Watershed boundary adjustments have occurred throughout the Black Hills in response to post-Laramide fluvial incision within and peripheral to the Black Hills. Geologic field mapping and stream profile analyses have led to identification of two broad knickzones that separate three distinct fluvial geomorphic surfaces. The uppermost relict surface e...

Geomorphology is the study of landforms and landform evolution. The topic traditionally has been studied both qualitatively, which is the description of landforms, and quantitatively, which is process-based and describes forces acting on Earth’s surface to produce landforms and landform change. The shift to a more quantitative approach was largely...

Abstract Erosion of sediment and soil by wind arises when the kinetic energy in the passing airstream exceeds the energy employed in adhering the grain to the surface. Initial grain motion is achieved at this instant and the grain will be transported in saltation as a series of short hops along the surface. Each time the grain impacts the surface,...

Prediction of PM10 dust from a defined agricultural field during wind erosion events depends on factors which vary both spatially and temporally. Wind energy is the driving force for both wind erosion and dust suspension and may be calculated from wind speed above the threshold for erosion. Wind speed varies both seasonally and with topography. Bot...
