Water Quality Modeling: A Comparison of Transport Oriented and Biochemistry Oriented Approaches

The author was a rapporteur for the session on "Flow Related Transport Phenomena: Water Quality" at the International Conference on Numerical Modelling of River, Channel and Overland Flow for Water Resources and Environmental Applications, organized by IAHR, WMO, IIASA, and the Czechoslovakian Committee of IAHR, and held in Bratislava, Czechoslovakia, May 4-8, 1981. The request to the rapporteur was to give an overview of the related subject. This formed the first part of the original report and is published here since it considers some typical features and an apparent gap in water quality modeling, and is therefore of more general interest. The papers reviewed are listed in the Appendix
