Download or read book Artificial Structures and Shorelines written by H. Jesse Walker and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 700 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is the result of an initiative of the Commission on the Coastal Environment of the International Geographical Union. The initial concept from which the plan has proceeded was presented at the 24th International Geographical Congress in Japan in 1980. AUTHORSHIP AND COVERAGE All of the articles in this volume have been written by specialists familiar with the coastal segment discussed. Nearly all have been prepared by citizens of the country (and, for that matter, even each subregion) considered. In the case of exceptions (e.g. Suriname), the authors have conducted fieldwork on the coast of the country they treat. In order to preserve the "on-the-spot" integrity of the volume, it was decided not to fill in the blanks along the world's coastline with library researched chapters. Thus, coverage is variable. Nearly every coastal country in Europe is represented whereas for Africa and South America there are major gaps. In addition, there are 2 instances of overlap. In the case of England (with a shoreline of nearly 3,000 km) a complementary chapter on Lincolnshire (with a shoreline of only 155 km) is included. The other case is the general article on the Baltic Coast of the USSR which is supported by chapters on Estonia and Lithuania.

Download or read book Geomorphology and Flood plain Vegetation of the Sprague and Lower Sycan Rivers Klamath Basin Oregon written by Jim E. O'Connor and published by . This book was released on 2015 with total page 121 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study provides information on channel and flood-plain processes and historical trends to guide effective restoration and monitoring strategies for the Sprague River Basin, a primary tributary (via the lower Williamson River) of Upper Klamath Lake, Oregon. The study area covered the lower, alluvial segments of the Sprague River system, including the lower parts of the Sycan River, North Fork Sprague River, South Fork Sprague River, and the entire main-stem Sprague River between the confluence of the North Fork Sprague and the South Fork Sprague Rivers and its confluence with the Williamson River at Chiloquin, Oregon. The study included mapping and stratigraphic analysis of flood-plain deposits and flanking features; evaluation of historical records, maps and photographs; mapping and analysis of flood-plain and channel characteristics (including morphologic and vegetation conditions); and a 2006 survey of depositional features left by high flows during the winter and spring of 2005-06. Analyses focused on the channel and flood plain within an area defined as the "geomorphic flood plain," an area encompassing active fluvial and riparian processes. The geomorphic flood plain was subdivided into 13 valley segments of distinct fluvial environments on the basis of valley form and major tributary junctions: nine segments span the 136.1 kilometers of main-stem Sprague River, two segments for the lower Sycan River, and one segment for each part of the South Fork Sprague and North Fork Sprague Rivers within the study area. Segment characteristics range from steep and narrow canyons to low-gradient reaches with expansive flood plains. The wide flood-plain valley segments are broadly similar; most contain a sinuous, low-gradient channel that migrates slowly across the valley bottom. The narrow valley segments include the steep, boulder-and-cobble-bed reaches at downstream and upstream ends of the study area as well as other confined valley segments that have similar gradients and substrates as adjacent unconfined valley segments, but much lower sinuosities. Although the geologic setting of the expansive South Fork valley segment resulted in historical conditions of sinuous and poorly defined channels and wet meadows, flanking levees now narrowly confine the channelized South Fork Sprague River for much of its length. Stratigraphic analyses show that before the Mazama eruption of 7,700 calendar years before present, wetlands and low flood plains flanked the main rivers of the study area. The eruption, however, covered much of the northern basin with sand- and granule-size pumice clasts, transforming channels by increasing bed-material transport and promoting bar formation and channel migration, particularly for the Sycan and North Fork Sprague Rivers, and for the Sprague River downstream of the Sycan River confluence. The South Fork Sprague River, which had much less Mazama pumice deposited in its watershed, remained a wet-meadow fluvial system until historical channelization and diking. The analysis of historical maps and aerial photographs covering the geomorphic flood plain show changes in sinuosity, migration rates, and vegetation conditions since the 1800s. Most quantitative information is for the period between 1940 and 2000. The decrease in sinuosity since 1940 for nearly all the unconfined reaches resulted partly from decreased migration rates, but mostly from several cutoffs and avulsions formed between 1940 and 1975. The river shortening and steepening possibly resulted from (1) flood-plain confinement by levees, dikes, roads, and railroads leading to deeper and faster overbank flow, thereby promoting erosion of new flood-plain channels; and (2) flood-plain disturbances such as trails, ditches, and vegetation manipulation or eradication that locally concentrated overbank flow and decreased surface resistance to channel erosion. The most evident vegetation change has been the loss of short woody vegetation adjacent to the river channels: only one-half the near-channel area covered by short woody vegetation in 1940 was similarly covered in 2000. Woody vegetation removal in the 1950s and 1960s and continuing grazing and trampling by livestock probably are the main reasons for the decrease in short woody vegetation from the dense riparian corridors of willows (Salix sp.) and other riparian shrubs noted in the early 20th century. The alluvial corridor of the South Fork Sprague River, compared to other Sprague River Basin rivers, has been the most substantially transformed since first historical observations. The present channel is incised, straightened, and separated from the rarely inundated flood plain by levees. Despite these effects of human disturbances, many of the fundamental physical processes forming the Sprague River fluvial systems over the last several thousand years still function. In particular, flows are unregulated, sediment transport processes are active, and overbank flooding allows for floodplain deposition and erosion. Therefore, restoration of many of the native physical conditions and processes is possible without substantial physical manipulation of current conditions for much of the Sprague River study area. An exception is the South Fork Sprague River, where historical trends are not likely to reverse until it attains a more natural channel and flood-plain geometry and the channel aggrades to the extent that overbank flow becomes common.
Download or read book Alluvial Fan Flooding written by National Research Council and published by National Academies Press. This book was released on 1996-10-07 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: Alluvial fans are gently sloping, fan-shaped landforms common at the base of mountain ranges in arid and semiarid regions such as the American West. Floods on alluvial fans, although characterized by relatively shallow depths, strike with little if any warning, can travel at extremely high velocities, and can carry a tremendous amount of sediment and debris. Such flooding presents unique problems to federal and state planners in terms of quantifying flood hazards, predicting the magnitude at which those hazards can be expected at a particular location, and devising reliable mitigation strategies. Alluvial Fan Flooding attempts to improve our capability to determine whether areas are subject to alluvial fan flooding and provides a practical perspective on how to make such a determination. The book presents criteria for determining whether an area is subject to flooding and provides examples of applying the definition and criteria to real situations in Arizona, California, New Mexico, Utah, and elsewhere. The volume also contains recommendations for the Federal Emergency Management Agency, which is primarily responsible for floodplain mapping, and for state and local decisionmakers involved in flood hazard reduction.
Download or read book Landscapes and Landforms of Turkey written by Catherine Kuzucuoğlu and published by Springer. This book was released on 2019-01-08 with total page 632 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book on Turkish geomorphology offers location descriptions, based on their dynamics and evolution processes, including hydrology, tectonics, volcanism, slopes, coasts, ice/snow, and wind. It presents landforms as a result of evolution (Quaternary, Holocene, historic) and in relation to the elements determining and/or impacting this evolution (vegetation, soil, hydrology, geology, climate, sea level and human action) as well as the resulting landscapes. Richly illustrated with pictures from each site, including geomorphological maps and sections, it explains the risks associated with the geomorphological dynamics (on local and global scales), natural and/or cultural heritage (archaeology, prehistory, history, architectural specifications adapted to the landscape), as well as challenges for human society (endangered landscape, protection/conservation rules/statutes, posters/paintings.).

This book was released on 2006-11-15 with total page 981 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book brings together eastern and western scholarship on a controversial subject: a catastrophic inundation of the Pontic basin which might have inspired the biblical story of Noah’s flood. In 35 papers, many previously unavailable in English, experts in oceanography, marine geology, paleoclimate, paleoenvironment, archaeology, and linguistic spread offer data and arguments for or against the flood hypothesis. Appendices include 600 radiocarbon dates from the region, obtained by USSR and western labs.
Download or read book Mediterranean Coastal Lagoons written by S. Cataudella and published by Food & Agriculture Organization of the UN (FAO). This book was released on 2015 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The Mediterranean region hosts around 400 coastal lagoons, covering a surface of over 641 000 ha differing in both their typology and use. Fisheries and various forms of aquaculture have been traditionally carried out in Mediterranean coastal lagoons since ancient times and are part of the cultural heritage of the region. Traditional lagoon management linked to extensive aquaculture and fish harvesting has certainly contributed, over time, to preserve these peculiar ecosystems, although much of the coastal lagoon areas have progressively disappeared due to land reclamation and other uses. Recently, coastal lagoons have become a relevant environmental concern: land claiming, pollution and the lack of management, among other factors, have strongly modified both the structure and functioning of these sensitive coastal ecosystems. In particular, the management of traditional aquaculture and capture fisheries activities has been identified as the main instrument to maintain lagoons' ecological features and to prevent the degradation of their sensitive habitats, both from an environmental and socioeconomic point of view. To guarantee the sustainability of aquaculture and capture fisheries in lagoons, proper management plans should be established so as to ensure the preservation of both biodiversity and local knowledge. This should also be considered as a fundamental pillar for any programme aiming at the preservation and restoration of lagoons' environment."--Publisher's description.

Download or read book Desert Truffles written by Varda Kagan-Zur and published by Springer Science & Business Media. This book was released on 2013-10-30 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: Desert truffles are found in every known desert, irrespective of the habitat – cool or hot, loamy or acidic, sandy or heavy soil – the only common condition seems to be a limited supply of water. In contrast to ‘true’ truffles, desert truffles have evolved over time in different families, mainly within the order Pezizales. While in some arid areas, desert truffles have been traditionally used as food, in most regions interest has only recently been increasing, and truffles are now treasured for their nutritional value, as an income source and for research. This volume gives a comprehensive overview of the phylogeny, biology, mycorrhizal association, and distribution of desert truffles, their use, biochemical and medicinal properties, as well as their domestication and cultivation.

Download or read book Soils of Georgia written by Tengiz F. Urushadze and published by Nova Science Publishers. This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes a wide range of soils, from the humid subtropical coast of the Black Sea to the frozen peaks of the High Caucasus with more than 5.000 meters above sea level and from extremely humid areas in the West to dry, semi-desert regions in the East, with an enormous variety of rock parent materials, a very accentuated hydrology and a topography, ranging from large plains, hilly regions to steep and strongly dissected slopes and gorges in the High and Lower Caucasus. There is no other country in the world the size of Georgia with such a variety of soil forming conditions and soils. Therefore, V V Dokuchaev, one of the founders of the genetic soil classification, called Georgia an "Open-Air Museum of Soils". The book is subdivided into 6 chapters. In Chapter 1, the physiography of Georgia and the factors of soil formation such as topography, geology, climate and vegetation are described, followed by Chapter 2, with the detailed description of 21 soil groups, their morphological, physical and chemical characteristics, their many different subtypes and variations, and their ecology, based on 72 tables, 25 figures and 20 photos. Moreover, the location of each soil and its surface in % of the total surface of Georgia are explained, including the history of their discovery and investigation together with the relevant literature. In Chapter 3, the overall ecological conditions, especially problems of soil erosion by water and wind and the soil contamination by heavy metals and radionuclides are described, followed by Chapter 4 with an explanation of the soil use, based on physical and chemical soil characteristics. Two further chapters with references and soil photos conclude the book, which is written by Professor Tengiz F Urushadze from the Agricultural University of Georgia in Tbilisi and Professor Winfried E H Blum from the University of Natural Resources and Life Sciences (BOKU) in Vienna, Austria.
