Problem 1
In a small town with an area of 36 km² that relies solely on groundwater for its water supply, several
factors contribute to the water balance of the aquifer:
●
River Recharge: The river flowing through the town, with a flow rate of 16,000 m³/s, contributes
0.0001% of its water to recharge the aquifer.
● Upgradient Groundwater: Upgradient groundwater flows into the aquifer at a rate of 10 gallons
per minute (GPM).
Aquifer Discharge: The aquifer naturally discharges at a rate of 4 GPM.
Average Daily Demand: The average daily demand is 250 liters per capita per day.
●
Infiltration from Precipitation: With an average annual precipitation of 300 mm, 30% of which
infiltrates into the unconfined aquifer.
●
Given these parameters and neglecting other factors, such as evapotranspiration, determine the
maximum service population that can be sustained without causing a decrease in the water table.
