Available in PDF, EPUB and Kindle. Book excerpt: Analyses of water- and sediment-yield records from the Walnut Gulch Experimental Watershed, the San Simon Wash Basin, and the Jornada Experimental Range, combined with observations of regional variations in climate, geology and soils, vegetation, topography, fire frequency, and land-use history, allow estimates of present conditions of water and sediment discharges in the upper Animas Creek Basin, New Mexico. Further, the records are used to anticipate fluxes of water and sediment should watershed conditions change. Results, intended principally for hydrologists, geomorphologists, and resource managers, suggest that discharges of water and sediment in the upper Animas Creek Basin approximate those of historic, undisturbed conditions, and that erosion rates may be generally lower than those of comparison watersheds. If conversion of grassland to shrubland occurs, sediment yields, due to accelerated upland gully erosion, may increase by 1 to 3 orders of magnitude. However, much of the released sediment would likely be deposited along Animas Creek, never leaving the upper Animas Creek Basin.

This book was released on 2003-11-01 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: Society for American Archaeology Book Award Winner Many fundamental studies of the origins of states have built upon landscape data, but an overall study of the Near Eastern landscape itself has never been attempted. Spanning thousands of years of history, the ancient Near East presents a bewildering range of landscapes, the understanding of which can greatly enhance our ability to infer past political and social systems. Tony Wilkinson now shows that throughout the Holocene humans altered the Near Eastern environment so thoroughly that the land has become a human artifact, albeit one that retains the power to shape human societies. In this trailblazing book—the first to describe and explain the development of the Near Eastern landscape using archaeological data—Wilkinson identifies specific landscape signatures for various regions and periods, from the early stages of complex societies in the fifth to sixth millennium B.C. to the close of the Early Islamic period around the tenth century A.D. From Bronze Age city-states to colonized steppes, these signature landscapes of irrigation systems, tells, and other features changed through time along with changes in social, economic, political, and environmental conditions. By weaving together the record of the human landscape with evidence of settlement, the environment, and social and economic conditions, Wilkinson provides a holistic view of the ancient Near East that complements archaeological excavations, cuneiform texts, and other conventional sources. Through this overview, culled from thirty years' research, Wilkinson establishes a new framework for understanding the economic and physical infrastructure of the region. By describing the basic attributes of the ancient cultural landscape and placing their development within the context of a dynamic environment, he breaks new ground in landscape archaeology and offers a new context for understanding the ancient Near East.

Download or read book Vegetation of the Glacier Lakes Ecosystem Experiments Site written by Claudia M. Regan and published by . This book was released on 1998 with total page 546 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vegetation at the Glacier Lakes Ecosystem Experiment Site, a 600 ha research site at 3200 to 3500 m elevation in the Snowy Range of southeastern Wyoming, was categorized and described from an intensive sampling of species abundances. A total of 304 vascular plant taxa were identified through collection and herbarium documentation. Plots with tree species were separated from those without tree species for ordination and classification analyses. Detrended correspondence analysis was used to order plots along major axes of composition variation, which are inferred moisture and topographic gradients. Cluster analysis was used to categorize plots based on composition similarity. The resulting groups were named according to species dominants. We identified and described in detail 4 meadow, 4 thicket or scrub, 3 krummholz, and 2 forest plant associations.

Download or read book Continental Margin Sedimentation written by Charles A. Nittrouer and published by John Wiley & Sons. This book was released on 2009-03-12 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume on continental margin sedimentation brings together an expert editorial and contributor team to create a state-of-the-art resource. Taking a global perspective, the book spans a range of timescales and content, ranging from how oceans transport particles, to how thick rock sequences are formed on continental margins. Summarizes and integrates our understanding of sedimentary processes and strata associated with fluvial dispersal systems on continental shelves and slopes Explores timescales ranging from particle transport at one extreme, to deep burial at the other Insights are presented for margins in general, and with focus on a tectonically active margin (northern California) and a passive margin (New Jersey), enabling detailed examination of the intricate relationships between a wide suite of sedimentary processes and their preserved stratigraphy Includes observational studies which document the processes and strata found on particular margins, in addition to numerical models and laboratory experimentation, which provide a quantitative basis for extrapolation in time and space of insights about continental-margin sedimentation Provides a research resource for scientists studying modern and ancient margins, and an educational text for advanced students in sedimentology and stratigraphy
