Showcase
This website contains several simulations to show the various types of applications of the FastFlood model. For more detailed investigatoins, see the scientific publications around the software.
Geul, Netherlands
The Geul is a small river system in the South of the Netherlands with minor area in Belgium and Germany. In 2021, the extreme precipitation event that hit the north-western European continent resulted in floods in this area, with major damages in cities like Valkenburg.
This simulation uses automatic infiltration, channel and elevation estimates. A second model area for Valkenburg is defined using the upscaling algorithm. The observed flood extent, published by the national water and infrastructure ministry is shown as an overlay.

Grande-bay, Dominica
A flash flood simulation for the Grande-Bay area on Dominica. This area was impacted heavily in 2017 by hurricane Maria. A custom 10 meter resolution elevation model was loaded here, although similar result might be obtained using the Copernicus 30 meter elevation dataset. Land use and precipitation were loaded using the built-in tools of FastFlood. Buildings and roads are shown using the automatic download of Open Street Maps data.
See for more details the page on Dominica.
Koshi River, Nepal
A fluvial flood simulation for Koshi River in Northern Nepal. The elevation model is a 5m resolution WorldDEM Neo sattelite estimate, which is available commercially globally. A discharge boundary condition is used to simulate an extreme flow event. Surface roughness coefficients are estimated using the built-in usage of WorldCover 10m. More detailed analysis and comparison with full simulation as well as stage-discharge relationships are part of our upcoming article.
