Experimental study on preventing flood of 1/100 frequency in huaihe river

摘要

After having completed river regulation work in recent years, the dike dis- tance up the reach of Lutaizi has been extended to 1.5-2.0 km in the Huaihe river. When the middle flood happened, such as those in 1956, 1982 and 1991, flood can pass through safely. If the flood of 1/100 frequency happens, the flood discharge at Lutaizi will be larger than safe flood discharge 10000 m~3/s in downstream Lutaizi.
