The world’s coastal areas are increasingly at risk of flooding due to sea-level rise. We present a novel global dataset extreme sea levels, the Coastal Dataset for Evaluation Climate Impact (CoDEC), which can be used accurately map impact climate change on regions around world. third generation Global Tide and Surge Model, with resolution 2.5 km (1.25 in Europe), was simulate levels ERA5 reanalysis from 1979 2017, as well future scenarios 2040 2100. validation against observed demonstrated...
European coasts are regularly exposed to severe storms that trigger extreme water-level conditions, leading coastal flooding and erosion. Early Warning Systems (EWS) important tools for the increased preparedness response against flood events, hence greatly reducing associated risks. With this objective, a proof-of-concept Coastal Flood Awareness System (ECFAS) was developed in framework of H2020 ECFAS project, which capitalizes on Copernicus products. In context, manuscript evaluates first...
We assess the suitability of ECMWF Integrated Forecasting System (IFS) data for global modeling tropical cyclone (TC) storm surges. extract meteorological forcing from IFS at a 0.225° horizontal resolution eight historical TCs and simulate corresponding surges using tide surge model. Maximum heights Hurricanes Irma Sandy are compared with gauge observations, R2-values 0.86 0.74 respectively. other in line literature. Our case studies demonstrate that is sufficient large-scale TC By upscaling...
Abstract In the coming decades, coastal flooding will become more frequent due to sea‐level rise and potential changes in storms. To produce global storm surge projections from 1950 2050, we force Global Tide Surge Model with a ∼25‐km resolution climate model ensemble Coupled Intercomparison Project Phase 6 High Resolution (HighResMIP). This is first time that such high‐resolution used assess future surges across globe. We validate present epoch (1985–2014) against ERA5 reanalysis, which...

Abstract. Extreme sea levels (ESLs) are a major threat for low-lying coastal zones. Climate-change-induced level rise (SLR) will increase the frequency of ESLs. In this study, ocean and wind-wave regional simulations used to produce dynamic projections ESLs along western European coastlines. Through consistent modelling approach, different contributions ESLs, such as tides, storm surges, waves, regionalized mean SLR, well most their non-linear interactions, included. This study aims at...
Abstract. Tide predictions based on tide-gauge observations are not just the astronomical tides, they also contain radiational tides – periodic sea level changes due to atmospheric conditions and solar forcing. This poses a problem of double-counting for operational forecasts total water during storm surges. In some surge forecasting, regional model is run as tide-only, with astronomic forcing alone; tide-and-surge, forced additionally by surface winds pressure. The residual defined be...
<p>Climate change will lead to increases in the flood risk low-lying coastal areas. Understanding magnitude and impact of such changes is vital design adaptive strategies create awareness. In  the  context  of  CoDEC  project  (Coastal  Dataset  for  Evaluation  Climate  impact),  we  developed a consistent...
<p>In the coming decades, regions across globe will be faced with increases in coastal flooding due to sea-level rise and changes climate extremes. In a collective effort, we have produced new extreme sea level projections derived from an ensemble of high-resolution models. Our approach is based on Global Tide Surge Model forced model outputs HighResMIP experiments. The models much higher spatial resolution than previous generation models, can better resolve storms, including...
<p>European coasts are often exposed to severe storms that trigger extreme water-level conditions, leading coastal flooding and erosion. With the objective provide useful timely information on flood risk from sea level events at European scale, a proof-of-concept for Coastal Flood Awareness System (ECFAS) is being developed as part of Union’s Horizon 2020 project. ECFAS could contribute evolution Copernicus Emergency Management...
