Two piezometer tips were installed in a borehole with a surface elevation of 715m. Piezometer Tip A was placed at a depth of 10m below ground surface, and Piezometer Tip B was placed at a depth of 16m below ground surface. The pressure head measured in Tip A was 3.5m, and the pressure head measured in Tip B was 13m. Calculate the hydraulic gradient and indicate its direction. Use a sketch to assist in your calculations.
