Question

the infiltration capacity at t capacity at the end of 20 minutes and 30 minutes. (15%) 6. Your team is given an assignment to conduct a feasibility study for a new reservoir in a semi-arid region. A weather station near the project site has 35 years of rainfall data and solar radiation data. The lead engineer has a concern about the evaporation issue in the proposed reservoir and wants you to find the evaporation rate. You set up a pan at the site to observe the evaporation for one year. The evaporation record for the pan showed the loss of water as follows, what should be estimated annual evaporation depth for the proposed reservoir? (10%) Month Evaporation loss in pan Month (inches) 3.5 5.1 7.6 9.4 10.7 12.9 Jul August September October November December Evaporation loss in pan (inches) 12.8 11.7 10.5 8.2 5.4 3.8 January February March April May June

Explanation / Answer

Total evaporation =3.5+5.1+7.6+9.4+10.7+12.9+12.8+11.7+10.5+8.2+5.4+3.8=101.60

Increase of 10% can be taken means total evaporation =1.1×101.60=111.76 inches
