湿润地区小流域产汇流计算及稳定性分析——以粤北山区为例

Runoff yield and confluence calculation and stability analysis for small watershed in humid area

对广东北部湿润地区小流域星丰(三)水文站和赤溪(三)水文站设站以来的暴雨、蒸发、洪水过程等水文资料进行产汇流计算,分析降径关系、入渗率f_c、汇流参数m等相关参数的稳定性,探讨湿润地区小流域产汇流分析的方法。

Xingfeng Ⅲ hydrological station and Cixi Ⅲ hydrological station are both located in the humid area of Northern Guangdong. Runoff yield and confluence calculation of small watershed was conducted based on the hydro- logical records of these two stations, including storm rainfall, evaporation and flood process etc. Analysis was made on the stability of relevant parameters such as relationship between precipitation and runoff, infiltration rate, confluence parameters, based on which the author discussed the method of runoff and confluence analysis for small water- shed in humid area.
