Consider three monitoring wells, each located at the vertex of an equilateral triangle.

Consider three monitoring wells, each located at the vertex of an equilateral triangle. the distance between any pair of wells is 300 m. the head at each well, referenced to some common datum, is as follows: well 1, 100 m; well 2, 100.3 m; well 3, 100.3 m. (a) sketch the well field and find the magnitude and direction of the hydraulic gradient.
