Adaptation and Application of a Surface Erosion Model for New Mexico Forest Roadways

摘要

The study was conducted to compare effectiveness of measures and associated costs. Data collected from forest roadways on four national forests in New Mexico were used to derive parameters for an existing computer based erosion and sediment yield model. The model was used to estimate sediment yields for different control measures. Yields were compared with costs of measures which were provided through a survey of forest engineers in Arizona and New Mexico. Results show the different costs of using various methods for reducing a unit of sediment yield from forest roadways, and can be used to help determine a best management method.
