我国大部分暴雨洪水地区,对水库安全造成威胁的大多是长历时大暴雨所形成的洪水。因此在水库设计洪水计算中应当以长历时设计暴雨做为考虑的对象。目前大部分中小水库常用推理公式或经验公式确定最大流量,在使用这类方法时,设计洪水过程线多采用概化过程 Most of the rainstorm areas in our country are mostly floods caused by prolonged heavy rainfall as a threat to the safety of reservoirs. Therefore, in the calculation of reservoir design floods, torrential rain should be designed for a long time to be considered. At present, most small and medium-sized reservoirs commonly used inference formula or empirical formula to determine the maximum flow rate, in the use of such methods, design flood process line to use more generalization process
