Abstract: It would be greatly helpful to neophytes if knowledge-based system technology incorporating the existing heuristic knowledge about model manipulation can be integrated into the hydrological system. This paper delineates the development and implementation of a prototype knowledge-based system for model manipulation for hydrological processes by employing an expert system shell. The architecture and main components of the system are presented. The prototype system is verified and validated in two real watershed applications. It helps inexperienced users of hydrological models make the right choice of the appropriate model and/or direct the users throughout the calibration process.

Keywords: hydrological models; model manipulation; knowledge-based systems; KBS; expert systems; watershed applications; calibration; environmental pollution.
