Coastal salinity is emerging as one of the most critical indicators of how climate change, sea-level rise, and human interventions are reshaping our coasts. Coastal aquifers, estuaries, and deltaic systems are under growing pressure from saltwater intrusion, threatening drinking water security, agriculture, and ecosystem health. Designing a robust coastal salinity monitoring network is no longer optional; it is a prerequisite for informed planning, prediction, and policy. Why salinity monitoring matters Salinity controls density-driven circulation, stratification, and mixing in coastal and estuarine waters, which in turn influence sediment transport, nutrient cycling, and habitat suitability for aquatic life. Changes in salinity patterns can signal upstream over-extraction, altered river discharge, storm surges, and sea-level rise long before they become visible crises. Continuous and spatially representative salinity measurements help in early detection of intrusion “fronts,” seasonal...
Coastal regions face increasing challenges due to climate change, sea-level rise, and saltwater intrusion—factors that directly impact freshwater availability, agriculture, and ecosystem balance. To manage these challenges effectively, accurate and continuous monitoring of coastal salinity is essential. However, one critical question remains: Where should we install salinity measurement sensors to obtain the most reliable and representative data? This forms the core of an exciting research idea — “Selection of Locations for Installation of Coastal Salinity Measurement Sensors.” The study explores multi-criteria decision analysis, GIS-based spatial modeling, and optimization techniques to identify the best sites for sensor deployment. 🎓 Why this topic matters for PG/PhD students: It combines hydroinformatics, environmental modeling, and sensor network optimization — making it both interdisciplinary and impactful. Offers opportunities to apply adva...
