Description: A diagram from 1911 showing the effect of land contour on the flow direction of groundwater within a typical water table in a hilly region. The continuous lines represent landscape contour lines, the heavy black lines represent surface drainage (stream flow), and the dashed lines represent the direction of motion of groundwater within the subsurface water table.
