What is MoST

The Water Framework Directive (WFD) provides European policy at the river basin scale and acknowledges clearly the benefits of using models. Given the integrated character of the WFD, modelling support required today comprises complex modelling studies conducted by multidisciplinary teams.

Though models are widely used in river basin management, inappropriate Quality Assurance (QA) procedures have compromised their credibility due to a series of shortcomings in modelling practice. These include ambiguous terminology, inadequate model set-up, insufficient calibration/validation, model use outside of its scope, miscommunication between modeller, water manager and stakeholders and overselling of model capabilities.

To improve the quality of modelling studies, the HarmoniQuA project developed a knowledge base (KB) with modelling guidance and a Modelling Support Tool (MoST) with the following functions:

  • Setting up multidisciplinary modelling projects;
  • Providing guidance from the kb, filtered for user roles and relevant water management domains;
  • Monitoring the work of all team members in a modelling journal;
  • Sharing modelling journal content with authorised team members;
  • Reporting to various audiences and for various purposes.

The modelling KB and MoST have been tested in 21 case studies and other projects. Training and help is available online and via courses at several universities.

The Modelling Support Tool, MoST helps managers to setting up modelling projects by specifying subprojects and domains, fine-tuning of task list, appointing and authorising team members for specific responsibilities and permissions. MoST provides modelling guidance from the KB, in a tree view (quick browsing through steps and tasks), flowchart view (order in steps and tasks) and task view (textual content of a task and its activities and methods). MoST‘s monitor component logs what team members do in a modelling journal, shared by all team members. A team member responsible for a task or an activity can enter details, attach documents and (in decision tasks) decide whether to continue with the next task or redo previous tasks. All team members (including stakeholders and public) discuss regularly on progress and how to continue.

MoST‘s reporting component filters the modelling journal into a readable and compact report for various audiences and purposes.



MoST 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)

  • KB-editor is a web based tool to facilitate developing, maintaining and upgrading ontological knowledge bases (including process knowledge bases), pre-structured in Protégé; see KB-editor;
  • ProST is the successor of MoST and can handle process knowledge bases defined with the KB-editor and provides its knowledge content as guidance for the defined process at hand; see  ProST;
  • the modelling KB is description of the modelling process (especially for model-based water management), defined in the KB-editor; see modelling KB.
