What is the effect of conntinuous depletion of ground water along coastal region ?

Explanation

### Step-by-Step Solution:

1. **Understanding Groundwater Depletion**: Continuous depletion of groundwater refers to the excessive extraction of water from underground aquifers, which can occur due to various human activities such as agriculture, industrial use, and urbanization.

2. **Impact on Coastal Regions**: Coastal regions are particularly vulnerable to groundwater depletion because they are located near the sea. The balance between freshwater from aquifers and saltwater from the ocean is crucial for maintaining the quality of water in these areas.

3. **Saline Intrusion**: When groundwater is excessively extracted, it can lead to a phenomenon known as saline intrusion. This occurs when the natural pressure that keeps saltwater at bay is reduced, allowing seawater to move into the freshwater aquifers.
