Good Modelling Practise



The Institute for Inland Water Management and Wastewater Treatment (RWS/RIZA) has taken the initiative to facilitate quality assurance (QA) in modelling and simulation. In a period of 7 months the project team has produced a handbook of Good Modelling Practice. At first the project team defined the requirements to such a handbook and explored the experiences, guidelines and documents on GMP at several research institutes and in literature. Subsequent a ontology (i.e. shared body of knowledge) on modelling and simulation has been developed. A major part of the handbook consists of a survey of common problems and pitfalls, both on a general and on a model type dependent level. The present version of the handbook has been tested by inexperienced modellers (students) and experienced modellers and model users from the participating institutes.

In this handbook a wide range of water management model types is discussed:

  • groundwater quantity models
  • groundwater quality models
  • precipitation discharge models
  • water distribution models
  • hydrodynamic models
  • flood tide predictions
  • geo-morphological models
  • surface water quality models
  • calamity models
  • emission models
  • ecological models
  • economic models
  • operational models

Many organizations working in the field of water management have made commitments to participate in updating and improving the GMP-handbook and to use it in modelling and simulation studies.

  • a 2 day course on GMP for water management has been developed; please contact Huub Scholten, Simon Groot or Anne Ubbels for more info; this course has been given on May 10-11, 2001 in Ruzina Reservoir, Slowakia
  • a 1.5 day workout on GMP has been developed, using SWAP as example model (groundwater), based on the GMP course, but with emphasis on applying the GMP approach on your own model; the workout will be held Dec 12 and Dec 19, 2001. Please contact Huub.Scholten, Joop Kroes or Henk Wösten.
  • the GMP approach has been integrated in several courses at various (Dutch) universities, Wageningen University included.

GMP was one of the projects within the context of the AQUEST program 'Generic Framework Water'.


Present initiatives are:

  • updating of the Handbook
  • evaluation of the use of the Handbook (see webiste)
  • upgrading parts of the Handbook to a (national) norm for model based decision support in water management (NEN-norm of the Nederlands Normalisatie Instituut)
  • a EU-funded project HarmoniQuA of a consortium of 12 partners from 10 European countries to realize a common methodology and guidelines for model based decision support in water management and tools to support this.
