从1991年江淮大水中吸取有益的经验,切实搞好海河流域的防汛、减灾,是我流域水利工作中的一件大事。如果海河流域发生较大洪水,目前水利科技界比较能够取得共识的、带有规律性的看法,大体上包括这样几个方面:从雨情看,海河流域的特点明显,极易发生集中降雨,高强度暴雨将迅速形成强大径流;从洪水流势看,暴雨径流经山丘区向下游扩展迅速,很快可能形成由线到面的洪水漫流;从河流泄洪能力看,由于河道淤积,多年未经
It is an important event in the water conservancy work in our basin to draw useful experience from the large floods in JAC in 1991 and do a good job in flood control and disaster reduction in the Haihe River Basin. If there is a big flood in the Haihe River Basin, the water conservancy science and technology community can now reach a consensus and take a regular view, which basically includes the following aspects: From the view of the rainstorm, the Haihe River Basin is characterized by obvious rainfall, high rainfall, high Heavy rainfall will quickly form a strong runoff; from the flood trend, the storm runoff spreads rapidly to the lower reaches through the hill area, and may soon lead to a flood-to-surface flood. According to the flood discharge capacity of the river, due to siltation of the river,
