Toolkit ‘Resilience Increasing Strategies for Coasts’ published in journal Coastal Engineering

Published: 8 March 2018

The RISC-KIT (Resilience-Increasing Strategies for Coasts - ToolKIT) project, lead by Deltares, developed tools to identify and prioritize the coastal zones which are most at risk. A special issue in "Coastal Engineering" is published on the results of this project. 21 papers on methods, tools, application on 10 different sites in Europe and the evaluation.

Flood risk European coastal areas

Recent and historic low-frequency, high-impact events have demonstrated the flood risks faced by exposed coastal areas in Europe. This risk is likely to increase due to climate change and on-going economic development. This projected increase in risk along coasts requires a re-evaluation of coastal disaster risk reduction (DRR) strategies and a new mix of prevention (e.g. dike protection), mitigation (e.g. limiting construction in flood-prone areas) and preparedness (e.g. Early warning systems, EWS) measures. The RISC-KIT project, funded under the FP7 program by the European Commission and coordinated by Deltares, developed the following tools to identify and prioritize the coastal zones which are most at risk.

Five developed tools

  1. The Storm Impact Database of present and historic socioeconomic and physical data;
  2. The Coastal Risk Assessment Framework (CRAF) to identify – at the regional scale (100’s km) – present and future hot spot areas of coastal risk:
  3. The Web-based Management Guide offering innovative, cost-effective, ecosystem-based DRR measures;
  4. Quantitative, high-resolution Hotspot Tool to evaluate the effectiveness of DRR measures in hot spots (with a scale of 10’s km);
  5. Multi-Criteria Analysis Tool (MCA) to assess alternative DRR measures with stakeholders.

These tools can be applied at different stages of the Disaster Management Cycle, see Figure 1, and are available as free-ware.

These tools have now been described in a number of papers in the Coastal Engineering Special Issue .

Application and validation

In addition, the tools have been applied and validated at 10 case study sites around Europe, see Figure 2. These applications have also been documented in the special issue.
