Three piezometers located 1000 m apart bottom in the same horizontal, confined aquifer. Hydraulic conductivity is homogeneous. Piezometer A is due south of piezometer B, and piezometer C is to the east of the line AB (and 1000 m from both A and B). The surface elevations of A, B, and C are 95 m, 110 m, and 135 m respectively. The depth of water in A is 10 m, in B is 40 m, and in C is 35 m.
A. Make a map of the piezometric surface, drawing equipotential lines at increments of 5 m.
B. What is the hydraulic gradient in the aquifer?
C. If the hydraulic conductivity of the aquifer is 2 x 10^-4 m/s, what is the volumetric flux?
D. If the aquifer is 35 m thick, how much water flows across a line 1 km wide (where the line is perpendicular to the direction of groudwater flow)?
