Sri Lanka's Role in Coastal Protection
### Exam-Focused Notes #### Geographical and Environmental Impact - **Location**: Sri Lanka serves as a natural barrier to the southeastern coast of India, specifically shielding it from the long-period swell waves generated in the Southern Ocean. - **Wave Impact**: Long-period swells have historically caused coastal flooding and erosion along southwestern India, particularly in Kerala, while the eastern coast (Tamil Nadu and southern Andhra Pradesh) remains largely unaffected. #### Scientific Research Findings - **Research Institutions**: Conducted by the Indian National Centre for Ocean Information Services (INCOIS) with contributions from the Department of Marine Geology at Mangalore University and the Indian Institute of Tropical Meteorology, Pune. - **Methodology**: Utilized real-time data from wave rider buoys deployed off Kollam and Pondicherry, alongside high-resolution simulations from the ‘WAVEWATCH III’ model. - **Key Data**: - Over **96%** of long-period swell events observed at Kollam did not reach Pondicherry. - Hypothetical removal of Sri Lanka from the model showed that destructive southern ocean swells could impact India’s southeast coast. #### Implications of Findings - **Climate Change Context**: The study has significant implications concerning global sea level rise and climate change, indicating that changes in coastal geography (e.g., land submergence) could alter wave propagation paths and expose new areas to marine hazards. - **Assessment and Warning Systems**: Emphasizes the importance of integrating natural geographic features into coastal hazard assessments and early warning systems, particularly in a warming world. #### Contributions and Publication - **Co-authors of Study**: T.M. Balakrishnan Nair (INCOIS director), K.G. Sandhya, R. Harikumar, P.A. Francis, and Balaji Baduru. - **Publication**: Results published in the Journal of Earth System Science, documenting the active role of the Sri Lankan Land Mass in wave dynamics. This study illustrates the interconnectedness of geographical features, meteorological phenomena, and climate change, highlighting the need for comprehensive strategies in coastal management and disaster preparedness.
