Danish Coasts and Climate Adaptation (COADAPT) is funded by the Danish Council for Strategic Research (DFS)/Energy and Environment for the duration 1. September 2009 thru 31. August 2013
Objectives of the Project
The main objective of the project is to develop technical and shoreline management tools to meet the additional threats that an increased sea level rise and changes in storm conditions impose on coastal areas. These threats are mainly increased risk for flooding of low lying coastal areas and increased risk of coastline retreat (coastal erosion). The main objective can be divided into immediate objectives as follows:
- To develop new understanding of the impact of climate changes on the different coastal environments in terms of coastal processes and the response through coastal erosion, coastal flooding and degradation of the coastal environment.
- To develop coastal protection techniques and new sea defences, which in a sustainable way can ensure that existing and planned infrastructure and socio-economic activities can be maintained or even further developed under the new climatic conditions.
- To develop new shoreline management practices, including aspects of legislation, administration and planning, which make it possible to develop vivid and sustainable coastal societies under the new climatic conditions. This can include rehabilitation of deteriorated coastal environments.
The Project’s Expected Main Results
Coastal processes: Description of the processes and modelling tools for breaching of dunes or dikes will be developed. These will also consider the flooding process of the hinterland as a function of the breaching process as well as the timely progression of surge and waves.
Classification systems: A new coastal classification system based on morphology and exposure will be developed, which will serve as a guideline for applicable protection methodologies. A new vulnerability and risk classification system for coastal areas related to coastal flooding and coastal erosion taking into consideration land use (socio-economics), protection status and vulnerability of the coastal area and the hinterland will be developed, which will form the basis for prioritizing protection needs and measures for individual areas.
Innovative sea defence and coastal protection solutions: A new catalogue for mitigation measures for coastal areas of different risk categories in relation to flooding and coastal erosion taking into account technical possibilities as well as issues related to management, administration and planning. Ideas for future legislation and management principles will be discussed. Climate change will increase the need for coastal protection. Today the funding of coast protection projects rests entirely on the land owner; therefore the protection issue is often concentrated in a specific project in contrast to the public interest in obtaining attractive sandy shorelines based on sustainable protection projects in a larger management frame of reference.
New modelling tools: New tools for improved understanding of long term morphological development of natural or nourished coasts under the impact of sea level rise will be developed. Similarly, new tools for the study of long term morphological behaviour of coastal sections under the impact of various protection schemes will be developed.
Book on shoreline management: The Shoreline Management Guidelines (Mangor, 2004) will be extended and updated by including the effects of the changing climate on the planning process.
