驮娘江八达水文站气象水文耦合的洪水预测探讨

Meteorological and hydrological coupling flood prediction at Bada Hydrological Station of Tuoniangjiang River

八达水文站是驮娘江上游第一个控制水文站,也是驮娘江龙头水电站威后水电站主要入库控制站,同时位于西林县城,也是西林县城的防洪水文站,但控制流域面积小,汇流时间短。探讨了该水文站洪水预报模型建立、应用条件和基于气象降雨数值预报的模型应用,以延长洪水预报预见期。

Bada Hydrological Station is located in Xilin County. As the first control hydrological station on the upper reach of Tuoniangjiang River, this station is also the control station for both Longtou Hydropower Station and Weihou Hydropower Station, and the flood protection station of Xilin County. This station is characterized by small control river basin area and short concentration time. The author probed into the setting up and applicable condi- tions of flood prediction model at this station and the model application based on meteorological precipitation forecasting data, so as to prolong the flood forecasting period.
