Abstract
Unsealed roads and tracks are a major source of sediment in managed forestry environments. Traditionally, on-site erosion mitigation measures for such surfaces have been designed to limit erosion of the road/track surface or travelway. Recent emphasis on controlling off-site impacts has added two more design principles to the management of runoff from roads and tracks. These include the prevention of gully development at the outfall slope and minimizing the sediment load reaching the stream network via overland flow pathways. In this paper we provide a combined framework for road and track drainage design which satisfies these three design principles. The framework predicts the maximum spacing of road drainage structures as a function of road surface gradient, gradient of the outfall hillslope and the proximity of the outfall to streams. This integrated approach is designed to produce practical and simple guidelines to effectively manage road and track surfaces in forested and other environments..
