雅碧江唐古栋垮山堵江形成巨大库容后溃决，下游的三个水文站中洼里站被冲毁，沪宁和小得石水文站取得了宝贵的实测资料。本文对雅砻江３００公里直到金沙江河口进行了洪水演算，经多次迭代得出的上游洪水过程线与成都勘测设计研究院洪痕复核资料相符，并纠正了水文年鉴上的错误数据，按新得出的上游洪水过程线作为上游边界进行计算，得出的沪宁和小得石站的计算值与实测值一致。本文的有关数据对雅砻江梯级开发和准备兴建的几个大型电站有重要参考价值。
After the collapse of the ancient terrain of the Yibi River, a large reservoir was formed and the reservoir was destroyed. The downstream stations of the three hydrological stations were washed away and the valuable measured data were obtained from the Shanghai-Nanjing and Xiaodeshi Hydrological Station. In this paper, the flood calculation is carried out from 300 km to Yingsha River to the Jinsha River estuary. The upstream flood process line obtained through multiple iterations is consistent with the flood inspection data from Chengdu Survey and Design Institute, and the error data on the hydrographic yearbook are corrected. The newly derived upstream flood process line is calculated as the upper boundary and the calculated values of the Shanghai-Nanjing and Xiaodeshi stations are consistent with the measured values. The relevant data in this paper have important reference value for the development of the Yalong River and several large power stations to be built.
