Abstract: Based on timeseries of the Landsat images from 1987 to 2017, the information of water-level fluctuation zone and inundation frequency in middle and lower reaches of the Hanjiang River was extracted, and the spatial and temporal changes and phase characteristics of the water-level fluctuation zone and water area were analyzed. The results show that in the past 30 years, the average area of fluctuation zone ranges from 76 to 256 km2, and water areas ranges from 183 to 550 km2, but it differs among different regions. In general, the fluctuation zone is characterized by a wide upstream and a narrow downstream. The area with the largest area of the water-level fluctuation zone is located in the Yicheng-Zhongshankou section of the middle reaches, and the smallest area is located in the Xiantao-Hanchuan section of the lower reaches. The overall inundation frequency of middle and lower reaches of Hanjiang River decreased in 1987-2001 and increased in 2002-2017, indicating the change of the temporal rhythm of the water-level fluctuation zone. The characteristics of the water area, fluctuation zone and the inundation frequency differ between in the large reservoir regions and in others. The water area and the inundation frequency of the reservoir regions increase greatly after the completion of the reservoir, and the fluctuation zone range decreases. But in other regions, the water and fluctuation area change little, and the inundation frequency increases first and then decreases.
