Introduction of inclined open channels for the control of surface runoff of slopes in road structures

The phenomenon of water erosion induced by runoff speeds at the surface of the embankments causes their instability. Particularly in road environments, gullying on the slope's surface due to runoffs causes landslides, which in turn cause considerable damage and consequent disorders to the road network. The aim of this research is to put in place a new technology for superficial water drainage on slope surfaces. Our study has developed a methodology involving the change of the geometric configuration of the water flow, aiming at velocity control of the flows by choosing slanting waterways with small slopes coupled to vertical drains. A modelling of the proposed solution will evaluate its effectiveness as to prevent the erosive factor and to identify other factors that are responsible for slope disorders.
