In a groundbreaking initiative, a bathymetric study has commenced in the Pallikaranai marshland, focusing on measuring sludge volume to improve the marsh’s water retention and ecological functions.
This significant study aims to develop detailed maps of the underwater topography, essential for understanding water storage capacity and flood patterns. Bathymetry plays a crucial role in wetland restoration, land-use planning, and establishing legal boundaries.
Designated as a Ramsar site in 2022, Pallikaranai marsh faces increasing threats from encroachments and sewage discharge. Addressing these concerns, officials from the Tamil Nadu State Wetland Authority highlighted the study’s critical role in combating marsh degradation.
In collaboration with researchers, the Authority is exploring multiple locations, including Elcot, Okkiyam Maduvu, Buckingham Canal, Thangavelu Engineering College, and various parts of Pallikaranai marshland.
The study tackles two pressing challenges: wetland degradation and insufficient flood water drainage. By analyzing the marsh’s entry and exit points, researchers aim to restore natural channels and identify bottlenecks to maintain optimal water levels. The disposal of the dredged sludge will be managed carefully, ensuring proper assessment and environmental safety.
This study aligns with the National Green Tribunal’s directive to ensure clearly defined boundaries for the marshland, aimed at preventing further encroachments.
