| Abstract: | In lhis paper, a numerical model for predicting the unsteady nearshore circulationdue to wave-current interaction was proposed. In addition io the traditional continuity,momentunm and energy. equations, the dispersion and refraction relations were includedin the governing equalions. Moreover, the effects of lateral shears, wind, radiation andbottom stresses were analysed in the governing equalions. Therefore, we expect thatthis model may more completely and exactly reflect the law of ware-currentinteraction. In part (II) we will adopt the selective lumping two-step explicit finite elementmethod to solve the model, and some examples will be presented. |
