三磊坝水文站位于四川省广元县境内,是白龙江流域的控制测站,流域面积28896km~2.由于该测站地处川北暴雨区,每年汛期洪水发生的次数频繁,峰型尖瘦,给测流工作带来一定的困难.例如1961年的洪水,为当时设立测站以来的最大洪水,冲毁了测站的一些设施,迫使测流工作不能正常进行,致使实测资料精度下降.三磊坝水文站是宝珠寺、紫兰坝水电站水文计算的依根站,也是研究白龙江下游地区洪水组成的依据站,实测资料成果精度的高低,将直接影响到工程的经济与安全.1965年
Sanlei dam hydrological station is located in Guangyuan County, Sichuan Province, is the Bailongjiang River Basin control station, the basin area of 28896km ~ 2. Because the station is located in northern Sichuan rainstorm area, annual floods occur frequently, the peak sharp thin to For example, the flood in 1961, which was the largest flood since the establishment of the station, destroyed some of the facilities at the station and forced the normalization of flow measurement, resulting in a decrease in the accuracy of the measured data. Dam hydrological station is Baozhusi, hydropower station hydropower hydropower hydropower station according to the root, but also to study the composition of the lower reaches of Bailongjiang flood station, the measured data accuracy, will directly affect the economy and safety of the project.
