  [ Topography]   The terrain of Ezhou is high in the southeast, low in the northwest, and flat in the middle; with 485.8 meters elevation, "Sifeng Mountain” marks the highest point of the city, and "Liangzi Lake”, the lowest point, registered an elevation of 11.7 meters. There are four types of geomorphological forms: the Yangtze River alluvial terraces in the north (Baihu Town - Linjiang) and the east (Yanji - Yangye); hills in the east and the east side of the south (Baizhi Mountain, Fengjianzi Mountain and Zaoshan Mountain); hill-shaped plains in the north and the west side of the south, with about 90 meters  elevation; stagnant water lacustrine plains in the middle (Liangzi Lake, Ya'er Lake, Sanshan Lake, and Yanglan Lake, traversing the central region of Ezhou). 

  [ Hydrology ] Running from Baihu Mountain in Wuhan, the Yangtze River passes through Ezhou City.
