Table 4 <br /> Modified Tamarack Recharge Model <br /> Calibration Results for Varying Streambed Leakance <br /> Calibration <br /> Modified Tamarack Recharge Model Run Normalized <br /> RMS' <br /> Original Model - Constant Head Boundary 1.95 <br /> Modified Model <br /> Streambed Leakance = 400 day' 2.02 <br /> Streambed Leakance = 20 day' 2.03 <br /> Streambed Leakance = 1.69 day' 2.07 <br /> Streambed Leakance = 0.011 day 1 6.57 <br /> Notes: <br /> 1. The Normalized Root Mean Square (RMS) is a measure of how well the observed groundwater <br /> elevations match those calculated by the model. The smaller the normalized RMS the better the <br /> calibration. The Normalized RMS is calculated as: <br /> RMS <br /> (XObS) <br /> Where: <br /> n <br /> RMS = 1/n (Xcal — Xobs) <br /> i =1 <br /> • <br /> Xcal = Model calculated value <br /> Xobs = Observed value <br /> n = Number of observations <br /> 2. Units for streambed leakance are ft/day divided by ft which simplifies to units of 1 /day or day' <br /> 1 <br />
