Tool ASSESSMENT and MAPPING

For local authorities, successful heavy rain risk management starts with assessment and mapping in order to identify, locate and evaluate potential heavy rain hazards and risks. Local authorities need to know where the water from heavy rain events accumulates and where it can pose hazards and risks to people, infrastructure and property on its way to the next river or lake. Mapping heavy rain hazards and risks helps to communicate the topic e.g. to citizens or emergency management services in the municipality.
This tool supports you in finding suitable methods for your municipality. Pick your starting point below.

Practitioners’ corner
This section is for municipalities who want a pragmatic approach to the topic. Here you can find basic information “which methods help me for which purpose”, “what do I need”, “whom shall I involve”, and “what needs to be done next”.

Experts’ corner
This section is for municipalities who are already familiar with the topic. Here you can find more detailed information on available approaches, experiences and scientific publications created in the context of the RAINMAN project.
Let the RAINMAN experiences guide you...
In RAINMAN, different methods and approaches to assessing and mapping heavy rain risks were tested in different landscapes (from flatlands to mountains) and area types (from urban to rural areas or agricultural land):
- all
- urban area
- rural area with hilly landscape
- rural area in flatlands
