This book was released on 2017-10-28 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Water Retention of Granitic Soils in the Idaho Batholith Tables and equations for the two retention models are presented in the Appendix. The final models were subsequently adjusted by least squares to two new data sets of geographically diverse soils from the Idaho Batholith. The ad justed retention models operate well for predicting water retention at both energy levels. The value of the models is discussed in light of these findings. Knowledge of the water retention properties of soils is an important facet of the hydrologic data necessary for wise management of forested lands. Management decisions that are based on soil water retention data include: types and expected rates of timber regeneration; potential for erosion and sediment production; changes in water yields following vegetative manipulation; design and location of roads; and a myriad of ecological factors.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Soil and Bedrock Properties: Weathering and Alteration Products and Processes in the Idaho Batholith The mechanical properties of granitic rock and the derived weathered materials are intimately related to slope stability in the Idaho batholith. Processes and products of physical weathering, chemical weathering, and hydrothermal alteration of batholithic rocks can be ranked in terms of degree of weathering and used to predict slope stability. Bulk density, hardness, unconfined compressive strength, and velocity of sonic wave transmission of weathered rock samples are all strongly correlated with weathering properties. Following subtle, initial hydrolysis of biotites, physical weathering processes are dominant in the breakdown of rock to grus at and near the soil surface. Grus is often formed with little alteration of biotites and feldspars to secondary minerals or amorphous oxides of silicon, aluminum, and iron. Bedrock buried at depths below the rooting zone is subject to intense chemical weathering and mineral alteration. The degree to which chemical weathering processes can proceed is related to the inherent slope stability of the site. On gentle slopes with low erosion rates, chemical weathering can advance to a point where the weathered product consists of quartz grains embedded in a matrix of clays and crystalline and amorphous oxides of silicon, aluminum, and iron.

This book was released on 2017-11-16 with total page 704 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Deep-Rooted Plants for Erosion Control on Granitic Road Fills in the Idaho Batholith In general, the erosion potential probably is increased more on the fill portions of a road than on the cut portions. Hydrologic analysis of the Zena Creek logging study area conducted by the Payette National Forest in 1966 showed that surface erosion on fills was an estimated times that on road cuts. Evaluations also showed that material moved by mass erosion (landslides) amounted to almost as much as that resulting from surface erosion. Most landslides in the Zena Creek area occurred in the fill portions of roads. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

This book was released on 2017-10-29 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Investigation of Slope Failures in the Idaho Batholith Because of the increased and justified emphasis upon environmental degradation, proper use of the many millions of acres of forest watersheds requires careful planning. The skills of many disciplines and the combined knowledge that covers all aspects of this complicated ecosystem-the forest - are necessary to assure proper use of forest lands. The silviculturist, ecologist, hydrologist, engineer, and others, must all function as a team to develop and carry out plans for management of forest lands. The Idaho Batholith (fig. 1) is one of the most critical areas as to surface and subsurface stability erosion and landslides) in the Intermountain West; also, this area provides prime spawning and rearing grounds for the Pacific salmon, good timber-producing land and outstanding recreation Opportunities. Two major spawning rivers are the South Fork of the Salmon and the Selway Rivers. The Batholith contains some of the most rugged and pristine scenery in America and includes such well-known areas as the Selway - Bitterroot Wilderness Area, Salmon River Breaks Primitive Area, and the Magruder Corridor. In such areas, those who are charged with the responsibility of multiple use land management face their most serious and complicated challenges. Within the scope of present knowledge and technological skill, proper planning can assure many uses for much of this vast land area. However, much of the Batholith must wait for the results of research to provide additional management guidelines, and it may have to be managed for less than total resource potential if adequate environmental safeguards are to be applied. Considerable attention is currently being directed to the Batholith area. It contains valuable timber reserves as well as other resources which are important to the regional and national economies. However, many of its steep slopes are highly erodible and susceptible to landslides. More specifically, slopes are often greater than 60 percent-and are commonly composed of highly fractured and weathered granite overlain by thin layers of loose, cohesionless soils. Developmental activities, especially roadbuilding, increase the occurrence of landslides and provide large exposed areas from which sediment can readily be removed by normal erosional processes. Initial in creases in production of sediment have been measured and in some instances were more than a thousandfold greater than natural rates from undisturbed terrain.

Download or read book Assembling California written by John McPhee and published by Farrar, Straus and Giroux. This book was released on 2010-04-01 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: At various times in a span of fifteen years, John McPhee made geological field surveys in the company of Eldridge Moores, a tectonicist at the University of California at Davis. The result of these trips is Assembling California, a cross-section in human and geologic time, from Donner Pass in the Sierra Nevada through the golden foothills of the Mother Lode and across the Great Central Valley to the wine country of the Coast Ranges, the rock of San Francisco, and the San Andreas family of faults. The two disparate time scales occasionally intersect—in the gold disruptions of the nineteenth century no less than in the earthquakes of the twentieth—and always with relevance to a newly understood geologic history in which half a dozen large and separate pieces of country are seen to have drifted in from far and near to coalesce as California. McPhee and Moores also journeyed to remote mountains of Arizona and to Cyprus and northern Greece, where rock of the deep-ocean floor has been transported into continental settings, as it has in California. Global in scope and a delight to read, Assembling California is a sweeping narrative of maps in motion, of evolving and dissolving lands.

Download or read book Crossing the Next Meridian written by Charles F. Wilkinson and published by . This book was released on 1992-09 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Crossing the Next Meridian, Wilkinson explains to a general audience some of the core problems that face the American West, both now and in the years to come. An expert on federal public lands, Native American issues, and the West's arcane water laws, Wilkinson looks at the outmoded ideas that pervade land use and resource allocation. He argues that significant reform of Western law is needed to combat environmental decline and heal splintered communities. Interweaving legal history with examples of present-day consequences, both intended and unintended, Wilkinson traces the origins and development of Western laws and regulations. He relates stories of Westerners who face these issues on a day-to-day basis and discusses what can and should be done to bring government policies in line with the reality of twentieth-century American life. His examination seeks a middle ground between those who champion unrestricted growth and those who advocate complete preservation.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Critical Mineral Resources of the United States written by K. J. Schulz and published by Geological Survey. This book was released on 2017 with total page 868 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the importance and dependence of specific mineral commodities increase, so does concern about their supply. The United States is currently 100 percent reliant on foreign sources for 20 mineral commodities and imports the majority of its supply of more than 50 mineral commodities. Mineral commodities that have important uses and face potential supply disruption are critical to American economic and national security. However, a mineral commodity's importance and the nature of its supply chain can change with time; a mineral commodity that may not have been considered critical 25 years ago may be critical today, and one considered critical today may not be so in the future. The U.S. Geological Survey has produced this volume to describe a select group of mineral commodities currently critical to our economy and security. For each mineral commodity covered, the authors provide a comprehensive look at (1) the commodity's use; (2) the geology and global distribution of the mineral deposit types that account for the present and possible future supply of the commodity; (3) the current status of production, reserves, and resources in the United States and globally; and (4) environmental considerations related to the commodity's production from different types of mineral deposits. The volume describes U.S. critical mineral resources in a global context, for no country can be self-sufficient for all its mineral commodity needs, and the United States will always rely on global mineral commodity supply chains. This volume provides the scientific understanding of critical mineral resources required for informed decisionmaking by those responsible for ensuring that the United States has a secure and sustainable supply of mineral commodities.
