Coastal Risk Assessment

Existing coastal management and defense approaches are not well suited to meet the challenges of climate change and related uncertanities. Professionals in this field need a more dynamic, systematic and multidisciplinary approach. Written by an international group of experts, Coastal Risk Management in a Changing Climate provides innovative, multidisciplinary best practices for mitigating the effects of climate change on coastal structures. Based on the Theseus program, the book includes eight study sites across Europe, with specific attention to the most vulnerable coastal environments such as deltas, estuaries and wetlands, where many large cities and industrial areas are located. Integrated risk assessment tools for considering the effects of climate change and related uncertainties Presents latest insights on coastal engineering defenses Provides integrated guidelines for setting up optimal mitigation measures Provides directly applicable tools for the design of mitigation measures Highlights socio-economic perspectives in coastal mitigation

This book discusses how to collect data and analyze databases in order to map risk zones, and contributes to developing a conceptual framework for coastal risk assessment. Further, the book primarily focuses on a specific case study: the Bay of Bengal along the southeastern coast of India. The dramatic rise in losses and casualties due to natural disasters like wind, storm-surge-induced flooding, seismic hazards and tsunami incidence along this coast over the past few decades has prompted a major national scientific initiative investigating the probable causes and possible mitigation strategies. As such, geoscientists are called upon to analyze the coastal hazards by anticipating the changes in and impacts of extreme weather hazards on the Bay of Bengal coasts as a result of global climate change and local sea-level change.

A new ‘Multi-Coloured Manual' This book is a successor to and replacement for the highly respected manual and handbook on the benefits of flood and coastal risk management, produced by the Flood Hazard Research Centre at Middlesex University, UK, with support from Defra and the Environment Agency. It builds upon a previous book known as the "multi-coloured manual" (2005), which itself was a synthesis of the blue (1977), red (1987) and yellow manuals (1992). As such it expands and updates this work, to provide a manual of assessment techniques of flood risk management benefits, indirect benefits, and coastal erosion risk management benefits. It has three key aims. First it provides methods and data which can be used for the practical assessment of schemes and policies. Secondly it describes new research to update the data and improve techniques. Thirdly it explains the limitations and complications of Benefit-Cost Analysis, to guide decision-making on investment in river and coastal risk management schemes.

This book assists the reader in determining storm risks, focussing on sandy coasts and cliff coasts in the context of expected sea level rise from littoral transformation and climate change. It examines storm impacts through matrixes concerning physical parameters, socio-economic activities, ecological and historic resources, and it presents the Coastline Risk to Storms Index as a single numerical measure of the risk for a given area. The methodology is described and tested against two coastal areas: one in the Caribbean Sea (Cartagena, Colombia) and the other on the coast of the Atlantic Ocean (Cadiz, Spain). Both areas record an important flow of tourists associated with the “sun, sea and sand market” which represents an economic recourse for the hinterland too. Chapters describe this approach and explore three particular types of variables: i) the forcing variables contributing to storm-induced erosion, ii) dynamic variables that determine the resilience to erosion (Susceptibility) and iii) the vulnerable targets grouped in three different contexts (socio-economic, ecological and heritage). These are combined into two separate indices, the Hazard Index (combining forcing and susceptibility) and the Vulnerability Index, which together constitute the Coastline Risk to Storms Index. Maps created using this semi-quantitative approximation method can help to determine the causes, processes and consequences of storm-related processes. This book is therefore important to anyone considering coastal development programs, especially decision-makers: the work presented here can assist in the development of preventative management strategies for the most vulnerable areas.
