- Measure how environmental conditions drive changes in the seabed across Singapore’s coastline<\/li>\n
- Understand how much sediment is gained or lost along the coasts during monsoon seasons.<\/li>\n
- Trace where sediments come from and where they go, using advanced techniques and analysis.<\/li>\n<\/ul>\n\t\t
Why This Matters<\/h2>
- \n
- \nAbout 30% of Singapore’s coastline, consists of natural or partially engineered shores where nature-based and hybrid coastal protection solutions are being explored. The effectiveness of these solutions depends directly on understanding how sediments behave in these waters.\n<\/li>\n
- \nSediments are the building blocks of coastal wetlands, mangroves, and sandy shores. If the sediment supply is disrupted, these ecosystems and the coastlines they protect can erode or disappear.\n<\/li>\n
- \nSingapore currently lacks a field-based, systems-level understanding of sediment source-to-sink relationships in the Johor Strait. This project will fill that gap, providing data that coastal planners, modellers, and policymakers can use to make better-informed decisions.\n<\/li>\n
- \nWith climate projections pointing to more intense monsoons, stronger storms, and accelerating sea-level rise, establishing a reliable baseline of sediment behaviour now is critical for anticipating, and managing future coastal change.\n<\/li>\n<\/ul>\n\t\t
Latest Research Highlights<\/h2>Seasonal Seabed Mapping
\n<\/strong>\nPreliminary bathymetric surveys have already captured striking differences between monsoon and inter-monsoon periods – with significant change occurring during the Northeast Monsoon, likely driven by stronger river outflow from more northern sources.\nWater Column Characterisation<\/strong>\nEarly measurements from the eastern Johor Strait have revealed a stratified, bi-layered water column. Stronger currents drive sediment resuspension and movement along the seabed, highlighting the importance of capturing these depth-differentiated dynamics in the study.\nGeochemical Fingerprinting of Sediment Sources<\/strong>\nX-ray fluorescence (XRF) analysis of seabed sediments has revealed unexpected seasonal shifts in elemental composition suggesting that different sediment sources come into play during monsoon and inter-monsoon periods. These findings are informing the team’s approach to tracing where Singapore’s coastal sediments originate.<\/p>\n\t\t
