Abstract:

As part of the Armys continuing effort to maintain and enhance the natural resources of military installations, environmental quality managers must assess the impact of training activities on soil erosion. Six watershed study areas were selected at Fort Carson, each having an existing sediment catchment basin. These watersheds were considered to be representative of the soil types, vegetation cover, topography, and land use in the Fort Carson region. Borings were made in the catchment basins to determine the accumulated sediment volume. These data were used with the age and area of the basin to estimate the average annual sediment yield for each watershed. A watershed erosion index reflecting the collective influence of rainfall, soil erodibility, topography, and land use was derived using the Universal Soil-Loss Equation as a basis for development.
