Book Synopsis River Meanders--theory of Minimum Variance by : Walter Basil Langbein
Download or read book River Meanders--theory of Minimum Variance written by Walter Basil Langbein and published by . This book was released on 1966 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: The geometry of a meander is that of a random walk whose most frequent form minimizes the sum of the squares of the changes in direction in each unit length. Changes in direction closely approximate a sine function of channel distance. Depth, velocity, and slope are adjusted so as to decrease the variance of shear and the friction factor in a meander over that in an otherwise comparable straight reach of the same river.
Book Synopsis Theoretical Morphodynamics: River Meandering by : Giovanni Seminara
Download or read book Theoretical Morphodynamics: River Meandering written by Giovanni Seminara and published by Firenze University Press. This book was released on 2024-04-05 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph discusses the mechanics of Meandering Rivers with the help of the mathematical and modeling tools built up in the previous monograph of the same Authors (monograph 1 of the present series). After introducing the reader to the ubiquitous character of meandering streams, we discuss the hydrodynamics of curved channels with fixed beds and banks. Next, we extend the analysis to account for the mobile character of the bed and show that it gives rise to the alternate sequence of riffles and pools that characterize river meanders. Allowing for the erodible character of the river banks then allows to build up a rational theory of meander formation able to explain most of the features observed in nature: meander growth, migration, skewing, multiple loops, cutoffs and meander belts.

Book Synopsis A Systems Approach for River and River Basin Restoration by : Theodore Endreny
Download or read book A Systems Approach for River and River Basin Restoration written by Theodore Endreny and published by MDPI. This book was released on 2021-05-27 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Communities increasingly find that the water quality, water levels, or some other resource indicator in their river basins do not meet their expectations. This discrepancy between the desired and actual state of the resource leads to efforts in river basin restoration. River basins are complex systems, and too often, restoration efforts are ineffective due to a lack of understanding of the purpose of the system, defined by the system structure and function. The river basin structure includes stocks (e.g., water level or quality), inflows (e.g., precipitation or fertilization), outflows (e.g., evaporation or runoff), and positive and negative feedback loops with delays in responsiveness, all of which function to change or stabilize the state of the system (e.g., the stock of interest, such as water level or quality). External drivers on this structure, together with goals and rules, contribute to how a river basin functions. This book reviews several new research projects to identify and rank the twelve most effective leverage points to address discrepancies between the desired and actual state of the river basin system. This book demonstrates that river basin restoration is most likely to succeed when we change paradigms rather than try to change the system elements, as the paradigm will establish the system goals, structure, rules, delays, and parameters.
Book Synopsis River and Coastal Engineering by : Ramakar Jha
Download or read book River and Coastal Engineering written by Ramakar Jha and published by Springer Nature. This book was released on 2022-08-03 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with important topics of current interest, such as climate change, floods, drought, and hydrological extremes. The impact of climate change on water resources is drawing worldwide attention in these days; water resources in many countries are already stressed and climate change along with burgeoning population, rising standard of living, and increasing demand are adding to the stress. Further, river basins are becoming less resilient to climatic vagaries. Fundamental to addressing these issues is hydrological modelling which is covered in these books. Further, integrated water resources management is vital to ensure water and food security. Integral to the management is groundwater and solute transport. The books encompass tools that will be useful to mitigate the adverse consequences of natural disasters. This book is useful for those working in river and coastal engineering. River Engineering is important for fluvial hydraulics, sediment transport, morphometry, desilting, trap efficiency, silting and desilting process. Coastal engineering includes storm surge forecast, optimization of harbour, wave modelling, and shoreline changes.

Book Synopsis Geomorphology by : Richard J. Chorley
Download or read book Geomorphology written by Richard J. Chorley and published by Routledge. This book was released on 2019-04-10 with total page 1174 pages. Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 1984. This major text covers the whole discipline of geomorphology, presenting a clear and comprehensive overview of the field, drawing on the full range of modern research. Landforms and their formative processes are treated on a broad spectrum of spatial scales, and examples are drawn from the major geological, climatic and biotic environments. The book is divided conveniently into some 170 clearly defined sections to allow readers to make the most efficient use of those parts of the text relevant to their particular needs. After introducing the basic concepts such as systems analysis, morphologic and cascading systems, the historical-evolutionary approach and process-response geomorphology, the book moves on to the geological background to geomorphology and then the extensive third part deals with the geomorphic processes and responding landforms. Part four examines climatic geomorphology and the appendix touches on applied geomorphology, especially fluvial processes.

Available in PDF, EPUB and Kindle. Book excerpt: Conference Proceedings of Euromech 192: Transport of suspended solids in open channels, Munich, Neubiberg, 11-15 June 1985. Rapid growth in water requirements makes it necessary to increase the amount of water drawn from rivers. The dams necessary for capturing river water have to be built to resist damage when large floods occur, and an idea of the possible destructive power of floods is given by the front cover photograph.

Book Synopsis River Ecology and Management by : Robert Naiman
Download or read book River Ecology and Management written by Robert Naiman and published by Springer Science & Business Media. This book was released on 2001-02-16 with total page 734 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the vast expanses of natural forests and the great populations of salmonids are harvested to support a rapidly expanding human population, the need to understand streams as ecological systems and to manage them effectively becomes increasingly urgent. The unfortunate legacy of such natural resource exploitation is well documented. For several decades the Pacific coastal ecoregion of North America has served as a natural laboratory for scientific and managerial advancements in stream ecology, and much has been learned about how to better integrate ecological processes and characteristics with a human-dominated environment. These in sightful but hard-learned ecological and social lessons are the subject of this book. Integrating land and rivers as interactive components of ecosystems and watersheds has provided the ecological sciences with impor tant theoretical foundations. Even though scientific disciplines have begun to integrate land-based processes with streams and rivers, the institutions and processes charged with managing these systems have not done so successfully. As a result, many of the watersheds of the Pacific coastal ecoregion no longer support natural settings for environmental processes or the valuable natural resources those processes create. An important role for scientists, educators, and decision makers is to make the integration between ecology and con sumptive uses more widely understood, as well as useful for effective management.
