FAQs on Storativity and Specific Storage (Confined Aquifers) Video Lecture - Civil Engineering Optional Notes for UPSC

1. What is storativity in confined aquifers?
Ans. Storativity in confined aquifers is a measure of the aquifer's ability to store and release water under pressure. It is the ratio of the volume of water that a saturated unit of aquifer material will yield to the decrease in hydraulic head.
2. How is specific storage different from storativity in confined aquifers?
Ans. Specific storage in confined aquifers is the volume of water that a unit volume of aquifer material releases or takes in when the hydraulic head changes by one unit. It is different from storativity, which measures the aquifer's ability to store water under pressure.
3. How are storativity and specific storage calculated for confined aquifers?
Ans. Storativity is typically calculated using pumping tests or by analyzing the response of the aquifer to changes in hydraulic head. Specific storage is calculated based on the compressibility of the aquifer material and the change in hydraulic head.
4. Why are storativity and specific storage important in confined aquifers?
Ans. Storativity and specific storage are important in confined aquifers because they help in understanding the aquifer's ability to store and release water under pressure. This information is crucial for managing water resources and predicting groundwater flow.
5. How do storativity and specific storage impact groundwater flow in confined aquifers?
Ans. Storativity and specific storage influence the rate at which water can be stored and released in confined aquifers, affecting groundwater flow. Understanding these parameters is essential for accurate modeling of groundwater systems and predicting the response to pumping or recharge.
