Hydrologic modeling of range-land erosion processes has made significant advances in the past five years with the development of the Water Erosion Prediction Project (WEPP) model.

The Rangeland Hydrology and Erosion Model (RHEM) was designed to fill that need. Wind erosion is a major contributing factor to rangeland soil degradation. The process is highly sensitive to variability in soils, weather, and climate, which influence wind erosivity, protective vegetation cover levels, and soil susceptibility to entrainment and transport downwind (see Box 1 for definitions of terms).
Wind erosion is also highly sensitive to patterns of land use and land Cited by: major impacts on runoff and soil erosion processes on rangeland ecosystems. These processes and activities affect ecosystem function over a wide range of spatial and temporal scales (Williams et al., b).

When the soil solution freezes, some portion of the total water content remains as liquid water. This is critical because the amount of ice formed largely determines the impact of soil freezing on the soil properties that affect.

Wind and Water Erosion. Erosion research on rangelands has traditionally focused on water erosion and associated fluvial processes. One key advance in recent decades is recognition of the importance of wind-driven transport (aeolian) and its linkage with water erosion (Breshears et al.

For water erosion, there is a need for models that can represent splash and thin-sheet ﬂow processes that dominate sediment trans-port at the plot and hillslope scales in some rangelands (Nearing et al.

Abstract. The ability to assess the impact of management actions on soil and water resources is crucial to sustainable land management. The Rangeland Hydrology and Erosion Model (RHEM) was developed as an assessment and decision support tool for resource management agencies and has been used to estimate soil erosion at national, regional, and local scales for both disturbed and undisturbed.
About this book This new edition is a major revision of the popular introductory reference on hydrology and watershed management principles, methods, and applications. The book's content and scope have been improved and condensed, with updated chapters on the management of forest, woodland, rangeland, agricultural urban, and mixed land use.

Rangeland-specific erosion models can serve as a powerful decision making support tool and help land managers identify areas of concern and predict changes in ecohydrological processes occurring on rangelands.

Accelerated soil erosion occurs when anthropogenic processes modify soil, vegetation, or climatic conditions causing erosion rates at a location to exceed their natural variability.
Identifying where and when accelerated erosion occurs is a critical first step toward its effective by:. Rangeland measurements may also involve assessing the foraging and browsing activities of various animal species, which may also involve making a census of wildlife populations.
At the broader, landscape scale, rangeland measurements can involve assessing the level of recreational use or of erosion occurring within a watershed.
Soil water repellency is common on unburned and burned conditions for many rangeland ecosystems. Repellency can strongly influence infiltration, runoff, and vegetation recovery from fire. Repellency is highly variable in space and time and causes of temporal variability remain poorly understood.
