The effective structuring of knowledge bases is most important for knowledge-based expert-system design, whilst the reliable evaluation of these knowledge bases is the key point for the acceptance of artificial intelligence technology. This paper describes the structuring and evaluation of the knowledge bases for unsteady open channel flow in a river network employing the VP-Expert shell. A tree structure and its parameter hierarchy are designed and implemented in the VP-Expert environment. The architecture of the system is described and some proofs of its satisfactory performance are given. Moreover, the manuscript discusses the experience gained through this implementation process. White-box and black-box testing strategies are used to evaluate the knowledge bases. Some typical rule errors and debugging techniques are also summarized.
