Question
The water resources director of the town from the previous problems, recommends a nearby
impounding reservoir to the City Manager for domestic water use expansion. The City Manager
has heard the reservoir has high evaporations and instructs him to explore the evaporation
volume and seek advice from SFSU engineering. The water resources director contacts you with
this information: For the month of April, the inflow to the reservoir was 1.5 cubic meters per
second. The demand from the reservoir is 1.25 cubic meters per second. The precipitation
recorded for the month was 7.62 cm and the storage volume increased by an estimated 650,000
cubic meters. The reservoir's surface area is 70.8 ha. He then asks you for the following:
a. The estimated evaporation for April:
b. The estimated evaporation depth for April:
Assumption: No water infiltrates out of the bottom of the lake.
