In the event of erosion flows, the road is one unique surface with various flow and deposition characteristics. Earlier studies focus on erosion features on shores and coasts and sometimes on desert plains as a result of wind erosion, but hardly on roads. Erosion features are detrimental to road designers, constructors, and users. This paper focused on gravel roads which constitute a larger percentage of the rural roads. These are a key to accumulation of wealth for developing countries. It also looked at the identification, formation, and extracting effects of features as a result of erosion on the road surface pertaining to various road surface characteristics. Rills and dunes on roads are active features which gully up bigger parts of the roads causing flooding and other dangerous effects. Various experiments like sieve analysis, runoff speeds and measuring road rill/dune sizes with respect to slope size, rain intensity, and road sizes were considered for this study. The main data analysis tool used was STATA V11. Findings included higher runoff speed on roads than other erosion fields, determination of the rate of road reduction, flooding by rills or dunes and provision of good background to modeling erosion on roads.
