2 cards from this section. Quick, good the night before a test.
Define specific yield.
Think about what influences the drainage of water.
What does storativity refer to?
Consider how pressure affects water storage.
What is specific yield generally associated with?
Remember the context of groundwater types.
True or False: Storativity is usually greater than specific yield in confined aquifers.
Consider the impact of pressure on water storage.
Analyzing a confined aquifer, you find the storativity to be 0.005. If the pressure decreases by 20% due to pumping, how much water can be expected to be released?
You need to relate storativity with the change in pressure and define the area.
You're managing a well in an unconfined aquifer. The specific yield is 0.20. What will be the water volume released if the area of influence is 1000 square meters and the water table declines by 2 meters?
Remember how to apply the specific yield formula!
