Raison: Information systems for managing water resources models and data

This article describes the authors’ approaches to developing information systems for water quality modelling and monitoring using an integrated systems approach. A collection of computer software programs have been developed and are designed to facilitate the development of water quality and quantity modelling and monitoring systems. These have been named RAISON Micro, for Regional Analysis by Intelligent Systems ON Micro‐computer, and incorporate geographical information systems (GIS), spreadsheet, database, graphics editor, special‐purpose data display software and expert system shell. This set of programs is suitable for IBM and IBM‐compatible microcomputers and is being adapted for SUN and IRIS workstations.
