设计暴雨是为防洪除涝工程规划与设计拟定、控制时段雨量符合指定设计标准、时空分布符合当地降雨特性的暴雨过程，其关键技术参数包括致灾雨型、不同历时的设计雨量、时空分配组成等。\n
设计洪水位是指水利工程设计时，在一定设防标准条件下考虑保证工程防洪安全要求所设计的水位。在长江下游典型水系太湖流域这样的平原河网地区，设计洪水位是确定河道堤防堤顶高程，以及沿线的闸泵工程门顶高程等工程设计关键技术参数的最主要依据之一。", "ds_source": "

Design storm is for flood control and flood control project planning and design, control time rainfall in line with the specified design standards, spatial and temporal distribution in line with the local rainfall characteristics of the rainstorm process, the key technical parameters include the type of rainfall, the design of rainfall at different times, spatial and temporal distribution of the composition of the flood control project planning and design.\n
Design flood level refers to the design of water conservancy projects, in a certain set of defense standard conditions to ensure that the project flood safety requirements designed by the water level. In the lower reaches of the Yangtze River in the typical water system of the Taihu Lake basin such as the plains of the river network area, the design flood level is to determine the top of the river embankment elevation, as well as along the top of the gate of the gate and pump project elevation and other key technical parameters of the engineering design of the one of the most important basis.
