The coastal zone environment suffers from an increasing pressure from

economic activities, urbanization and population growth. Climate

change with effects such as sea level rise, increased flood risk and

changing temperature and rainfall patterns has even more consequences

for this area. Policy makers are forced to make both long term and

short term plans for climate change and sea level rise.

The Interreg IV B BLAST project (www.blast-project.eu) has a primary

focus on “Bringing land and sea together”, by harmonizing and

integrating data between land and sea. Work package 6 of the BLAST

project aims to develop new common policies and a web based decision

support system (DSS) supporting Integrated Coastal Zone Management

(ICZM) under the emerging climate change.

User requirements have been carried out among stakeholders in the

countries around the North Sea. These requirements have been

translated into a selection of ICZM indicators, giving a signal of

climate change. The DSS will offer the policy makers and planners

specific tools for six of these indicators being erosion, flooding due

to sea level rise, potential of renewable energy, geological

stability, urban indicators and tourism to make decisions on

mitigation and adaptation measures.

One of the indicators of the DSS is renewable wave energy potential.

The BLAST DSS will inform the user about the spatial suitability for

wave energy potential based on a GIS-based multi-criteria analysis

which takes into account factors with certain weights (e.g. distance

to harbours gains higher weights than bathymetry) and scores (e.g. the

closer to harbours, the higher the score). This suitability analysis

will be done for an area covering Belgium, the Netherlands, Germany,

Denmark and southern Norway.
