Extreme sea levels, caused by storm surges and high tides, can have devastating societal impacts. To effectively protect our coasts, global information on coastal flooding is needed. Here we present the first global reanalysis of storm surges and extreme sea levels (GTSR data set) based on hydrodynamic modelling. GTSR covers the entire world's coastline and consists of time series of tides and ...

The physical causes of coastal flooding due to marine storms are discussed. We examine the costs and impacts of storm surges and waves with reference to the UK. The mechanisms of interaction between waves and the mean circulation due to tides and wind are reviewed. A case study to illustrate the magnitude of surges, waves and their interactions is presented for Liverpool Bay in the eastern Iris...

The regional waters in Singapore Strait are characterized by complex hydrodynamic phenomena as a result of the combined effect of three large water bodies viz. the South China Sea, the Andaman Sea, and the Java Sea. This leads to anomalies in water levels and generates residual currents. Numerical hydrodynamic models are generally used for predicting water levels in the ocean and seas. But thei...

Wind driven oceanic surface waves have a major impact on marine activity, especially near the coastal regions. Strong winds associated with winter storms induce storm surges along the west coast of Japan. Combined high wind conditions, tides, and storm surges can have a tremendous impact on the surface wave fields. Accurate wave forecast becomes an important issue at various operational forecas...

The storm tides, surges, and waves that are associated with typhoons/tropical cyclones/hurricanes the most severe threats to coastal zones, nearshore waters, navigational safety [...]

Designwater levels for coastal structures are usually estimated based on extreme value statistics. Since their robustness depends heavily on the sample size of observations, regular statistical updates are needed, especially after extreme events. Here, we demonstrate the exceptional influence of such an event based on storm ‘Xaver’, which caused record breakingwater levels for large parts of th...

Fluvial floods in coastal areas are affected by tides and storm surges, while the impact is seldom quantified because dynamics of seawater levels often not represented river routing models. This study established a model framework coupling surge with global hydrodynamic at higher spatiotemporal resolution than previous studies so that flood processes level fluctuation small basins can be invest...

Coastal protection design heights typically consider the superimposed effects of tides, surges, waves, and relative sea-level rise (SLR), neglecting non-linear feedbacks between these forcing factors. Here, we use hydrodynamic modelling and multivariate statistics to show that shallow coastal areas are extremely sensitive to changing non-linear interactions between individual components caused ...
