Vital and vulnerable objects, networks

vulnerable people, animals andvital objects and networksrequire extra protection

CIrcle tool to analyse chain effects in vital infra

Tools• to identify the assignments• to support planning & design

Many, many options:

Lots of measures can be taken

Soft solutionsHard solutions

flexible and cost-effectiveless flexible, extra investment

more space but multi-functionalless space required

Blue-green solutions preferred over grey ones

Discuss and co-design solutionswith experts and stakeholders

Adaptation Support Tool

Dashboard

Ranked list of 62 blue, green andgrey adaptation measures

Dashboard

Dashboard with KPI’sbased on key figures, e.g.:

• Retention [m3]• Peak flow reduction (Treturn [yr])• Seasonal storage [m3]• Cooling effect [oC]• Groundwater recharge [mm/yr]• Water quality improvement:

• Nutrients (%)• HMs, PAHs, min. oil (%)• Bacteriological quality

• Costs (implementation and maintenance)• Benefits and ‘co-benefits’

Recent developments

First applications of these tools:

in the NetherlandsUtrecht, Dordrecht, …

abroadLondon, Beira, Oaxaca, …
