Book Description
Alluvial fans are important sedimentary environments. They trap sediment delivered from mountain source areas, and exert an important control on the delivery of sediment to downstream environments, to axial drainages and to sedimentary basins. They preserve a sensitive record of environmental change within the mountain source areas. Alluvial fan geomorphology and sedimentology reflect not only drainage basin size and geology, but change in response to tectonic, climatic and base-level controls. One of the challenges facing alluvial fan research is to resolve how these gross controls are reflected in alluvial fan dynamics and to apply the results of studies of modern fan processes and Quaternary fans to the understanding of sedimentary sequences in the rock record. This volume includes papers based on up-to-date research, and focuses on three themes: alluvial fan processes, dynamics of Quaternary alluvial fans and fan sedimentary sequences. Linking the papers is an emphasis on the controls of fan geomorphology, sedimentology and dynamics. This provides a basis for integration between geomorphological and sedimentological approaches, and an understanding how fluvial systems respond to tectonic, climatic and base-level changes.

Regional Ground-Water Quality
Author: William M. AlleyPublisher: John Wiley & Sons
ISBN: 9780471284536
Category : Science
Languages : en
Pages : 662
Book Description
Ground water serves as the main source of drinking water for 50% of the United States as a whole—and for 97% of rural populations, in particular. In addition to public concern with point sources of contamination, such as landfills and hazardous waste disposal sites, current attention has now come to focus on the overall quality of ground-water resources. Regional Ground-Water Quality offers the first detailed guidance for conducting ground-water quality investigations in a regional context. This exceptional volume combines hydrogeologic and geochemical principles, as well as statistical principles, within a unique conceptual framework that helps readers produce efficient, meaningful, and successful ground-water assessments. Regional Ground-Water Quality will be a valuable resource when first approaching a regional-scale study and when designing specific regional-scale studies. Throughout the book, topics emphasize the value of studying regional ground-water quality at multiple spatial and temporal scales. Up-to-date coverage of essential processes and methodologies includes: multi-scale design concepts for regional ground-water quality studies the fate and transport of organic and inorganic materials, including nitrates, pesticides, pathogens, acid precipitation, natural radionuclides, saltwater intrusion, and problems in karst aquifers basic concepts of organic and inorganic chemistry a review of environmental isotopes and geochemical modeling statistical concepts for ground-water quality surveys and geostatistical analysis the effects of surface-water/ground-water interactions on ground-water quality the relationship between ground-water quality and land use regional geochemistry principles Readers will be brought completely up to date with the latest research in ground-water assessments, such as novel methods for dating young ground water, including the use of CFCs, tritium/helium-3, and krypton-85. The book also examines the uses of organic compounds as time and source markers, ground-water vulnerability analyses, applications of subsurface microbiology at the regional scale, and design of well-water surveys. Invaluable case studies drawn from international projects graphically demonstrate concepts discussed in the book. These case studies describe successful regional ground-water assessment efforts conducted in various areas and include a look at the uses and limitations of existing ground-water quality data. A first-of-its-kind resource, Regional Ground-Water Quality will be essential reading for scientists and engineers in hydrology, water resources, agricultural sciences, and environmental sciences. It will also be of interest to engineers and R&D personnel in government, industry, and private consulting, as well as to professionals involved with the design and interpretation of studies.
