Abstract
    Increasing demands on fresh-water resources during recent years on the one hand and the widespread availability of computer technology on the other have given a strong impulse to the development and application of modelling software for the simulation of groundwater-system behaviour. However, the knowledge of groundwater modelling and the expertise gained in its application is widely dispersed throughout many institutions in many different countries, while the complexity of the subject requires optimal use of the knowledge available. This is also true for the field of fresh- and saline-groundwater flow. In this presentation the set-up of a knowledge system for modelling fresh/saline flow is discussed, which aims at : (1) providing a structure and the information for the analysis of problem data and the selection of solution methods or models in relation to the availability of data; (2) providing information on verification of model codes and their performance during tests and applications, in as much as this information is relevant to a specific problem . In order to illustrate the suggested approach, a review is given of the validity of some commonly applied assumptions and simplifications for certain fresh-water/salt-water problem types, by means of comparing test results. Thus criteria can be derived for the application of models based on these assumptions. The implementation of this knowledge system takes place at the International Ground Water Modeling Center in the Netherlands, where much of the required information is readily available. However project will benefit from any information on model applications or model code developments from other sources.
