| 5. | Based on the analysis of flood data of 1935 , 1937 , 1954 , 1958 and 1982 , the flood storage effect is related to flood volume , flood process , intensity of dyke break and others
在现状堤防条件下，如果再发生1954 、 1958年量级的洪水，在确保洛河北大堤安全的情况下，有计划地使用夹滩及南岸滞洪区滞洪，则夹滩地区对入黄洪水的削峰率可达20 % 25 % 。 |
| 6. | From the case study , it can be seen that the results of two algorithms can satisfy the restrictions of the actual peak flood discharge and flood volume and keep the mode of the typical flood effectively and avoid the manual randomicity
通过实例计算可以看出，这两种算法计算结果均能较好的满足洪峰洪量约束要求，并有效保持了典型洪水的模式，避免了人工修匀的任意性。 |
