32.3.2. Types of Basin Yield

Try these first

1. 1.

   Define 'Basin Yield' in your own words.

   Hint

   Think about the overall water resources available.

2. 2.

   What is Safe Yield?

   Hint

   Consider what it means to withdraw without causing harm.

3. 3.

   What does Safe Yield refer to?

   • The maximum extractable amount of water
   • The theoretical maximum water resource
   • The average water available yearly

   Hint

   Think about sustainable practices.

4. 4.

   True or False: Maximum Yield accounts for all possible resource extraction methods.

   • True
   • False

   Hint

   Consider what it means to maximize extraction potential.

5. 5.

   Given a river basin's Safe Yield is 1000 acre-feet per year, suggest a water management strategy that maintains this balance with increasing agricultural demand.

   Hint

   Think about how to meet demand without exceeding limits.

6. 6.

   Analyze how urbanization in a watershed with a Maximum Yield of 5000 acre-feet may impact both Safe Yield and remaining groundwater reserves.

   Hint

   Consider impermeable surfaces in your analysis.
