Abstract

In order to perform conservative scour analyses for coastal bridge sites it is necessary to develop realistic hydraulic simulations which provide worst case estimates of depth and velocity. Within the coastal floodplain it is likely that these worst case hydraulic conditions do not arise from extreme events (i.e. Q-100), but rather events whose return period is significantly smaller. For these conditions time-dependent simulations can be used to identify the required scour parameters. The benefits of using a time-dependent simulation are demonstrated through the comparison of steady and unsteady model results.
