The objective of this paper is to analyze the characteristics of the nearshore bars using the long-term measured data of cross-shore sediment transport for Duck beach, North Calolina, USA. The effect of outer bars are directly included in the analysis to understand the characteristics of the sequential nearshore bars. Many parameters related to the nearshore bars are presented by the simple relationship. It is found that the nearshore inner bars generally move offshore as time goes. After the outer bars are formed at some position, however, the inner bars start to move landward with time and outer bars become inner bar again. Also it is shown that the seasonal characteristics of inner bars are distinctly different according as the outer bar exists or not.
