Updates to

The web application is now considered a demonstration of HYPE Data Delivery Service, the actual service which SMHI sells. Our offer is to deliver river forecast data to other service designers, web developers and modeling experts in standardized formats once or multiple times per day at a subscription cost. The application is used as a showcase and an example of how data from the delivery service can be visualized, but it also allows potential customers to assess the usefulness and quality of data before signing up for a subscription.

A Flash Flood Risk Map for Upper Austria is now complete – including new features and regions!

FFRM is now available for the whole state of Upper Austria (~12.000 km²). It includes:

- triangulated 25m DEM refined with the official stream network as breaklines
- 2D hydraulic calculation of maximum inundation depth originating from heavy rainfall events
- damage calculation based on water depth, land use, building density and land value.

Improvements to the SWITCH-ON Open Data Search Catalogue and Open Data Upload Tool

Recent performance and stability improvements to the SWITCH-ON Open Data Search Catalogue (BYOD) and the Open Data Upload tool have increased spatial search ability and visualization of the spatial extent of open, hydrological datasets. BYOD now contains close to 800 high quality, accurate metadata records. The Open Data Upload Tool contains many different functions that allow a user to define the requested spatial extent, upload and process shape files, provides support for NetCDF and enables zipping options.

A new model working in collaboration with SHIFT

A new hydrological model developed at TU Delft using FlexTopo will be set up for the same area as the SHIFT (SHort-term Irrigation need ForecasT) model. The models will be run in parallel simulating a forecast for water availability. Analyses will be made to determine which model performs the best and these results will be used in the SHIFT dashboard. Take a look at SHIFT here:

Results from NIGHTLIGHTS experiment published

The collaborative experiment "NIGHTLIGHTS" run in the SWITCH-ON VWLS between UNIBO and TUW partners explores the potentialities of Open Data in the context of droughts and water scarcity issues. This study analyses the spatial and temporal evolution of human presence (i.e. settlements and economic activities) close to streams and rivers in the EU Eastern Alpine region by using nighttime lights. Yearly nightlights, available at 1-km spatial resolution from 1992 to 2013, are associated to five distinct distance-from-river classes.

The APRIL Seasonal Runoff Forecast model

The new version of APRIL has added the Po River as a show case example. It also has improved the speed of loading the pages and when querying the tool. Small refinements have also been added to the graphs, tabs and the main page to increase usability. Go to our Products and Services page ( to look a Demo about the product and get full access to the product itself.

New rounds of experiments on the Virtual Water Science Lab

Seven completed experiments have been added to the VWSL, which cover diverse topics including flood generation, drought and water scarcity, water quality and changing environments. For full descriptions and further information, visit the ‘Review or Repeat’ button on the VWSL here: New experiments will be conducted this year with the VWSL. Watch this space for more details!


In July, JBA were commissioned by the Rivers Trust ( to undertake modelling, mapping and engagement for three catchments in Cumbria, UK that were affected badly in the 2015/2016 winter floods. We are investigating the effectiveness of Natural Flood Risk Management measures, and have completed the first round of ‘whole catchment modelling’ using our software JFLOW, and have engaged with the community to improve the model to understand the feasibility of implementing these measures.
