澧河发源于河南省方城县四里店,由于河道上宽下窄,行洪能力自上而下递减,加之上游是河南三大暴雨区之一,洪水频发,出现超标准洪水次数多。据统计,自何口水文站建站以来,共出现超标准洪水22次,平均每5年2次,该河因而成为全省防汛重要河流之一。该河自建国以来已有3年(1975、2000、2004年)出现大范围漫溢决口,造成险工多,防汛任务繁重。何口水文站是澧河控制站,控制流域面积2124 km2,占澧河
Due to the narrow width of the channel, the capacity of flood discharge decreases from top to bottom. In addition, the upstream is one of the three heavy rainfall areas in Henan Province. Due to the frequent floods, there are many floods exceeding the standard. According to statistics, since the establishment of the mouth station, a total of 22 flood surges occurred in an average of two times every five years. Therefore, the river has become one of the important flood control floodwaters in the province. Since the founding of the river, the river has had a large-scale overflowing burst in three years (1975, 2000 and 2004), causing many dangerous workers and heavy flood control tasks. Hekou hydrological station is Bahe control station, control basin area of 2124 km2, accounting for Bahe
