Abstract: The objective of this paper is to present results of a comprehensive hydrologic transport study, designed to assess potential surface water contamination, resulting from the release of Depleted Uranium (DU) contaminants into the environment. Study results indicate that theoretical potential exists for the downstream contamination of surrounding biological and water resources of the area. Transport calculations are based on Novak's concept of incipient motion, namely, the relationship between the size, shape, density of the DU particle as well as the depth and velocity of water for critical flow conditions. When the velocity in the channel exceeds the critical velocity, particle motion will occur.
