Book excerpt: The changing focus and approach of geomorphic research suggests that the time is opportune for a summary of the state of discipline. The number of peer-reviewed papers published in geomorphic journals has grown steadily for more than two decades and, more importantly, the diversity of authors with respect to geographic location and disciplinary background (geography, geology, ecology, civil engineering, computer science, geographic information science, and others) has expanded dramatically. As more good minds are drawn to geomorphology, and the breadth of the peer-reviewed literature grows, an effective summary of contemporary geomorphic knowledge becomes increasingly difficult. The fourteen volumes of this Treatise on Geomorphology will provide an important reference for users from undergraduate students looking for term paper topics, to graduate students starting a literature review for their thesis work, and professionals seeking a concise summary of a particular topic. Information on the historical development of diverse topics within geomorphology provides context for ongoing research; discussion of research strategies, equipment, and field methods, laboratory experiments, and numerical simulations reflect the multiple approaches to understanding Earth’s surfaces; and summaries of outstanding research questions highlight future challenges and suggest productive new avenues for research. Our future ability to adapt to geomorphic changes in the critical zone very much hinges upon how well landform scientists comprehend the dynamics of Earth’s diverse surfaces. This Treatise on Geomorphology provides a useful synthesis of the state of the discipline, as well as highlighting productive research directions, that Educators and students/researchers will find useful. Geomorphology has advanced greatly in the last 10 years to become a very interdisciplinary field. Undergraduate students looking for term paper topics, to graduate students starting a literature review for their thesis work, and professionals seeking a concise summary of a particular topic will find the answers they need in this broad reference work which has been designed and written to accommodate their diverse backgrounds and levels of understanding Editor-in-Chief, Prof. J. F. Shroder of the University of Nebraska at Omaha, is past president of the QG&G section of the Geological Society of America and present Trustee of the GSA Foundation, while being well respected in the geomorphology research community and having won numerous awards in the field. A host of noted international geomorphologists have contributed state-of-the-art chapters to the work. Readers can be guaranteed that every chapter in this extensive work has been critically reviewed for consistency and accuracy by the World expert Volume Editors and by the Editor-in-Chief himself No other reference work exists in the area of Geomorphology that offers the breadth and depth of information contained in this 14-volume masterpiece. From the foundations and history of geomorphology through to geomorphological innovations and computer modelling, and the past and future states of landform science, no "stone" has been left unturned!

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.
Download or read book Numerical Study of Two phase Turbulent Flow in Hydraulic Jumps written by Seyedpouyan Ahmadpanah and published by . This book was released on 2017 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydraulic jump is a rapidly varied flow phenomenon that the flow changes suddenly from supercritical to subcritical. Hydraulic jumps are frequently observed to exist in natural river channels, streams, coastal water, and man-made water conveyance systems. Because of a sudden transition of flow regime, hydraulic jumps result in complex flow structures, strong turbulence, and air entrainment. Accordingly, they are two-phase flow, with air being the gas phase and water being the liquid phase. Consequences of the occurrence of hydraulic jumps include: unwanted fluctuations in the water surface with unstable waves and rollers, undesirable erosion of channel sidewalls and channel bottom, and reduced efficiency for water conveyance systems. Thus, it is important to study various aspects of the phenomenon.So far, knowledge of the phenomenon is incomplete. The main objective of this research is to improve our understanding of the complex flow structures and distributions of air entrainment in a hydraulic jump. Previously, both experimental and computational studies of the phenomenon have typically suffered a scale problem. The dimensions of the setup being used were unrealistically too small.In this research, we took the computational fluid dynamics (CFD) approach, and simulated hydraulic jumps at relatively large and practical dimensions. This would help reduce artificial scale effects on the results. On the basis of Reynolds averaged continuity and momentum equations, CFD simulations of hydraulic jumps were performed for four different cases in terms of the approach flow Froude number Fr1, ranging from 3.1 to 5.1. The Reynolds number is high (between 577662 and 950347), which ensures turbulent flow conditions. The CFD model channel is discretized into 2,131,200 cells. The mesh has nearly uniform structures, with fine spatial resolutions of 2.5 mm. The volume of fluid method provides tracking of the free surface. The standard k-f turbulence model provides turbulence closure.For each of the simulation cases, we carried out analyses of time-averaged air volume fraction, time-averaged velocity, time- and depth-averaged (or double averaged) air volume fraction at a series of locations along the length of the model channel (Note that the terms air volume fraction and void fraction are used interchangeably in this thesis). We compared the CFD predictions of air volume fraction with available laboratory measurements. It is important to note that these measurements were made from laboratory experiments that corresponded to essentially the same values of Fr as this CFD study, but used a channel of smaller dimensions, in comparison to the CFD model channel. The CFD results of time-averaged air volume fraction are reasonable, when compared to the experimental data, except for the simulation case with Fr1 = 3.8. For all the four simulation cases, the predicted variations in air volume fraction show a trend in consistency with the experimental results. For the three simulation cases (with Fr1 = 3.1, 3.8 and 4.4), the time-averaged air volume fraction in the hydraulic jumps is larger at higher Reynolds number. However, for the simulation case with Fr1 = 5.1, it is smaller at higher Reynolds number. This implies that the amount of air being entrained into a hydraulic jump depends on not only Fr1 but also the depth of the approach flow. In future studies of the hydraulic jump phenomenon, one should consider using approach flow of realistically large dimensions at various values of Fr1, for realistic predictions of air entrainment in hydraulic jump rollers.

Available in PDF, EPUB and Kindle. Book excerpt: Filling a niche in the geomorphology teaching market, this introductory book is built around a 12 week course in fluvial geomorphology. ‘Reading the landscape’ entails making sense of what a riverscape looks like, how it works, how it has evolved over time, and how alterations to one part of a catchment may have secondary consequences elsewhere, over different timeframes. These place-based field analyses are framed within their topographic, climatic and environmental context. Issues and principles presented in the first part of this book provide foundational understandings that underpin the approach to reading the landscape that is presented in the second half of the book. In reading the landscape, detective-style investigations and interpretations are tied to theoretical and conceptual principles to generate catchment-specific analyses of river character, behaviour and evolution, including responses to human disturbance. This book has been constructed as an introductory text on river landscapes, providing a bridge and/or companion to quantitatively-framed or modelled approaches to landscape analysis that are addressed elsewhere. Key principles outlined in the book emphasise the importance of complexity, contingency and emergence in interpreting the character, behaviour and evolution of any given system. The target audience is second and third year undergraduate students in geomorphology, hydrology, earth science and environmental science, as well as river practitioners who use geomorphic understandings to guide scientific and/or management applications. The primary focus of Kirstie and Gary’s research and teaching entails the use of geomorphic principles as a tool with which to develop coherent scientific understandings of river systems, and the application of these understandings in management practice. Kirstie and Gary are co-developers of the River Styles® Framework and Short Course that is widely used in river management, decision-making and training.

Download or read book Studies on Hydraulic Jump in Prismatic and Non Prismatic Channels written by Sumit Gandhi and published by LAP Lambert Academic Publishing. This book was released on 2011-09 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydraulic jump is most frequently encountered features of RVF in open channels as the supercritical flow changes to subcritical flow; during this phenomenon air is entrained because of the breaking of number of wavelets on the surface and get released in the form of air bubbles. Compared to prismatic, non-prismatic channels with appurtenances not only modify the hydraulic jump characteristics but also affect significantly the formation of symmetric flows downstream of the channel. Moreover, non-prismatic channels with baffle blocks & sill arrangements are useful to control the hydraulic jump in stilling basins when there is deficiency of tail water depth and the places where there is design constraints in order to reduce the basin length. It is also useful in the situations where it is impossible to depress the basin floor because of difficulties in excavation; a lateral expansion remains the only option for the required dissipation of energy through formation of hydraulic jump. For safe and economical design of stilling basin in the downstream of dams the characteristics of hydraulic jumps, such as length, toe position and symmetry should be predicted as accurately as possible.
