hree wells are drilled in an unconfined aquifer with the following coordinates and observed heads: Well 1: 0,200 (meters) 50 (meters) Well 2: 240,130 54 Well 3: 140, 320 63
(a) Find the magnitude and direction of the hydraulic gradient. Hint: flow is in the SW direction.
(b) Compare your results to those provided by the "EPA hydraulic gradient calculator."
