### GROUNDWATER

 Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
During a thunderstorm, 1725 liters of water fall on a watershed. Of this amount, 322 liters run off into a river and 35 liters evaporate. What is the maximum amount of water that can become groundwater?
 A 1725 liters B 1368 liters C 322 liters D 35 liters
Explanation:

Detailed explanation-1: -ET=P-Q (5) where P and Q represent the total volumes of precipitation and streamflow entering and exiting the watershed during a year. Q is measured at the watershed outlet and represents the volume of water that drained by streamflow from the entire watershed over the desired duration (one year in this project).

Detailed explanation-2: -A watershed is an area of land that drains or “sheds” water into a specific waterbody. Every body of water has a watershed. Watersheds drain rainfall and snowmelt into streams and rivers. These smaller bodies of water flow into larger ones, including lakes, bays, and oceans.

Detailed explanation-3: -4.2.3 Slope of Watershed It is usually calculated as the elevation difference between the highest and lowest elevation of the point of the watershed divided by watershed length.

Detailed explanation-4: -Change in storage is calculated by subtracting the water output (runoff and evaporation) from water input (rainfall).
