1991年洪涝灾害后,国家对淮河流域进行了重点投资治理,相继完成了许多大型骨干工程,一些主要行洪河道的防洪标准得到较大提高,抵御流域大洪水的能力大大增强。但流域地方内河的防洪标准不足、行洪不畅、险工较多和阻水障碍严重等现象仍比较突出,对安全度汛十分不利。汛期局部暴雨,出现河道洪水决口漫溢、造成区域洪灾的可能性极大。从历年各地发生的局部洪灾来看,多数是由于暴雨集中、排水不畅、内河出现决口造成的。鉴于上述状况,各地在准备防大汛、抗大洪的同时,应对地方内河的防汛工作引起足够的重视。
After the floods in 1991, the state conducted key investment and treatment of the Huaihe River Basin and completed many large-scale backbone projects in succession. Some major flood control flood control standards have been greatly improved, and the capability of resisting floods greatly enhanced. However, inadequate flood control standards for inland waterways in river basins, poor flood control, more dangerous workers and serious water blockage are still quite prominent, which are very unfavorable to flood safety. During the flood season, local heavy rains and flooding in the river courses have spilled over, resulting in a great possibility of flooding in the area. In view of the local floods that have taken place in various places over the years, the majority are caused by the concentration of heavy rainstorms, poor drainage and the emergence of rivulets in the river. In view of the above situation, while preparing for flood control and flood fighting in various places, flood control work in the inland river should be given sufficient attention.
