By integrating physics-based modelling with data-driven methods, it aims to deliver detailed insights into the causes and uncertainties of coastal extreme events &#8211; helping PUB, Singapore&#8217;s National Water Agency, enhance its long-term risk mitigation strategies.<\/p>\n\t\t<h2>Research Goals<\/h2><ul>\n<li data-start=\"1409\" data-end=\"1523\">\nDevelop a hybrid physics-guided and data-driven framework to attribute and analyse coastal extreme events.\n<\/li>\n<li data-start=\"1524\" data-end=\"1675\">\nPredict joint probabilities of extreme sea levels and wave conditions while quantifying uncertainties through statistical confidence intervals.\n<\/li>\n<li data-start=\"1676\" data-end=\"1777\">\nBuild stochastic climate emulators to simulate extensive ensembles of future climate scenarios.\n<\/li>\n<\/ul>\n\t\t<h2>Why This Matters<\/h2><ul>\n<li data-start=\"2179\" data-end=\"2327\">\nProvides reliable statistical estimates of extreme sea levels and wave conditions, with projections extending to 10,000-year return periods.\n<\/li>\n<li data-start=\"2328\" data-end=\"2442\">\nEnables scientific quantification of uncertainties, supporting more accurate forecasts of coastal hazards.\n<\/li>\n<li data-start=\"2443\" data-end=\"2598\">\nOffers new insights into regional climate impacts and global sea-level rise, guiding national strategies and policy decisions for coastal resilience.\n<\/li>\n<\/ul>\n\t\t<h2>Latest Research Highlights<\/h2><strong>High-Confidence Statistical Estimates of Extreme Sea Levels and Waves<\/strong>\n<ul>\n<li>Advancing reliable predictions of ultra-extreme coastal processes (e.g. extreme wave condition) by combining Bayesian updating with statistical and physical modelling across South China Sea and around Singapore.<\/li>\n<\/ul>\n<strong>Mechanistic Insights via COAWST Simulations<\/strong>\n<ul>\n<li>An initial mechanistic analysis of how atmospheric pressure, wind-driven waves, and tidal currents jointly influence extreme water levels in coastal events is provided by fully-coupled COAWST simulations.<\/li>\n<\/ul>\n<strong>Event Directionality and Synchronization Analysis<\/strong>\n<ul>\n<li>A graph-based causal inference framework is developed to investigate the causality of extreme water levels.<\/li>\n<\/ul>\n\t\t<h2>Meet the Team<\/h2><p>Meet the
