In Baden-Württemberg, numerous hydrological models are developed and operated for research and practice. For parameterization and as model input, thematic data sets are used which are very different in terms of their collection, preparation and use. These different data bases reduce the comparability of model results, even if the respective process implementations in the models are similar. Therefore, the workshop aimed at working on the data landscape of the essential elements of hydrological models.
25 representatives from science, public authorities, associations and engineering offices attended the workshop. The programme startet with two keynote speeches: Frank Waldmann (Landesamt für Geologie, Rohstoffe und Bergbau, LGRB) presented the data bases for soils in Baden-Württemberg. Christoph Sommer (Ministry of the Environment, Climate Protection and the Energy Sector) reported on the use of data to create flood hazard maps.
Subsequently, the topics 'Soils', 'Land use', 'Topography/Terrain' and 'Hydrogeology' were discussed on four tables in two discussion sessions. The focus was on the question of which data with appropriate resolution and quality can be used for hydrological modelling. Furthermore, the strengths and weaknesses of the various data sets were discussed.
A detailed report on the results of the workshop is available as pdf in the series HydroNotes (Volume 6) of the University of Freiburg:
The workshop was organized by the KIT Coordination Office of the Water Research Network Baden-Württemberg with scientific support from Dr. Michael Stölzle, Prof. Markus Weiler and Prof. Kerstin Stahl (Chair of Hydrology and Chair of Environmental Hydrological Systems, University of Freiburg).
