1.1 Short description

The HYPE model is our main tool (an open source dynamic integrated rainfall-runoff and nutrient transfer model), which provides new information, forecasts and knowledge of water resources in Sweden and world-wide, addressing different spatial and temporal scales and a broad range of users, see SMHI Hypeweb.

The input data files needed for the HYPE applications can be created in many ways. In our work at SMHI and within the Hydrology Research unit we often create these files by using the GIS-based tool from SMHI called WHIST (World Hydrological Input data Set-up Tool).

WHIST is a GIS based tool for creating and manipulating watersheds for hydrological modelling. It uses topographic databases to delineate subbasins and determine the linking between them. The software also extracts and link data from other sources (shapefiles, grids) to the subbasins.

SubbasinCreation
WHIST subbasin delineation and routing determination.

If a certain outlet is of importance to model WHIST can use so called "forced point" to force the outlet of a subbasin to hit that particular point. This procedure must be preceded by an adjustment of that point to the actual river network (ACC) since this data is used to find the delineation of the subbasins. See also the HYPE tutorial for more information.

WHIST provides a table with information about each subbasin which can be used as a base for the file GeoData.txt which is one of the mandatory files for HYPE modelling.


1.2 Forum

Please use our WHIST forum for questions and help. Perhaps you will find your answer among the former questions from WHIST users.


1.3 Download WHIST

Here you find instructions and guidelines to get started.


1.4 Disclaimer

The program started out as a collection of tools for internal use when preparing geographical data for hydrological models. So, even though the program is now being adapted to be distributed to external users, please bear in mind that there are still many functions that need more work and explanation to be useful.
