Soil quality and soil erosion
"Soil Quality and Soil Erosion is based on invited and contributory papers of a July 1996 symposium organized by the NC-174 and NC-59 Committees in conjunction with the 51st Annual Meeting of the Soil and Water Conservation Society at the Keystone Center in Colorado. The authors…
Soil erosion has become a problem of crisis proportions in developing countries around the globe, and better approaches to land management are desperately needed. This book provides analytical frameworks to guide the creation and appraisal of soil erosion control programs. The a…
•Addresses soil erosion and dryland farming in Mainland China-approximately 40 percent of the book deals with China •Provides global examples of dryland farming •Examines dryland farming systems and soil water management, environmental quality and sustainability, erosion control…

"I've seen the Sudan, traveled in South and Central America and been all over Europe, but I've never seen what I've been able to see on this tour [of the Loess Plateau, China]."--Ed Skidmore, soil scientist, WindErosion Research Unit of the Agricultural Research Service, USDA, M…

Knowledge of denudation rates over geologic timescales provides important insight into the processes that govern soil formation, the regulation of Earth’s climate, and the evolution of landscapes. Accurately establishing long-term denudation rates is also key to understanding ho…
This project expands on the 4200-year history of Laguna Los Mangos by adding diatom analysis to existing records of pollen, charcoal, elemental composition, and stable light isotope analysis. Diatoms were counted in peroxide-treated samples, and data were analyzed using cluster …
Fire is a global phenomenon that annually burns approximately 3% of Earth’s terrestrial surface. While fire is an important component of many terrestrial ecosystems, climate change and anthropogenic influence are expected to alter global fire regimes (particularly fire frequency…
This work concerns the planimetric evolution of free meandering rivers, whose associated riverbank erosion and channel changes notoriously pose a hazard to infrastructure within their vicinity as well as affect the health of the river ecosystem. It aims to address two research n…
Planetary surfaces provide a window into the geologic past of planets and can offer clues into their history of deformation. For example, endogenic forces such as tectonic activity resulting from secular planetary cooling can produce fault-driven topography that can be investiga…
Sediment erosion has led to major societal challenges across the globe including scour around bridge piers, infrastructure collapse, and poor ecological function in streams and along the coast. While stream erosion mitigation is well studied, coastal erodibility requires more un…
Scour evaluation is a critical step for assessing the stability of several types of highway infrastructures during design and post construction stages as well as throughout the operational life of the structure. During the design stage, the knowledge of scour potential and depth…
Soil erosion is a complex, natural process that often is accelerated by such human activities as land clearance, agriculture, construction, and surface mining. Accurate soil erosion type/intensity maps can be effective tools in aid of soil erosion control efforts. The principal …
