F <br /> ate+ <br /> CAPTURE ZONE CALCULATIONS <br /> Using the calculated aquifer parameters, capture zones can <br /> be calculated, (Keely and Tsang, 1983) . 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 /> r = _ 0 , arid: v = K dh , therefore: <br /> (21r) (b) (ee) ('V) ee dl <br /> r W 0 — - Q - r and: <br /> (21r) (b) (ee) (TC !ft-h) (21r) (Kb) (ah) <br /> (ee dl) (d1) <br /> lug T - Kb, therefore: <br /> ..1 rdg _ 0 <br /> (21r) (T) (""/dl) <br /> DEFINITIONS: <br /> r - stagnation point <br /> pumping rate <br /> 1 !Ei <br /> b = saturated thickness <br /> t # � ee = effective porosity <br /> v = true pore velocity <br /> K = hydraulic conductivity <br /> dh = hydraulic gradient <br /> d1 <br /> F T = transmissivity <br /> J <br />
