Question: the following map shows the plan view of water table...

Question details

The following map shows the plan view of water table contours in a region where there are no wells in operation. Elevations are in feet. (Note: Elevations = total heads.)

Points A, B, and C are three observation wells. A tracer injected into the aquifer at point A appears at point B after 90-day travel time with the seepage velocity (average pore velocity). Several tests indicate that the soil has a porosity of 0.28. The distance between A and B is 250 ft. The distance between B and C is 95 ft. The aquifer is homogeneous and isotropic. Calculate the water table in the observation point C. (Hint: Calculate K first)
