Many efforts have been made to develop coupled current-
wave models (Xie et al., 2001; Moon, 2005; S.rensen
et al., 2006;Warner et al., 2008; Liang et al., 2007;
Liu and Xie, 2009; Tang et al., 2009). Most of these
models are three-dimensional, structured grid models
while unstructured grid models are usually two-dimen
