Bioassessment of Stream-Water Quality Using Benthic and Planktonic Algae Collected Along an Urban Intensity Gradient in the Eastern Cornbelt Plains Ecoregion, Ohio, USA
Computerized modeling is becoming an integral part of decision making in water pollution control. Expert systems is an innovative methodology that can assist in building, using, and interpreting the output of these models. This paper reviews the use and evaluates the potential of expert systems technology in environmental modeling and describes elements of an expert advisor for the stream water quality model QUAL2E. Some general conclusions are presented about the tools available to develop this system, the level of available technology in knowledge-based engineering, and the value of approaching problems from a knowledge engineering perspective.
