Water Pollution VI Modelling, Measuring and Prediction

About this book

Engineers and scientists working in the field of water pollution must be familiar with a wide range of issues including the physical processes of mixing and dilution, chemical and biological processes, mathematical modelling, data acquisition and measurement. Available data is scarce and it is therefore essential that there is a continuous exchange of information between specialists from different countries. Bringing together the latest research in this area, this volume contains the proceedings of the Sixth International Conference on Water Pollution. Over fifty papers are included and these cover topics such as: Groundwater and Aquifer Contamination; Wastewater Treatment; Lakes, Rivers and Wetlands; Coastal Areas and Seas; Biological Effects; Organic Contaminants; Agricultural Pollution; Oil Spills; Mathematical and Physical Modelling; and Experimental and Laboratory Work.
