Dependence between high sea-level and high river discharge increases flood hazard in global deltas and estuaries

When river and coastal floods coincide, their impacts are often worse than when they occur in isolation; such floods are examples of ‘compound events’. To better understand the impacts of these compound events, we require an improved understanding of the dependence between coastal and river flooding on a global scale. Therefore, in this letter,...

Climate change adaptation guidelines for coastal protection and management in India

A general overview publication how to prepare the Indian coastline for climate change. The key document is Volume 1: “Climate Change Adaptation Guidelines for Coastal Protection and Management in India”. The Guidelines document (Volume I) is self-contained, with adequate information to understand the Guidelines and put them into practice. It is...

Cartagena, it's now or never: A study on reducing flood risk in Cartagena de Indias, Colombia

This report is the result of a study which aims to understand both the source and severity of flood risk in Cartagena de Indias, Bolívar, Colombia. Solutions to the problem are proposed accordingly. The flood risk is found to be severe and urgent enough to demand action. Currently annual damage and negative impact of inundations are severe...

A comparison of two global datasets of extreme sea levels and resulting flood exposure

Estimating the current risk of coastal flooding requires adequate information on extreme sea levels. For over a decade, the only global data available was the DINAS-COAST Extreme Sea Levels (DCESL) dataset, which applies a static approximation to estimate extreme sea levels. Recently, a dynamically derived dataset was developed: the Global...

New estimates of potential impacts of sea level rise and coastal floods in Poland

Polish coastal zone is thought to be one of the most exposed to sea level rise in Europe. With mean sea levels expected to increase between 28 and 98 cm by the end of the century, and storms increasing in severity, accurate estimates of the consequences of those phenomena are needed. Recent advances in quality and availability of spatial data in...

Towards a rapid assessment flood forecasting system for the Southern California coast

Coastal inundation models are benefited by timeliness of the predictions, not only when it comes to real-time forecasting but also considering risk assessment studies and sensitivity analysis. Numerical models however are often subjected to a trade-off between accuracy and efficiency, especially when dealing with large geographic scales. In this...

Upscaling coastal flood risk assessment - Insight into the uncertainty of a continental-scale model

During the last years, flood risk assessments at continental and global scales are emerging as useful tools for risk hotspot identification, support for international policy-making and harmonization of strategies for climate change adaptation. The emergence of these models comes to cover the growing demand for integrated, large-scale risk...

Flood safety in delta cities: Development of a comprehensive risk-based model to support decision making on measures against pluvial, riverine and coastal flooding in urban area, with the application to Hoboken, New Jersey

Flood safety in low-lying delta regions has been a challenge of all ages. Societies worldwide have been trying to protect themselves against flood hazards for centuries. Floods in vulnerable urban regions are often caused by heavy rainfall, high river flow, extreme sea levels, or combinations of those three. Currently, there is a lack of tools...

Coastal flooding in Southampton over the 21st century

Sea level is rising across the UK and this is expected to accelerate and to increase coastal flood risk over the 21st century. Southampton is one of the busiest and most important national ports, but coastal flooding has not been studied extensively before. This dissertation aims to investigate the likelihood of coastal flooding in Southampton...
