Figure 7c: Groundwater Mound at 90 degrees
4.5.2 Surface Profile of Groundwater Mound from 0 to 90 Degrees
The effects of the recharge basin as the vertical plane is rotated from 0 to
90 degrees were best displayed using a three-<Jimensional surface pial.
Figure 8 illustrates the infiuence of the recharge basin as the vertical plane of
reference is varied from 0 to 90 degrees. The front half of the groundwater
mound is shown in this graph. The different shading indicates 0.5 foot increases
in mound height. The vertical plane increases from a value of 0 degrees to a
value of 90 degrees from the back of the plot to the front of the pial.
An increase in mound height of 1 foot at a distance of 300 feet was again
apparent for vertical planes of 54 degrees or less. The increase in mound
height at 300 feet for a vertical plane of 90 degrees was nearly 1 foot as well.
