The independent variables of the hydrologic <br /> <br /> <br />system such as recharge from applied water, precipitation, <br /> <br /> <br />and evapotranspiration were programmed in stages to <br /> <br /> <br />determine the effect of each on the hydrologic system. <br /> <br /> <br />For example, the first analysis of the model was made <br /> <br /> <br />by simulated well pumping and observing water-level <br /> <br /> <br />changes without recharge or evapotranspiration. Water- <br /> <br /> <br />level change maps were constructed after each variable <br /> <br /> <br />was added to the model. The changes in water level <br /> <br /> <br />predicted by the model were then compared with observed <br /> <br /> <br />changes. Refinements in first estimates of evapotrans- <br /> <br /> <br />piration and recharge will be made until the predicted <br /> <br /> <br />changes in water level match the changes measured in <br /> <br /> <br />the field. <br /> <br />. <br />
