Climate Resilient City Tool (CRCTool)

The CRCTool explores the spatial planning of adaptation options (mainly nature-based solutions (NBS)) in an urban district. It uses a conceptual urban water balance model to calculate the hydrological effects of solutions that are drawn in by users. The CRCTool can be used on a computer to explore and compare adaptation options, or on a touchscreen for the co-creation of urban designs with stakeholders. These results are shown on a map interface and in an accompanying table. The tool provides information on the hydrological effectiveness and an indication of the construction and maintenance costs.

What you can do with it

Input

  • Select or configure an urban district.
  • Draw adaptation measures directly on the map.
  • Adjust characteristics of nature-based, hybrid and grey measures.
  • Use local rainfall, soil, land-use and heat-stress information where configured.

Output

  • Map-based adaptation scenarios and result tables.
  • Indicators for stormwater, drought, heat stress and co-benefits.
  • Indicative construction and maintenance costs.
  • Saved scenarios and reporting outputs.

Use it to

  • Explore spatial adaptation options in urban districts.
  • Compare the hydrological and heat-related effects of alternative designs.
  • Co-create urban adaptation scenarios with stakeholders.
  • Support early selection and prioritisation before detailed engineering.

Why is it relevant to climate adaptation

Helps users turn adaptation ideas into spatially explicit urban scenarios and compare more than 50 nature-based and hybrid measures. Its map-based and collaborative interface is useful for workshops and early planning, but results are indicative and depend on local input quality; detailed risk, feasibility, engineering and monetised cost-benefit assessment remain necessary before implementation.

Used in

  • Urban-district adaptation planning in international city contexts.
  • Co-creation workshops with authorities, experts and stakeholders.
  • Exploration of stormwater, drought, heat-stress and wider co-benefits.
  • Application through the Horizon 2020 REACHOUT project and Deltares services.
