (dh) <br /> I (ee dl) (dl) <br /> T - Kb, therefore: <br /> rdg = Q <br /> (lir) (T) ( /dl) <br /> DEFINITIONS: <br /> r = stagnation point <br /> Q = pumping rate <br /> b = saturated thickness <br /> Iee = effective porosity <br /> v - true pore velocity <br /> K -- hydraulic conductivity <br /> 2h = hydraulic gradient <br /> dl <br /> T = transmissivity <br /> I <br /> 1 <br />
