Modeling and Practice of Erosion and Sediment Transport under Change


Book Description

Climate and anthropogenic changes impact the conditions of erosion and sediment transport in rivers. Rainfall variability and, in many places, the increase of rainfall intensity have a direct impact on rainfall erosivity. Increasing changes in demography have led to the acceleration of land cover changes in natural areas, as well as in cultivated areas, and, sometimes, in degraded areas and desertified landscapes. These anthropogenized landscapes are more sensitive to erosion. On the other hand, the increase in the number of dams in watersheds traps a great portion of sediment fluxes, which do not reach the sea in the same amount, nor at the same quality, with consequences on coastal geomorphodynamics. This book is dedicated to studies on sediment fluxes from continental areas to coastal areas, as well as observation, modeling, and impact analysis at different scales from watershed slopes to the outputs of large river basins. This book is concentrated on a number of keywords: “erosion” and “sediment transport”, “model” and “practice”, and “change”. The keywords are briefly discussed with respect to the relevant literature. The contributions in this book address observations and models based on laboratory and field data, allowing researchers to make use of such resources in practice under changing conditions.




Bayou Farewell


Book Description

The Cajun coast of Louisiana is home to a way of life as unique, complex, and beautiful as the terrain itself. As award-winning travel writer Mike Tidwell journeys through the bayou, he introduces us to the food and the language, the shrimp fisherman, the Houma Indians, and the rich cultural history that makes it unlike any other place in the world. But seeing the skeletons of oak trees killed by the salinity of the groundwater, and whole cemeteries sinking into swampland and out of sight, Tidwell also explains why each introduction may be a farewell—as the storied Louisiana coast steadily erodes into the Gulf of Mexico. Part travelogue, part environmental exposé, Bayou Farewell is the richly evocative chronicle of the author's travels through a world that is vanishing before our eyes.




Fundamentals of Geomorphology


Book Description

This extensively revised, restructured, and updated edition continues to present an engaging and comprehensive introduction to the subject, exploring the world’s landforms from a broad systems perspective. It covers the basics of Earth surface forms and processes, while reflecting on the latest developments in the field. Fundamentals of Geomorphology begins with a consideration of the nature of geomorphology, process and form, history, and geomorphic systems, and moves on to discuss: structure: structural landforms associated with plate tectonics and those associated with volcanoes, impact craters, and folds, faults, and joints process and form: landforms resulting from, or influenced by, the exogenic agencies of weathering, running water, flowing ice and meltwater, ground ice and frost, the wind, and the sea; landforms developed on limestone; and landscape evolution, a discussion of ancient landforms, including palaeosurfaces, stagnant landscape features, and evolutionary aspects of landscape change. This third edition has been fully updated to include a clearer initial explanation of the nature of geomorphology, of land surface process and form, and of land-surface change over different timescales. The text has been restructured to incorporate information on geomorphic materials and processes at more suitable points in the book. Finally, historical geomorphology has been integrated throughout the text to reflect the importance of history in all aspects of geomorphology. Fundamentals of Geomorphology provides a stimulating and innovative perspective on the key topics and debates within the field of geomorphology. Written in an accessible and lively manner, it includes guides to further reading, chapter summaries, and an extensive glossary of key terms. The book is also illustrated throughout with over 200 informative diagrams and attractive photographs, all in colour.




Urban Stormwater Management in the United States


Book Description

The rapid conversion of land to urban and suburban areas has profoundly altered how water flows during and following storm events, putting higher volumes of water and more pollutants into the nation's rivers, lakes, and estuaries. These changes have degraded water quality and habitat in virtually every urban stream system. The Clean Water Act regulatory framework for addressing sewage and industrial wastes is not well suited to the more difficult problem of stormwater discharges. This book calls for an entirely new permitting structure that would put authority and accountability for stormwater discharges at the municipal level. A number of additional actions, such as conserving natural areas, reducing hard surface cover (e.g., roads and parking lots), and retrofitting urban areas with features that hold and treat stormwater, are recommended.




Geomorphology


Book Description

This systematic, non-mathematical analysis of landforms of the late Cenozoic Era covers the constructional processes of tectonism and volcanism and the erosional processes of weathering, fluvial erosion, glaciers, wind, and waves.




The Living Waters of Texas


Book Description

In ten impassioned essays, veteran Texas environmental advocates and conservation professionals step outside their roles as lawyers, lobbyists, administrators, consultants, and researchers to write about water. Their personal stories of what the springs, rivers, bottomlands, bayous, marshes, estuaries, bays, lakes, and reservoirs mean to them and to our state come alive in the landscape photography of Charles Kruvand. Allied with the Texas Living Waters Project (a joint education and policy initiative of the Lone Star Chapter of the Sierra Club, the National Wildlife Federation, and the Environmental Defense Fund, among others), editor Ken Kramer joins his fellow activists in a call to keep rivers flowing, to protect wildlife habitat, and to save tax dollars by using water efficiently and sustainability.

Soil Erosion and Carbon Dynamics


Book Description

The most complete, nonpartisan source of information on this hot agronomic topic available today, this book brings together a diverse group of papers and data to resolve the debate between sedimentologists and soil scientists and agronomists over whether the effects of soil erosion on carbon and atmospheric CO2 is beneficial or destructive. Divided into four sections, it offers data on how soil erosion affects soil, water, and air quality. Topics include mineralization rate, inundation, sediment deposition, and global warming potential, as well as carbon dioxide, methane, and nitrous oxide emissions, and the implications of soil erosion on the global carbon cycle and carbon budget.




Climate Change and Indigenous Peoples in the United States


Book Description

With a long history and deep connection to the Earth’s resources, indigenous peoples have an intimate understanding and ability to observe the impacts linked to climate change. Traditional ecological knowledge and tribal experience play a key role in developing future scientific solutions for adaptation to the impacts. The book explores climate-related issues for indigenous communities in the United States, including loss of traditional knowledge, forests and ecosystems, food security and traditional foods, as well as water, Arctic sea ice loss, permafrost thaw and relocation. The book also highlights how tribal communities and programs are responding to the changing environments. Fifty authors from tribal communities, academia, government agencies and NGOs contributed to the book. Previously published in Climatic Change, Volume 120, Issue 3, 2013.




Erosion and Sedimentation

The structure of the first edition is essentially unchanged, but all the chapters have been updated, with several chapters reworked and expanded significantly. Examples of the new additions include the concept of added mass, the Modified Einstein Procedure, sediment transport by size fractions, sediment transport of sediment mixtures, and new solutions to the Einstein Integrals. Many new examples and exercises have been added. Erosion and Sedimentation is an essential textbook on the topic for students in civil and environmental engineering and the geosciences, and also as a handbook for researchers and professionals in engineering, the geosciences and the water sciences.




Ecology of a Cracker Childhood


Book Description

From the memories of a childhood marked by extreme poverty, mental illness, and restrictive fundamentalist Christian rules, Janisse Ray crafted a “heartfelt and refreshing” (New York Times) memoir that has inspired thousands to embrace their beginnings, no matter how humble, and to fight for the places they love. This new edition updates and contextualizes the story for a new generation and a wider audience desperately searching for stories of empowerment and hope. Ray grew up in a junkyard along U.S. Highway 1, hidden from Florida-bound travelers by hulks of old cars. In language at once colloquial, elegiac, and informative, Ray redeems her home and her people, while also cataloging the source of her childhood hope: the Edenic longleaf pine forests, where orchids grow amid wiregrass at the feet of widely spaced, lofty trees. Today, the forests exist in fragments, cherished and threatened, and the South of her youth is gradually being overtaken by golf courses and suburban development. A contemporary classic, Ecology of a Cracker Childhood is a clarion call to protect the cultures and ecologies of every childhood.
