Available in PDF, EPUB and Kindle. Book excerpt: Fluvial adjustment to base level change has its roots in the fundamental concepts of geomorphology. This thesis explores the rate of erosion and sedimentation on the Colorado and Dirty Devil rivers and North Wash Creek under the current base level changes related to the drawdown conditions of Lake Powell. Through cross section and long profile resurveys, the current state of each system is captured and added to the historic record of sedimentation in Lake Powell. All three systems are generally forming narrow and deep incised channels driven by the rapid rate of base level fall. Cross sections that deviate from this are due to site-specific factors, such as channel armoring, the presence of local base levels, or bedrock canyon width in relation to active channel width. In all systems, sediment is being transported through the establishing fluvial regime and is deposited at or below the new base level. This has caused rapid downstream progradation of each delta front. The volume of sediment accumulation and erosion and rates through time are calculated for each system. Deposit volume is proportional to each systems drainage basin area, as are the rates and magnitudes of deposition and erosion. The percentage of sediment eroded versus deposited shows an inverse relationship, with North Wash eroding the greatest percentage of its delta. Field observations and repeat photography on the distribution, orientation, and activity of lateral slumping and mud cracks identify that thick beds of fine-grained and cohesive silts and clays are necessary for these features to form. These features act to destabilize sediment and, in the case of bank failure, deliver it directly to the channel.

Book excerpt: Much of the final shaping of the global landscape is accomplished by incision of river networks. The base-level is a principle determinate controlling the global relief by processes of erosion and aggradation. In the populated world, entrenchments triggered by base-level changes may become devastating events, damaging agricultural lands, undercutting bridges and destroying roads. The aim of this book, as a chapter in fluviomorphology, is to present the base-level control when active in the continental interior, unrelated to marine base-level fluctuations along the continental margins nor to sequence stratigraphic tract models in Exxon sequence stratigraphic sense. The focus is on the morphology and the gross trends of the processes controlling channel evolution through transient signals initiated by base-level changes and communicated upstream through the drainage network. The book brings together principles and conclusions gained by field work, by laboratory studies and by models, based on the widely scattered literature. The chapters include presentation of different types of base-levels, discussing the constraints of their altitude, the degradation and aggradation responses, the temporal and spatial trends along the channel network, the controlling factors, the knickpoint transient retreat process and its rates. Special emphasis is given to the Dead Sea Rift following its extreme base-level conditions which make it a unique field laboratory. This book is relevant to students in earth sciences as well as to planners, hydrologists and engineers dealing with geomorphology and surface drainage.

Available in PDF, EPUB and Kindle. Book excerpt: This book addresses the various factors affecting fluvial systems, the processes governing them, system responses arising from human-nature interventions, and geospatial and geo-ecological modeling to understand system behaviour better and restore degraded ecosystems around the globe. Thanks to their hydrological and agro-ecological advantages, humans have settled along riverbanks since the dawn of civilization. Thus, the ancient "ecumene" (settlements) were located near major rivers worldwide. This legacy of river-based civilizations continues to this day in many forms. However, in the course of the 'Anthropocene' era, countless fluvial systems have been altered by human interventions in the form of large-scale dams and barrages, changes in land use and land cover, road-stream crossings, mining of sand and gravel, mushrooming of brickfield, expansion of modern agriculture, industrial growth, and urbanization. Thus, the present-day development pattern threatens fluvial systems, especially riverine morphology and ecosystems. In brief, human-induced morphological changes, water pollution, eutrophication, and related damages to aquatic organisms are the major threats to fluvial systems. Thus, maintaining the 'environmental flow' of the world's major rivers to preserve the proper functioning of riverine ecosystems and promote sustainable development is a global challenge.

Available in PDF, EPUB and Kindle. Book excerpt: For several decades Peter Friend has been one of the leading figures in sedimentary geology and throughout that time he has helped scores of other people by supervising doctoral students, collaborating with colleagues, especially in developing countries, and selflessly sharing ideas with fellow geologists. This collection of papers is a survey of the research frontier in basin dynamics, a field Peter Friend helped initiate, and a token of thanks from people who have benefited from an association with Peter during their careers. The papers in this book fall into four themes - Tectonics and sedimentation, Landscape evolution and provenance, Depositional systems and Fluvial sedimentation - which reflect Peter's research interests and are all important areas of current research in sedimentary geology. There are both case studies and review articles on these themes which reflect recent work, but the collection can also be considered to be a 'sampler' of sedimentary geology for anyone with broad interests in the Earth sciences.

Book excerpt: Nonrenewable energy resources, comprising fossil fuels and uranium, are not ran domly distributed within the Earth's crust. They formed in response to a complex array of geologic controls, notably the genesis of the sedimentary rocks that host most commercial energy resources. It is this genetic relationship between economic re sources and environment that forms the basis for this book. Our grouping of petro leum, coal, uranium, and ground water may appear to be incongruous or artificial. But our basic premise is that these ostensibly disparate resources share common genetic attributes and that the sedimentological principles governing their natural distributions and influencing their recovery are fundamentally similar. Our combined careers have focused on these four resources, and our experiences in projects worldwide reveal that certain recurring geologic factors are important in controlling the distribution of com mercial accumulations and subsurface fluid flow. These critical factors include the shape and stability of the receiving basin, the major depositional elements and their internal detail, and the modifications during burial that are brought about in these sediments by pressure, circulating fluids, heating, and chemical reaction. Since the first edition of this book in 1983, there has been a quantum leap in the volume of literature devoted to genetic stratigraphy and refinement of sedimentologi cal principles and a commensurate increase in the application of these concepts to resource exploration and development.

Available in PDF, EPUB and Kindle. Book excerpt: Rivers have played an extraordinarily important role in creating the world in which we live. They create landscapes and provide water to people, plants and animals, nourishing both town and country. The flow of rivers has enthused poets and painters, explorers and pilgrims. Rivers have acted as cradles for civilization and agents of disaster; a river may be a barrier or a highway, it can bear trade and sediment, culture and conflict. A river may inspire or it may terrify. This Very Short Introduction is a celebration of rivers in all their diversity. Nick Middleton covers a wide and eclectic range of river-based themes, from physical geography to mythology, to industrial history and literary criticism. Worshipped and revered, respected and feared, rivers reflect both the natural and social history of our planet. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

Available in PDF, EPUB and Kindle. Book excerpt: Rivers are important agents of change that shape the Earth's surface and evolve through time in response to fluctuations in climate and other environmental conditions. They are fundamental in landscape development, and essential for water supply, irrigation, and transportation. This book provides a comprehensive overview of the geomorphological processes that shape rivers and that produce change in the form of rivers. It explores how the dynamics of rivers are being affected by anthropogenic change, including climate change, dam construction, and modification of rivers for flood control and land drainage. It discusses how concern about environmental degradation of rivers has led to the emergence of management strategies to restore and naturalize these systems, and how river management techniques work best when coordinated with the natural dynamics of rivers. This textbook provides an excellent resource for students, researchers, and professionals in fluvial geomorphology, hydrology, river science, and environmental policy.

This book was released on 2014-07-18 with total page 710 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Norwegian Continental Shelf (NCS), focus of this special publication, is a prolific hydrocarbon region and both exploration and production activity remains high to this day with a positive production outlook. A key element today and in the future is to couple technological developments to improving our understanding of specific geological situations. The theme of the publication reflects the immense efforts made by all industry operators and their academic partners on the NCS to understand in detail the structural setting, sedimentology and stratigraphy of the hydrocarbon bearing units and their source and seal. The papers cover a wide spectrum of depositional environments ranging from alluvial fans to deepwater fans, in almost every climate type from arid through humid to glacial, and in a variety of tectonic settings. Special attention is given to the integration of both analogue studies and process-based models with the insights gained from extensive subsurface datasets.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides an appealing and informative overview of the outstanding landforms and landscapes of Scotland. Scotland is internationally renowned for the diversity of its geology, landforms and landscapes. The rock record spans most of geological time, from the Archaean to the Palaeogene, and represents the outcome of tectonic plate movements, associated geological processes, and sea-level and climate changes. Scotland incorporates primeval gneiss landscapes, the deeply eroded roots of the Caledonian mountain chain, landscapes of extensional tectonics and rifting, and eroded remnants of volcanic complexes that were active when the North Atlantic Ocean opened during the Palaeogene. The present relief reflects uplift and deep weathering during the Cenozoic, strongly modified during successive episodes of Pleistocene glaciation. This striking geodiversity is captured in this book through 29 chapters devoted to the evolution of Scotland’s scenery and locations of outstanding geomorphological significance, including ancient palaeosurfaces, landscapes of glacial erosion and deposition, evidence of postglacial landscape modification by landslides, rivers and wind, and coastal geomorphology. Dedicated chapters focus on Ice Age Scotland and the associated landscapes, which range from alpine-type mountains and areas of selective glacial erosion to ice-moulded and drift-covered lowlands, and incorporate accounts of internationally renowned sites such as the ‘Parallel Roads’ of Glen Roy, the Cairngorm Mountains and the inselbergs of Assynt. Other chapters consider the record of postglacial rock-slope failures, such as the famous landslides of Trotternish on Skye, and the record of fluvial changes since deglaciation. The sea-level history of Scotland is addressed in terms of its raised and submerged shorelines, while several chapters discuss the contrasting coastal landscapes, which range from the spectacular sea cliffs of Shetland and Orkney to the beaches and dunes of eastern Scotland. The role of geoconservation in preserving Scotland’s outstanding geomorphological heritage is outlined in the final chapter. The book offers an up-to-date and richly illustrated reference guide for geomorphologists, other Earth scientists, geographers, conservationists, and all those interested in geology, physical geography, geomorphology, geotourism, geoheritage and environmental protection.
