What is the modelling KB

Modelling can be seen as a process (i.e. a series of actions). To develop a structure for the knowledge base (KB), the modelling process has been decomposed into steps (i.e. group of associated tasks), steps into tasks (i.e. activities that helps to achieve specific goals) and tasks into activities (i.e. what a team member has to do to accomplish one or more goals of a task). Task and activities can have methods (or tools) that help them to be completed.

This KB structure has been implemented in an ontology (i.e. a database with a flexible structure and approved consistency). Subsequently, the KB has been populated with expert knowledge for the following domains in water management: generic, hydrodynamics, groundwater, precipitation-runoff, flood forecasting, surface water quality, biota (ecology), socio-economics and multi-domain knowledge (i.e. on model coupling problems). A glossary of almost 1000 terms completes the KB.

The most important QA principles incorporated in the KB are:

  • The KB provides public interactive guidelines to facilitate dialogue between modeller, water manager and stakeholders.

  • External reviews are recommended at several steps during the modelling process

  • Emphasis is put on validation schemes, i.e. tests of model performance against data that have not been used for model calibration.

  • Uncertainties must be explicitly recognised and assessed (qualitatively and/or quantitatively) throughout the modelling process.



The modelling KB has been developed within the project EC funded FP5 project HarmoniQuA (Contract no: EVK1-CT-2001-00097, Duration: 2002-2005) with the following project partners:

  • Wageningen University (NL)
  • Geological Survey of Denmark and Greenland, GEUS (DK)
  • National Technical University, NTUA (GR)
  • Centre for Ecology and Hydrology (UK)
  • Delft Hydraulics (NL)
  • Centre d'etude du Machinisme Agricole du Génie Rural des Eaux et Foręts, CEMAGREF (F)
  • Bundesanstalt für Gewässerkunde (D)
  • Swedish Meteorological and Hydrological Institute, SMHI (S)
  • Vituki (H)
  • University of Dortmund – Institut für Umweltforschung, INFU (D)
  • Laboratório Nacional de Engenharia Civil, LNEC (P)
  • DHI Hydroinform a.s (CZ)
