What is basin yield?
Think about the timeframe and volume of water.
What is safe yield?
Focus on sustainability.
What is the concept of basin yield?
Think about extraction not area or rainfall.
True or False: Safe yield is the maximum quantity of water a basin can provide sustainably.
Consider what 'sustainable' means in this context.
A basin has a safe yield of 1000 m³/day and a maximum yield of 3000 m³/day. If the average daily withdrawal is 800 m³, what is the sustainable withdrawal rate?
Focus on the definition of safe yield.
Assuming a basin has a total storage capacity of 5000 m³ and a mass curve indicates inflow provides 3000 m³, how much additional storage is needed to meet a demand of 4500 m³?
Assess the difference between storage needs and available inflow.
