Hydrological models are the baseline for many questions of scientific, political and societal relevance. For instance in Europe, the EC has aligned the continent in a common policy for water in the Water Framework Directive (WFD, 2000/60/EC) and related directives on floods, groundwater, drinking water, agriculture and so forth. In addition, the Marine Strategy Framework Directive is strongly connected to activities and measures taken on land.

Integrated water assessment and management needs to look at river catchments and water bodies as a whole and requires collaboration across water divides. Today, there are tremendous problems of linking a multitude of databases, sensor networks, calculation methods and models into operational systems. New and advanced approaches must thus be developed and applied to meet many of the current legislations and future challenges.
Hydrological models are key elements for any integrated water management approach. Making them available widely, and combining them with sensors, datasets and background information into integrated decision support systems at reasonable cost is a challenge today. Moreover, new approaches for easy model coupling and sharing algorithms are desired. When looking for sustainable solutions, there is a wish to reduce uncertainties by applying an ensemble of results from several hydrological models and parameter values, which require large computational power and efficient model infrastructures. Achievements are possible through collaboration among hydrological scientists by sharing of tools, catchment information and efficient technical infrastructure.

This session aims at discussing

  • requirements of catchment-information-based environmental decision support systems; requirements which have recently evolved or which have not been satisfied up-to-date
  • needs of catchment-related applications, for instance related to the management of information in continental systems (large-scale spatial data infrastructures for water)
  • recent advances in catchment hydrology simulation
  • new technological opportunities arising from areas like high performance computing, cloud computing and others, for instance for the simulation of large ensembles of potential scenarios
  • new collaboration opportunities arising from linking both hydrology modellers and non-scientific end users through e-science infrastructures and e-science environments which support the scientific discovery process and practical use of new insights

We invite contributions addressing all aspects of catchment-related systems, but in particular those which will discuss and demonstrate deficiencies in the state-of-the-art, those which show new opportunities, even if they are at a very experimental stage, and those which can contribute to shaping the R&D needs for the upcoming decade in this field.
