For a given watershed, you have an annual precipitation estimate of 22 inches and an average discharge rate of 735 cubic feet per second. If the watershed is 1,000 mi2, what is the annual rate of discharge and ET in inches per year (assume that the system is in a steady state)?
A soil has an initial volumetric water content of 0.25 and volumetric water content at saturation of 0.45. How deep will 10 mm of rainfall saturate the soil? What is the porosity of the soil?
