6.3 The groundwater level in a soil layer 10 m thick is located
at 3 m below the surface. (a) Plot the distribution of
hydrostatic pressure with depth. (b) If the groundwater
were to rise to the surface, plot on the same graph
as (a), using a different line type, the distribution of
hydrostatic pressure with depth. (c) Repeat (b), but the
groundwater is now 2 m above the ground surface (flood
condition). Interpret and discuss these plots with respect
to the effects of fluctuating groundwater levels.
