Hillslope erosion and weathering rates in Earth's most rapidly uplifting mountains
Knowledge of hillslope erosion rates and processes is necessary for understanding landscape response to tectonic and climatic forcing and for determining the degree to which mountains regulate biogeochemical cycles and global climate. Landslide erosion and soil production are the principle …

Post-fire Response of Little Creek Watershed: Evaluation of Change in Sediment Production and Suspended Sediment Transport
… were found to decrease, while an increase in hillslope sediment production was documented. High intensity, short duration rainfall (up to 87 mm/hr for 10 minute duration) initiated extensive rilling and minor channel-derived debris torrents originating from the upper south facing slopes. …

A reassessment of the genesis of the Sangamon stone line and texture contrast profile in McDonough County, western Illinois
… interpreted as former surface lags fanned by hillslope erosion owed to changes in environment, mainly climate. According to erosion models, texture contrast soils with stone lines are developed in two parent materials where the stone line separates an underlying, truncated, often fine-textured …

Development of a research and demonstration facility for the evaluation of stormwater runoff, erosion control, and sediment control best management practices
… rates and volumes of stormwater runoff and soil erosion. Soil erosion is a major global environmental problem and the fourth leading cause of water quality impairment in U.S. Although many commercial products are available for erosion and sediment control, there is currently a deficit in …

Holocene sedimentary history of Chilliwack Valley, Northern Cascade Mountains
… to higher order tributary basins. Rates of hillslope erosion are estimated using a diffusion-based relation for open slopes and delimitating the volume evacuated from major gully sources. Digital terrain models of paleo-surfaces are constructed to calculate total sediment erosion and …

Modeling Soil Erosion in the Upper Green River, KY
Off-site soil erosion has tremendous impacts on the present state of most river systems throughout the United States, contributing sediments to channels mainly as nonpoint pollution resulting from land-use and agricultural practices and leading to sedimentation downstream and downwind, a decrease …

Biogeomorphology and soil geomorphology of small semiarid basins, northeastern Arizona : influences of topoclimate and climate variations
… climate changes affect processes of weathering, erosion and plant community establishment on hillslopes in this semiarid environment. In small basins formed at the base of Black Mesa escarpment west of Chinle, Arizona, Jurassic sandstones cemented mainly by clay minerals weather by hydration, …

Buried Surface Horizons in Saskatchewan Croplands Provide Insight into Microbial Soil Carbon Cycling and Development of Persistent Organic Matter
The accumulation of soil from hillslope erosion in depositional landscape positions can bury the original A horizon soil, leading to a disconnect of C-rich surface soils from surface environments due to burial. The buried C then serves as the primary C for the buried native microbial community. The …

Assessing the dynamics of soil erosion and sediment transport under increasing land use pressures in East African Rift Catchments
… dynamics in land use and land cover change, soil erosion and sediment transport in East African Rift Catchments. This contribution forms a blueprint for future studies using sediment tracing, radionuclide dating, Bayesian Mixing Models and soil erosion mapping, and their reciprocal integration in …
