在去冬今春的水利高潮中,全国各地修建了大批中小水利工程。今冬明春,将掀起规模更大的水利建设高潮,将有成千成万个中小水利工程需要兴建。但在规划设计工作中,却遇到中小河流水文资料缺乏,算水赈缺少依据的困难。为了满足中小河流水文计算的需要,水利科学研究院水文研究所,与各流域、各省水利机关合作编制了“中国雨量、径流图表”、“中国暴雨参数图集”及“小汇水面积雨洪最大径流计算 In the winter of last spring and the climax of water throughout the country built a large number of small and medium-sized water conservancy projects. This winter and next spring, will set off a climax of the larger water conservancy construction, there will be tens of thousands of small and medium-sized water conservancy projects need to be built. However, in the planning and design work, it encounters the shortage of hydrological data in small and medium-sized rivers and rivers, and it is difficult to count on the lack of water relief. In order to meet the hydrological calculation needs of middle and small rivers, the Institute of Hydrology of the Institute of Hydraulic Research has compiled “China’s Rainfall and Runoff Charts”, “China’s Atlas of Rainstorm Parameters” and “Small catchment rainstorm” in cooperation with various river basins and provincial water conservancy agencies Maximum runoff calculation
