摘要
This paper presents a high-resolution (2′X2′) numerical model of coastalcoupled wave-current interaction with explicit consideration of the effects of wave-currentinteraction on bottom stress. For two selected storms with measured data in the Yellow River coastalarea of the Bohai Sea, it is shown that the bottom stress calculated by using a coupledwave-current model is increased, as one would expect, compared with the bottom stress computed withan uncoupled current model. Moreover, the current velocity field is also changed, but thecorresponding current directions show less influence in the two simulations. The extents of changesin bottom stress and current velocity vary with storm intensities. The results further imply thatthe coupled wave-current model should be used as the basis for simulating the current velocity andsea level in the near shore region.
