There are three wells (A, B and C) along the hillslope, completed into the sand deposit (completed to points A, B, C). The screen for each well is shown and the point of elevation of the screen is considered at the mid-point of the screen. What is the hydraulic head, pressure head, and elevation head at wells A, B, and C (mid-points of the screens)? Which way will groundwater tend to flow, from A to B or from B to A? Please show how to calculate the vertical hydraulic gradient between A and B and indicate the direction of the gradient (up or down).
