With this <br />assumption made, the assumption of an isotropic aquifer, one where the <br />permeability of the soil is uniform in all three dimensions, is appropriate. The <br />aquifer beneath the central Platte River can be classified as an unconfined <br />aquifer. An unconfined aquifer is defined as an aquifer that is without an upper <br />confining layer of bedrock. The aquifer beneath the wet meadows in the Platte <br />River basin area is confined solely by a lower layer of bedrock far beneath the <br />ground surface. The flat topography of the area adjacent to the central Platte <br />river supports the assumption of an initially horizontal water table. <br />The actual mathematical solution used in this program is quite complex <br />and is discussed in detail in the article submitted by Wamer et. al. (1984). <br />Figure 2 below is adapted from that article and illustrates the artificial recharge <br />from a rectangular basin. <br /> <br />Side View <br /> <br />R <br /> <br /> <br />Ground Surface <br /> <br />Platte River <br /> <br />Mound <br /> <br />H <br /> <br />Original Wate <br />Table <br /> <br />//// <br /> <br />.
