Based on these experiments, the scour process around bridge abutments has been assessed.
The scour process induced by plunging jets is an important topic for hydraulic engineers.
However, existing empirical equations do not always provide accurate scour prediction due to the complexity of the scour process.
Nevertheless, in rivers the scour process generally occurs in correspondence with a flood event, which is characterized by discharge varying with time.
To avoid the structural collapse of any hydraulic structure, the scour process is one of the primary factors that must be controlled.
Generally, the analysis of the scour process is conducted under steady flow conditions, assuming that the maximum discharge is occurring for sufficient time to reach the equilibrium scour configuration.

The SVR model not only estimates the time-dependent scour depth more accurately than conventional regression models, but also provides results that are consistent with the physics of the scouring process.
The scouring process is described via a time-history analysis in which the elements representing the soil are progressively removed from the model according to a specific scour evolution.
Although there were many studies in this regard, which mainly focus on the discharge capacity, the local scour and the mean flow field, some issues remain to be further investigated, for example, the variation of the mechanical energy during the scouring process, and the adjustment of the unsteady turbulent flow after the local scour with the downstream steady uniform flow.
