Water pollution : modelling, measuring and prediction :First International Conference on Water Pollution, Modelling, Measuring and Prediction held in Southampton, England in Sept., 1991

Water Pollution is a subject of growing concern in our industrial world. The environmental problems caused by the increase of pollutant loads dis­ charged into natural water systems have led the scientific community to pursue studies capable of relating the pollutant discharge with changes in the water quality. The results of these studies are permitting industries to employ more efficient methods of controlling and treating the waste loads, and water authorities to enforce more strict legislation regarding this matter. The present book contains edited versions of the papers presented at the First International Conference on Water Pollution (Modelling, Measuring and Prediction), held in Southampton, England, in September 1991. Its contents, which reflect the interdisciplinarity of the subject, are divided into four parts, each consisting of a keynote address and several invited and contributed papers: 1. Mathematical models (Keynote speaker: Prof. R.A. Falconer, Univer­ sity of Bradford, USA) 2. Data acquisition/monitoring/measurement (Keynote speaker: Dr. A. Plata Bedmar, IAEA, Austria) 3. Waste disposal and wastewater treatment (Keynote speaker: Prof. D.R.F. Harleman, MIT, USA) 4. Chemical and biological problems (Keynote speaker: Dr. E.I. Hamil­ ton, Environmental consultant, UK) Although the papers have been typographically edited they have been re­ produced directly from material submitted by the authors, and their content is a reflection of the authors'research and opinion.
