Question

. As part of the development process going on in the country, the average annual discharge at the outlet of a catchment is 0.5 m3/s. The catchment is situated in a desert area (no vegetation) and the size is 800 km2. The average annual precipitation is 200 mm/year.
a. Compute the average annual evaporation from the catchment in mm/year.
In the catchment area an irrigation project covering 10 km2 is developed. After some years the average discharge at the outlet of the catchment appears to be 0.175 m3/s.
b. Compute the evapotranspiration from the irrigated area in mm/year, assuming no change in the evaporation from the rest of the catchment.

Answer 1

the evaporation is 180.29 mm/year and evapotranspiration from irrigation project is 1205.2136 mm/year.

I hope this will help you.????
