An important natural hazard affecting to the road networks and to the traffic in semiarid areas is caused by the flood waters in road stream crossings. The paper has as principal aim to propose a methodology for evaluating the hazard of road-ephemeral channel crossings, from exposition levels and hydrological, hydraulic and morphological criteria. This approach has been applied to the coastal southern area of the Murcia Region, obtaining 54 maps of hazard indicators for road-ephemeral channel crossings under different hydrological conditions.
