For observation well A15ES, the following parameter values are used in the <br />model to attain the most appropriate match: transmissivity, T, of 3750 m2 -d-1; aquifer <br />hydraulic conductivity, K, of 125 m -d-1; anisotropy ratio, K/KZ, of 7.8; specific storage, <br />Ss, of 2.5 x 10-4 m'1; specific yield, Sy, of 0.20; and a streambed hydraulic conductivity of <br />0.1 m -d "1. A comparison of the observed drawdown and the model predicted drawdown <br />with the above - mentioned parameter values is shown in Figure 6. <br />E <br />3 <br />0.1 <br />0 <br />3 <br />CU <br />L <br />r) <br />0.01 <br />• Measured Drawdown <br />Curve -Fit with STRMAQ <br />10 100 1000 10000 <br />Time, t (min) <br />Figure 6 — Comparison of measured drawdown at observation well A15ES during a <br />stream/aquifer analysis test at the Tamarack State Wildlife Area and predicted <br />drawdown by the STRMAQ model considering the influence of finite stream width <br />of the slough channel. <br />For observation well B2ES, the following parameter values are used in the model <br />to attain the most appropriate match: transmissivity, T, of 3900 m2 -d-1; aquifer hydraulic <br />conductivity, K, of 130 m -d-1; anisotropy ratio, K/KZ, of 8.1; specific storage, SS, of 2.7 x <br />104 M-1 ; specific yield, Sy, of 0.22; and a streambed hydraulic conductivity of 0.5 m -d -1. <br />A comparison of the observed drawdown at observation well B2ES and the model <br />predicted drawdown with the above - mentioned parameter values is shown in Figure 7. <br />10 <br />
