Abstract:Poyang Lake is the largest freshwater lake with seasonal throughput in China.In this paper,the following data of the Poyang Lake were collected and analyzed,the water level data of hydrological stations,the wind field observation data of the meteorological station and the bathymetry measured in the lake area.Then,the wave height distribution in Poyang Lake was calculated and analyzed with nu-merical simulation methods based on wave action conservation equation.The calculation results of nu-merical methods and standard methods were compared.The results of the comparison showed that the calculation results of the two methods are generally close to each other,and the calculation results of the numerical method are slightly larger than that calculated with the standard method.Finally,we concluded that the significant wave height(H13%)around Poyang Lake under extreme high water level conditions varied between 1.70m and 2.08 m and the mean wave period(Tm)varied between 4.39s and 5.25s.
