The watershed above a city has a drainage area of approximately 952 km2. the annual average rainfall over the basin is 7.3 cm. the average annual discharge is 1 (cubic meter per second).
1) what is the annual volume of rainfall in cubic meter?
2) what is the average annual rainfall rate in cubic meter per second?
3) what is the average annual discharge in terms of mm over the drainage basin?
4) what is your estimate of the annual evapotranspiration losses from the drainage basin. how reliable do you think your estimate is?
5) estimates annual losses from the city to groundwater recharge is put at 0.265 cubic meter per second. how does this change your estimate of et in question 4?
