Issue No. 1, March 2021
Welcome to the first HYPE Newsletter! We share the latest updates and developments to the model code and applications, with an overview of HYPE activities.
Last year presented challenges for us all but in moving online we were able to hold the very first HYPE online conference held in June. We then held the tenth annual HYPE course in September, online for the first time. The course and conference are planned to be held again this year, see page 3 for details.
Wishing you all a happy and safe 2021!
Latest news in the HYPE code
Multi-basin lakes are improved: Outlet lakes can be assigned to several subbasins, so called Multi-basin lakes. These now have an even water level in all lake basins, and each lake basin is assumed well-mixed. The multi-basin lake can have outlets from several of its lake basins, but the main outlet is located in the most downstream subbasin. The flow between lake basins is calculated to keep the water level equal, and so might therefore flow in both directions between two lake basins.
Current development of surface water and runoff: A new option is the model for local lake connectivity and non-contributing areas. This is used for simulating flat areas with multiple lakes with periodical outflow. River water level output can be calculated smoothly with rating curves for ice and no ice conditions. Optional models for simulating surface runoff for infiltration limited conditions are added. The calculations are based on the relation between current and maximum soil moisture and do not depend on thresholds.
The HYdrological Simulation System (HYSS): is now equipped with routines for ensemble modelling of parameter values, and specific subbasin weight on criteria for performance calculation, as well as updating of outflow with observations for concentrations.
Latest news in World-wide HYPE model development
In 2021 we will release a new version of World-wide HYPE: version 1.4. We have been continuously working to improve this model since development began in 2016. In the new version, we have focused on quality assurance for the lake information, so we can implement the last HYPE code version for improving the multi-basin lakes simulations (see “What´s new in the HYPE code”).
The global forcing data, Hydro-GFD (Berg et al., 2020) was extended until 2020 (version 3.2). The new forcing data and the new multi-basin lake code may change the water balance, so the model will be recalibrated before release. World-wide HYPE v 1.4 will be operationalized, provide forecasts, and you will be able to check it out at HYPEweb.
Water quality is now being further implemented in World-Wide HYPE. Sediments are already included but nutrients and chloride is ongoing as well as transport of waterborne plastics to the sea.
For more information about our water quality research focus, see Focus Page.

First HYPE online conference in 2020
”Learning more about the diverse applications of HYPE … internationally” and “the high scientific level” are only a couple of highlights from participants at the first HYPE Online Conference, held in June 2020.
It was amazing to see the many different ways the model has been used, and to see what past-course participants have been up to! We have a revised format for 2021, and look forward to meeting everyone again.

Open HYPE course – Online in 2020
The aim of the course each year is to teach those with hydrological modeling experience to use HYPE. You can find information about past courses at courses and training.
Coming up in 2021!
- The second HYPE online conference will be 27th – 28th May 2021.

- The annual open HYPE course is planned for autumn of 2021.
