In a world of increasingly rapid technological and economic development, sea-level rise, and possible global climate change, central tasks facing the coastal and estuarine manager are to predict and manage change, undertaken against a background of constantly moving goalposts. There is an urgent need for a much better framework of background environmental data and more effective and reliable management tools, founded on sound scientific understanding, which can provide necessary guidance and the basis for policy formulation. Although these needs have been recognized, and some progress has been made in the past few years, of which this volume is an example, an adequate suite of such tools and frameworks for environmental monitoring is still some way off.
The broad selection of papers included in this volume reflects the wide range of research currently being undertaken in coastal and estuarine environments, but underlines the fact that there are still significant gaps in understanding and major needs for further research which crosses traditional disciplinary boundaries. This volume brings together the results of recent research of sedimentologists, geomorphologists,archaeologists, engineers and others, expounding their methods and concerns, and identifying
