Book excerpt: The great river and delta systems of the world are considered as complex, interacting systems. All components are causally interrelated. Salient process and response parameters have been identified, and procedures for acquiring and generating parameter values have been standardized. Geological, geomorphological, climatological, pedological, biological, and hydrological factors in the drainage basin, alluvial valley, deltaic plain, and receiving basin are being systematically measured, computed, and tabulated for each of 55 of the world's major rivers and deltas. Means of accurately describing the morphometry of large drainage basins by rapid electronic techniques have been devised. Values obtained are considered in relation to the water balance, soils, vegetation, and river regime. In the alluvial valley similar factors are measured. In addition, a comprehensive descriptive classification of alluvial valley landscapes has been devised. In the delta such geomorphic and environmental parameters as the relative areas of various deltaic provinces, distributary patterns, landform types, river mouth and bar types, and deltaic bulge subaerial and subaqueous geometry are determined. Process parameters, including discharge, flood peakedness, sediment load, discharge efficiency, climate, etc., are considered as in the basin and alluvial valley. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Thirty-four major river systems were compared in terms of the morphology and process environments of their drainage basins, alluvial valleys, receiving basins, and delta plains. Data for a multitude of variables, were generated and compiled for each of the 34 systems. These data were stored in a systematic hierarchical arrangement in a comprehensive information-storage-and-retrieval computer system. For purposes of comparisons between river and delta systems, optimum combinations of salinent variables were selected and were subjected to multivariate statistical procedures, including factor analysis, cluster analysis, and discriminant analysis. The procedures established the existence of some discrete groups of river systems and facilitated quantitative assessment of the degrees of mutual similarity or dissimilarity between individual river systems and between groups of two or more systems.

Download or read book Biogeochemical Dynamics at Major River-Coastal Interfaces written by Thomas S. Bianchi and published by Cambridge University Press. This book was released on 2013-10-28 with total page 673 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume provides a state-of-the-art summary of biogeochemical dynamics at major river-coastal interfaces for advanced students and researchers. River systems play an important role (via the carbon cycle) in the natural self-regulation of Earth's surface conditions by serving as a major sink for anthropogenic CO2. Approximately 90 percent of global carbon burial occurs in ocean margins, with the majority of this thought to be buried in large delta-front estuaries (LDEs). This book provides information on how humans have altered carbon cycling, sediment dynamics, CO2 budgets, wetland dynamics, and nutrients and trace element cycling at the land-margin interface. Many of the globally important LDEs are discussed across a range of latitudes, elevation and climate in the drainage basin, coastal oceanographic setting, and nature and degree of human alteration. It is this breadth of examination that provides the reader with a comprehensive understanding of the overarching controls on major river biogeochemistry.

This book was released on 2007-04-24 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rivers provide about 60 percent of the nation's drinking water and irrigation water and 10 percent of the nation's electric power needs. The multiple and sometimes incompatible services demanded of rivers often lead to policy and management conflicts that require the integration of science-based information. This report advises the U.S. Geological Survey on how it can best address river science challenges by effectively using its resources and coordinating its activities with other agencies. The report identifies the highest priority river science issues for the USGS, including environmental flows and river restoration, sediment transport and geomorphology, and groundwater surface-water interactions. It also recommends two cross-cutting science activities including surveying and mapping the nation's river systems according to key physical and landscape features, and expanding work on predictive models, especially those that simulate interactions between physical-biological processes. The report identifies key variables to be monitored and data-managed. It proposes enhancements in streamflow, biological, and sediment monitoring; these include establishing multidisciplinary, integrated reach-scale monitoring sites and developing a comprehensive national sediment monitoring program. Finally, it encourages the USGS to be at the forefront of new technology application, including airborne lidar and embedded, networked, wireless sensors.

This book was released on 2007-05-08 with total page 862 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1968 when I forsook horticulture and plant physiology to try, with the help of Sea Grant funds, wetland ecology, it didn’t take long to discover a slim volume published in 1959 by the University of Georgia and edited by R. A. Ragotzkie, L. R. Pomeroy, J. M. Teal, and D. C. Scott, entitled “Proceedings of the Salt Marsh Conference” held in 1958 at the Marine Institute, Sapelo Island, Ga. Now forty years later, the Sapelo Island conference has been the major intellectual impetus, and another Sea Grant Program the major backer, of another symposium, the “International Symposium: Concepts and Controversies in Tidal Marsh Ecology”. This one re-examines the ideas of that first conference, ideas that stimulated four decades of research and led to major legislation in the United States to conserve coastal wetlands. It is dedicated, appropriately, to two then young scientists – Eugene P. Odum and John M. Teal – whose inspiration has been the starting place for a generation of coastal wetland and estuarine research. I do not mean to suggest that wetland research started at Sapelo Island. In 1899 H. C. Cowles described successional processes in Lake Michigan freshwater marsh ponds. There is a large and valuable early literature about northern bogs, most of it from Europe and the former USSR, although Eville Gorham and R. L. Lindeman made significant contributions to the American literature before 1960. V. J.

Available in PDF, EPUB and Kindle. Book excerpt: Richard A. Davis The zone where land and sea meet is composed of a variety of complex environ ments. The coastal areas of the world contain a large percentage of its population and are therefore of extreme economic importance. Industrial, residential, and recreational developments, as well as large urban complexes, occupy much of the coastal margin of most highly developed countries. Undoubtedly future expan sion in many undeveloped maritime countries will also be concentrated on coastal areas. Accompanying our occupation of coasts in this age of technology is a dependence on coastal environments for transportation, food, water, defense, and recreation. In order to utilize the coastal zone to its capacity, and yet not plunder its resources, we must have extensive knowledge of the complex environ ments contained along the coasts. The many environments within the coastal zone include bays, estuaries, deltas, marshes, dunes, and beaches. A tremendously broad range of conditions is represented by these environments. Salinity may range from essentially fresh water in estuaries, such as along the east coast of the United States, to extreme hypersaline lagoons, such as Laguna Madre in Texas. Coastal environments may be in excess of a hundred meters deep (fjords) or may extend several meters above sea level in the form of dunes. Some coastal environments are well protected and are not subjected to high physical energy except for occasional storms, whereas beaches and tidal inlets are continuously modified by waves and currents.

Book excerpt: The size and importance of the world's rivers are measured in terms of discharge and length. A river's importance may also be measured in terms of local and regional water availability and population. A small river flowing through a densely populated, arid region may be extremely important, for example. Rivers flow downhill from their sources to their mouths at the sea. Although the world's major rivers flow through many different types of terrain, they provide similar physical and biological functions. Rivers transport sediments from their basins to the sea through the processes of erosion, transport, and deposition. In a river system's upland areas, erosion is the dominant process. Tectonic processes result in the uplift and formation of major mountain chains, while the world's major river systems help erode those mountains. A river's flow is halted when it reaches the sea, where the river deposits its sediments and creates a delta. River deltas commonly assume a triangular pattern that resembles the Greek letter delta (?) a letter based on the shape of the Nile River delta in northern Egypt. Fresh water and salt water meet in these deltas, which are some of the world's most biologically productive areas. The world's major river systems are storehouses of biological productivity and diversity. Rivers and their floodplains provide habitat for aquatic and terrestrial species. Many of the world's large rivers experience an annual flooding cycle that is important for spreading water, nutrients, and sediment into floodplains as well as providing reproductive cues for fish. This new book presents up-to-date research on this important field.

Download or read book Geology and Geomorphology of Holocene Coastal Barriers of Brazil written by Sérgio R. Dillenburg and published by Springer. This book was released on 2008-11-02 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first book to cover the Holocene geology and geomorphology of the 9,200 kilometers of the Brazilian coast. It is written for third and fourth year undergraduates, post-graduate students, scientists and man- ers. It characterizes the Brazilian coast in terms of the Holocene geology, geomorphology, oceanographic and climatic conditions, and the location, morphology and evolution of the barrier types. Separate chapters outline the types of barriers and coastal dynamics in each state, beginning in the south and proceeding to the north. Some emphasis is placed on the stretches of coast where the detailed morphology and stratigraphy of b- riers has been previously determined. To date, the Brazilian coastal barriers have been largely ignored by the international community, partly perhaps because much of the past research has tended to concentrate on barrier islands, of which there are very few in Brazil. In contrast, the Brazilian coastal barriers display a much wider range of types than is generally assumed. The biggest and most spectacular transgressive dunefield barriers in the world exist in Brazil, and dominate the southern and northeastern coasts. Many have never been described - fore. This volume provides a wealth of information on Holocene barrier types, evolution and dynamics. It provides managers, ecologists, biologists and botanists with much needed information on the geology, geomorph- ogy and dynamics of the genesis, types, functioning and ecosystems of the Holocene barriers extending along the entire Brazilian coast.
