洪河 Hong He
淮河上游北岸较大支流,又名洪汝河。上游小洪河,源出河南省方城县东伏牛山脉祖师庙南麓,东南流经舞阳、西平、上蔡、平舆,至新蔡县班台与右岸支流汝河相会,下流至淮滨县麻里店附近入淮。班台以下称洪河或大洪河,其左岸有洪河分洪道,流经安徽省阜南县,于王家坝以下入□河分洪道。洪河全长312公里,流域面积1.238 万平方公里;其中位于京广铁路以西的山区、丘陵区约各占20%,以东的平原区约占60%。上游地区为淮河流域的暴雨中心之一,板桥水库附近的林庄雨量站1975年8月实侧3天(5~7日)总雨量为1605.3毫米;最大6小时、24小时雨量各为830.1与1060.3毫米,其中最大6小时雨量创世界大陆暴雨纪录。 过去因山丘区洪水无控制工程,中下游河道狭小弯曲(素有“九里十八湾”之称),堤防残缺,洪涝灾害严重。1949年后在上中游建石漫滩、板桥、薄山、宿鸭湖等大中小型水库143座,老王坡、蛟停湖2个洼地滞洪区,减轻洪水威胁。小洪河西平往下至黄泥桥段建有渠化通航水利枢纽。该段及洪河新蔡以下可常年通航,其余河段及汝河汝南以下可季节通航。
