“…According to them, the bridge scour process is controlled by W* and D * , while scale effects in D/d 50 distorted models are negligible. Bombar [79] found that the effect of flow deceleration during the falling limb of the hydrograph was weaker than the effect of flow acceleration during the rising phase on scouring. Schendel et al [80] investigated the role and impact of hydrograph shape, using W*, on tidal current-induced scour in physical models.…”

Foundation scour is among the main causes of bridge collapse worldwide, resulting in significant direct and indirect losses. A vast amount of research has been carried out during the last decades on the physics and modelling of this phenomenon. The purpose of this paper is, therefore, to provide an up-to-date, comprehensive, and holistic literature review of the problem of scour at bridge foundations, with a focus on the following topics: (i) sediment particle motion; (ii) physical modelling and controlling dimensionless scour parameters; (iii) scour estimates encompassing empirical models, numerical frameworks, data-driven methods, and non-deterministic approaches; (iv) bridge scour monitoring including successful examples of case studies; (v) current approach for assessment and design of bridges against scour; and, (vi) research needs and future avenues.
