What's New – DynamicFlood: Cleaning up rain events and adding historical rains, now available in France

Jul 1, 2025

Today we are releasing a number of updates to Core+ DynamicFlood:

  • DynamicFlood is now available in France!
  • The national rains in Denmark changed to vary by region.
  • We have restructured the display of national rains, making it easier to select the events you care about.
  • You can now easily adjust climate factors and other rain parameters.
  • We have added historic rain events to some countries, and we're working on adding them in more countries.
  • For the technically inclined: We have switched to a new way of discretizing CDS rains; see the changelog for more information.

Below we dive deeper into some of these:

DynamicFlood in France

Combining our French land cover map with our Topsoil map (using data from soilgrids.org) and lots of rain data, we have set up Core+ DynamicFlood for France. We are excited to bring the power and simplicity to yet another Scalgo Live Country.

Regional national rains in Denmark

Using data from Spildevandskomiteen, we have released regional rain events in Denmark. This means that when you create future DynamicFlood computations, the rain event will be specific to the location of the workspace. For more information, please consult the documentation.

Historic rains

It is often relevant to run on on interesting historic events, instead of design storms. To facilitate this, we have begun adding famous historical events to the countries where DynamicFlood is available, starting with Denmark, Sweden and France. The rains can be inspected from the "run hydrodynamic engine" dialog in those countries.

Reorganization of rain dialog

We have reorganized the rains in DynamicFlood, making them easier for you to find, and to make room for the historic rains. We have done this by grouping relevant rain events together so you can quickly get an overview of the available scenarios and select the return periods you are interested in.

The rain setup in Germany where the rains are grouped into "Future climate" and "Present climate" categories.

New options to configure the rain events

At the same time we are introducing some powerful new way to configure rain events and adjust various settings. For instance, it is now easy to change the climate factor for an individual return period, or a whole set of return periods at the same time. 

Editing a set of rain events now allows you to change the climate factor. In countries where the rain is based on Chicago Design Storms, you can set CDS parameters, including the symmetry coefficient and the duration.

Remember: you can always get more information about the rains used in your country through the rain documentation and the relevant country-specific manual page.
