主　　题：beach morphodynamic type dimensionless fall velocity relative tidal range wave power level straight beaches 

摘      要：Currently beach morphodynamic classification is the most important foundation to conduct associated coastal geomorphological *** paper carried out beach morphodynamic classifications for 12 straight beaches on headland-bay coasts based on field survey and evaluated the applicability of the most widely used dimensional fall velocity parameter(Ω)and relative tidal range parameter(RTR).One reflective,five intermediate and six non-barred dissipative beaches were visually classified and sand size seemed to be a key factor to differentiate these *** studied beaches were in relatively low wave energy environments(Hs3 KWm-1 and MSR2 *** was found that the model of the traditional winter-and-summer profiles was not applicable in the study area in despite of distinct wave *** studied beaches were more possible to hover around a limited range due to relatively low background wave environments and variability without considering typhoon impacts,which needs further research on actual breaker wave conditions and beach morphodynamic type responses to typhoon events.
