The flood crest travel to the outlet of a watershed is related with some characteristics of the watershed. This paper calculated the flood crest travel duration in the Yangtze River Basin based on the gravitation driven principle and hypsometric curve. The results show that the flood crest travel durations of the 53 sub-basins in the Yangtze River Basin obtained by ArcGIS have obvious relationship with the characteristics of the sub -basins，there is a linear relation between the value calculated with the method based on hypsometric curve and the value calculated with the empirical formula. The research could be used for studying the relationship of the hydrological response with watershed geomorphology and real-time flood forecast.
