AN EXPERT SYSTEM FOR THE SELECTION OF A SUITABLE METHOD FOR FLOW MEASUREMENT IN OPEN CHANNELS

The science of stream gaging has evolved through the years, mainly from the experiences and innovations of its practitioners. Stream-gaging procedures are standardized on the national and international level. However, the selection of a suitable method for flow measurement is still a fairly complex process. The knowledge-based system described in the paper is designed to aid the user in the selection process. Two aspects of selection are considered: physical characteristics of the gaging site and available equipment and/or structures at the gaging site. The system has been designed for the potential use in Environment Canada. The paper also discusses the rule-based expert system development tool, VP-Expert. Final conclusion of the research presented in the paper is that the expert system technology may help in the surface flow measurement process. The application seems to be natural, since stream gaging procedures are mainly derived from actual practice and experience. © 1990.
