Abstract

Hydrological and sediment fluxes were monitored for a 1 yr period in a tropical headwater catchment in Peninsular Malaysia where a 3 yr old logging road caused substantial Hortonian overland flow (HOF) and intercepted subsurface flow (ISSF). Here the AA. elucidate processes related to the alteration of sediment and hydrological fluxes from road surfaces particularly due to ISSF in addition to conventionally studied HOF and HOF-driven erosion. ISSF caused not only additional road-generated sediment export, but also exacerbated HOF-driven erosion by creating a poor foundation for vegetation recovery on the road surface
