特定洪水过程研究

Study on Specific Flood Hydrograph

提出特定洪水过程的新概念及其内涵,论述了工程防洪标准的形式意涵和实质意涵,引出特定洪水过程与防洪标准之间的联系——洪水过程形式频率新概念。阐述特定洪水过程的三种蜕变类型及其推求方法。指出当前推求特定洪水过程的同倍比和同频率法优缺点,最后简述了新推求方法的基本思路。

According to the study on flood hydrograph, the new concept of specific flood hydrograph and its connotation were pro- posed. Meanwhile, the external and essential implication of engineering flood prevention standard were expounded. And then the re- lationship that was the new concept of external frequency of flood hydrograph between specific flood hydrograph and flood preven- tion standard was drawn. The specific flood hydrograph of three types of transformation and its calculation method were elaborated. The advantages and disadvantages of the common multiple method and the common frequency method of specific flood hydrograph were pointed out. A brief introduction about the basic idea of new calculation method of specific flood hydrograph was given.
