Aim of the pilot project
Several road and railway stretches in Norway are exposed to debris flows and flash floods that are initiated by very local precipitation systems with a relatively short duration like less than one hour to a few hours. The focus landslide prone area will be county road 63 at Trollstigen, which is highly prioritized by Norwegian authorities due to the very high exposure, particularly due to the high traffic density during the summer months. The slopes around the road are steep and the catchment areas are small and sparsely vegetated, causing quick runoff during intense rainfall. The aim is to implement a cost-effective early warning system that integrates both regional and locally monitored data.
Innovation potential
The innovation potential lies primarily in developing the framework for an early-warning system that efficiently integrates regional and local data and that can be straightforwardly adapted to other sites with similar conditions. In the long term, the system could be automatically connected to regional or national warning services. The added value of this activity to the end-user (e.g. the NPRA (Statens vegvesen), counties or other owners of infrastructure) are early-warning systems for flood and debris flows that enable the optimal management of risk by closing infrastructure for the shortest period necessary, allowing normal use again as soon as the acute risk has passed.
