Hybrid Physics-Guided And Data-Driven Attribution and Uncertainty Quantification of Coastal Extremes Incorporating Different Sources of Information
This project seeks to uncover the key factors driving extreme coastal flooding in Singapore. By integrating physics-based modelling with data-driven methods, it aims to deliver detailed insights into the causes and uncertainties of coastal extreme events — helping PUB, Singapore’s National Water Agency, enhance its long-term risk mitigation strategies.
Research Goals
-
Develop a hybrid physics-guided and data-driven framework to attribute and analyse coastal extreme events.
-
Predict joint probabilities of extreme sea levels and wave conditions while quantifying uncertainties through statistical confidence intervals.
-
Build stochastic climate emulators to simulate extensive ensembles of future climate scenarios.
Why This Matters
-
Provides reliable statistical estimates of extreme sea levels and wave conditions, with projections extending to 10,000-year return periods.
-
Enables scientific quantification of uncertainties, supporting more accurate forecasts of coastal hazards.
-
Offers new insights into regional climate impacts and global sea-level rise, guiding national strategies and policy decisions for coastal resilience.
Latest Research Highlights
- 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.
- 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.
- A graph-based causal inference framework is developed to investigate the causality of extreme water levels.
