Twenty four papers from a conference on 'archaeology and the river environment' held at the British Museum in 1991. Contributors include: I K Bailiff (luminescence dating of alluvial deposits); A J Clark (magnetic dating of alluvial deposits; archaeological prospecting on alluvium); J G Evans/P Davies/R Mount/D Williams (molluscan taxocenes from Holocene overbank alluvium in southern England); B Coles (impact of beaver on temperate landscapes); J Lewin (alluvial sedimentation style in the Lower Vyrnwy, Wales); R Tipping (generation of major prehistoric valley fills in the Cheviot Hills); J Dinn/R Roseff (alluvium and archaeology in the Herefordshire valleys); C R Salisbury (evidence for palaeochannels in the Trent valley); P Clay (a Norman mill dam at Hemmington fields, Leicestershire); A G Brown/M K Keough (the geoarchaeological potential of some Midland floodplains); J J Wymer (Palaeoliths in alluvium); S needham (Holocene alluviation and interstratified settlement in the Thames valley); M Bell (archaeology under alluvium).

The first atomic bombs were constructed at the Los Alamos National Laboratory, where lab workers disposed of waste plutonium in nearby canyons leading to the Rio Grande. Today, the environmental consequences are just beginning to be understood as scientists examine the effects created by past mishandling of one of the most toxic chemical wastes known. Written in an engaging, accessible style, Plutonium and the Rio Grande is the first book to offer a complete exploration of this environmental history. It includes an explanation of what plutonium is, how much of it was released by the Los Alamos workers, and how much entered the river system directly from waste disposal and indirectly, as a result of atomic bomb fallout. The book includes extensive appendices, maps, diagrams, and photographs. Environmental managers, ecologists, hydrologists and other river specialists, as well as concerned general readers will find the book readable and informative.

"Read what over 60 internationally recognized authors say about fluvial processes, the environment, and management of gravel-bed rivers. Learn about efforts to restore more-natural ecosystem functions to adversely impacted rivers. And for some mind-stretching, consider the hydraulic/geomorphic implications of cataclysmic floods on Earth and Mars. Beginning in 1980 and held at five-year intervals, these workshops have brought together leading international researchers to present and discuss new results, concepts and state-of-the-art methods to analyze fluvial processes in and manage gravel-bed rivers. The fourth workshop was held at Gold Bar, Washington, near the dynamic Skykomish River and strikingly beautiful Cascade Mountains. Workshop papers and discussions are published to document new concepts and ideas for broad use by those who study, manage or have general interests in rivers. This fourth Gravel-Bed Rivers Workshop covers three focus topics. The first topic reviews new developments regarding fluvial processes, sediment transport and channel morphology -- in eight chapters on distinct subjects. The second and third focus topics strongly emphasize gravel-beds rivers in the environment, their influences, and their management -- in the next 19 chapters. River restoration is examined for large European and North American rivers as parts of several of the environment-management chapters. Seven appended "short papers" report on research in progress, presented at the Workshop in a poster-discussion session. Also included are two special-interest chapters -- on giving a detailed analysis and morphologic/hydraulic interpretation of cataclysmic floods and one summarizing a field exercise in management options for a long braided-meandering reach of the Skykomish River near Gold Bar."--Publisher's description.

Ten papers from a conference at the Dorset Institute in 1989. Major themes were the study of whole landscapes by geoprospection methods, and the application of new techniques. Contributions: Geoprospection in the archaeological landscape: Trace metal accumulations in soils on and around settlements (J Bintliff, B Davis, C Gaffney, A Snodgrass, A Waters); Tofts Ness, exploration and interpretation (S Dockrill, J Gater); Field magnetic susceptibility measurement from prospection and excavation (A Challands); Geoarchaeological enhancement of river valley archaeology in NE England (D Cowley, M Macklin, C O'Brien, D Passmore, T Stevenson). New Techniques and Applications in geoprospection: Phosphate survey (R Walker), Tools for the interpretation of soil phosphate data (C Buck, B Cavanagh, C Litton); Multielectrode resistivity tomography or imaging archaeology (Mark Noel); Thermal archaeological prospection (T Bellerby, M Noel, K Branigan). The Archaeologist & Geoprospection: The British Geological survey, geoprospection techniques applied to the archaeological landscape (J Allsop); Shapwick, Somerset, a study in need of remote sensing (M Aston).

This volume holds a datelist of 647 radiocarbon determinations carried out between 2004 and 2007 in support of research funded by English Heritage throught the Aggregates Levy Sustainability Fund. It contains supporting information about the samples and the sites which produced them, a comprehensive bibliography, and two indexes for reference and analysis. An introduction provides information about the scientific dating undertaken, and methods used for the analyses reported. Details of technical reports available for programmes of dendrochronology, luminescence dating, and amino-acid racemization funded under this scheme are also provided. The datelist has been collated from information provided by the submitters of samples and the dating laboratories, in order to provide easy access to raw scientific and contextual data which may be used in further research. Many of the sites and projects from which dates have been obtained are in the process of publication. Full references are given to these reports for those requiring further detail.
