A 500 acre watershed receives 5 inches of rain over a 36 hour period. What is the average rate of precipitation in m^3day^-1? What is the volume of precipitation that fell over this period in acre feet?
Solution
Volume of precipitation = 500acre * 5inch = 500 * 4046.86 * 5*0.0254 m^3 = 256975.61 m^3
1acre = 4046.86 m^2
1inch = 0.0254 m
Rate of precipitation = 256975.61 m^3/(1.5 day) = 171,317.07 m^3 day^-1
volume of precipitation in acre feet = 500 * (5/12) = 208.33 acre feet
