The manuscript documents a 15-year research activity on live-bed scour at river bridge piers. It first reviews a prototype study for a laboratory-scale model that was used to design a scour countermeasure on the major Italian river. The prototype study stimulated a reconsideration of the process mechanism, that has been then studied in an idealized facility. The latter has been configured in order to emphasize several key phenomenological aspects. In this paper, focus is given onto model design, instrumentation and experimental procedures, consistently with the main scope of the conference. Based on the latest results obtained, some prospects are provided to orient future research.

Abstract

The manuscript documents a 15-year research activity on live-bed scour at river bridge piers. It first reviews a prototype study for a laboratory-scale model that was used to design a scour countermeasure on the major Italian river. The prototype study stimulated a reconsideration of the process mechanism, that has been then studied in an idealized facility. The latter has been configured in order to emphasize several key phenomenological aspects. In this paper, focus is given onto model design, instrumentation and experimental procedures, consistently with the main scope of the conference. Based on the latest results obtained, some prospects are provided to orient future research.
