These Proceedings are a collection of papers submitted following the 7th Symposium held in Baveno, Italy, during 22-25 September, 1996. The study of sediment/water interactions crosses disciplinary and ecosystem boundaries. The work presented in this volume demonstrates the importance of multidisciplinarity to the field with papers included in the general subject areas of sediment/water dynamics, sediment/contaminant interactions, the role of sediments in element cycles, the use of sediments as historical indicators, sediment/organism interactions, and studies of sedimentary environments in remote areas. This book will be of interest to graduate students, researchers, government regulators and environmental managers working in many areas of environmental protection and management including sedimentary geochemistry, water quality management, particle dynamics and reconstruction of environmental history
