Question:
Seawater intrusion into coastal aquifers generally occurs when
Seawater intrusion into coastal aquifers generally occurs when
Show Hint
Coastal aquifers:
\[
\boxed{
\text{Over-pumping}
\rightarrow
\text{Groundwater level} \downarrow
\rightarrow
\text{Seawater intrusion}
}
\]
Updated On: Jul 18, 2026
- Recharge increases
- Pumping exceeds recharge
- Rainfall increases
- Storage increases
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Excessive pumping lowers the groundwater table and reduces freshwater pressure.
As a result, seawater moves inland into the aquifer, causing seawater intrusion.
Hence,
\[
\boxed{\text{Pumping exceeds recharge}}
\]
is the correct answer.
Therefore,
\[
\boxed{(B)}
\]
