Abstract : Active secondary and tertiary roads are a significant source of non-point source sediment from disturbed military lands. Roadway surface degradation, roadside gully development, deposition of sediments in culverts and ditches, and roadway flooding due to reduced ditch capacity are common problems encountered by the military land manager. The form of roadway degradation may vary, but the cause most frequently can be attributed to the intensity of use; improper road location, design, or drainage; or inadequate maintenance. The ability to identify the geomorphic condition of a road section and its adjacent slopes, as well as to predict potentially unstable conditions, can significantly enhance the timeliness, placement, and effectiveness of maintenance or mitigation measures. This report is intended to provide land managers and road maintenance personnel with supplementary information to promote a better understanding of the geomorphic condition of the roadway, thereby enhancing the ability to prevent and mitigate degradation. Use of this information should simplify selection, placement, and timing of the most appropriate maintenance measures typically applied to the secondary road or tertiary trail.
