Q$8.$Dingman chapter $9,$ problem $9.$

$[15$ points$]$

$9.$ A series of observation wells $($piezometers$)$ are installed in a straight line at varying distances from the edge of a small reservoir in Durham, New Hampshire. The table below gives the distances from the reservoir, the heights of the top of the well casing $($TOC$)$ above the ground surface, the ground$-$surface elevations, and the depth to water table from TOC as measured in October $2000$ and October $2001.$

a$.$ Calculate the water$-$table elevations at each well and the reservoir water$-$surface elevations for the two years.

b$.$ Graph the ground and water$-$table elevations along the profile for the two years. Use an appropriate degree of vertical exaggeration. Show the locations of all measurements and the calculated elevations.

c$.$ Write a paragraph summarizing your observations. Is the relation of ground water to surface water typical of humid regions?
