ABSTRACT
Decision Support System (DSS) are the systems that support decision-making. In practice, the support just to be provided mostly through the electronic storage, processing and visualisation of data. Groundwater Vulnerability Assessment can be described as a procedure for the quick assessment of groundwater pollution potential. It is based on intrinsic aquifer characteristics, though contaminant characteristics and management practice can also be taken into account. The Groundwater Modelling Module (GMM) has been developed to support modelling of point-source pollution problems. It consists of several software applications developed in various programming environments. The core of the GMM is an electronic Modelling Protocol guidance composed of sets of hypertext-based topics. Gathering and ordering of general knowledge on groundwater pollution problems is very labourious task, but is certainly worth doing. The developed DSS for groundwater pollution assessment appears to be one of the first attempts in the field of hydrogeology to encapsulate and actively to integrate knowledge in a comprehensive task-oriented DSS.
