Abstract

Abstract

A hyperbolic mild-slope equation wave propagation model was united with a depth-averaged 2D tidal flow model and the wave effect on flow is generated by radiation stresses of waves added to the tidal flow model. The wave induced current in the Modaomen estuary in the dry season was investigated for the first time by the model with the topography measured in 2011. The numerical results show that during the ebb tide the seaward currents are reduced by the opposing wave and two stagnant zones arise inside the shoaling water of the mouth bar, the seaward currents in east and west shoals also decrease, but the seaward currents inside the east and west deep grooves increase. During the flood tide the landward currents are increased by the following wave and a washover zone arise inside the mouth bar, the landward currents in east and west shoals also increase, but the landward currents inside the east and west deep grooves reduce at the same time.
- Modaomen estuary,
- wave induced current,
- radiation stress,
- mild-slope equation,
- depth-averaged 2D tidal flow model
