5 Questions
What is saltwater intrusion?
Saltwater intrusion is the movement of saltwater into fresh aquifers under the influence of groundwater development.
How does excessive pumping contribute to saltwater intrusion?
Excessive pumping leads to the lowering of the water table, contamination of wells, and the formation of a zone of contact between freshwater and seawater.
What are the geological factors affecting saltwater intrusion?
Geological factors include lithology, geomorphology, hydraulic gradient, rate of groundwater extraction, flooding seawater from paleo seawater, preservation of paleo seawater in clayey layers, and potential pathways such as fractures, deep-seated faults, and lineaments.
What is the significance of saltwater intrusion in relation to drinking water scarcity?
The main problem related to saltwater intrusion is the scarcity of drinking water as excessive withdrawal of freshwater leads to the contamination of freshwater sources.
What are the natural hazards associated with excessive withdrawal of freshwater resulting in saline water intrusion?
Excessive withdrawal of freshwater resulting in saline water intrusion can lead to various natural hazards including tsunami, storm surge, etc.
