International Water Association (IWA) Task Group on River Water Quality Modeling
Pete Shanahan is a member of the IWA Task Group on River Water Quality Modeling, which was formed to review the current practice and state of the art in river water-quality modeling and to develop alternative models based on its findings. The models developed are compatible with the existing IWA Activated Sludge Models (ASM-1, ASM-2, and ASM-3) and can be straightforwardly linked to them. The Task Group published their final report as an IWA Scientific and Technical Report:
IWA Publishing Scientific and Technical
Report No. 12
The following Task Group technical papers co-authored by Pete Shanahan are available for download:
Papers presented at Water Quality International 1998, Nineteenth Biennial Conference and Exhibition, International Association on Water Quality, Vancouver, British Columbia, Canada. June 24, 1998:

Papers presented at the 1st World Congress of the IWA, Paris 2000, Paris, France. July 4, 2000:
River Water Quality Model No. 1: I. Modelling Approach (182K) River Water Quality Model No. 1: II. Biochemical Process Equations (246K) River Water Quality Model No. 1: III. Biochemical Submodel Selection (50K)
Temperature Modeling in Surface-water Bodies
The paper, Water Temperature Modeling: A Practical Guide, was presented at the EPA Stormwater and Water Quality Model Users Group Meeting on April 12-13, 1984 in Detroit, Michigan. It provides useful advice on modeling temperature and developing the meteorological parameters needed to model temperature.
Water Temperature Modeling: A Practical Guide (555K)
The program, EQUILO, is a BASIC computer language program for computing the equilibrium temperature of a water body. An executable version for execution under MS DOS or in the DOS window in Windows is provided as is the source code developed for Microsoft QuickBASIC.
International Institute for applied systems analysis (iiasa) Research project on degraded river basins
From 1992 to 1996, Pete Shanahan contributed to the water Quality Management of Degraded River Basins in Central and Eastern Europe project at IIASA. This project focused on those rivers in the CEE countries that have been excessively polluted by municipal and industrial wastes. The project sought innovative strategies for improving water quality within the context of the social, political, and economic transition of Central and Eastern Europe.
The following papers contributed by Pete Shanahan are available for download.
