河北沿海小青龙河流域产汇流参数分析

Analysis on the Runoff Generation and Concentration Parameter in the Basin of Xiaoqinglong River in Hebei Coast Area

流域产汇流参数的确定是洪水预报和工程规划设计的重要依据。阐述了各产汇流参数在不同条件下的计算方法，结合小青龙河司各庄水文站实测资料，分析计算了流域最大损失量Im、前期影响雨量Pn、稳定下渗率fc、汇流参数m值，对掌握小青龙河流域产汇流规律及洪水预报有一定参考价值。

Determination the runoff generation and concentration parameters in watershed is an important basis for flood forecasting and proiect planning and design. It expands parameters of the runoff method in different conditions,with measured data of the Sigezhuang hydrometric sta tion in Xiaoqinglonghe, analysis and calculates the maximum loss of watershed-Im, antecedent rainfall Pa, steady infiltration rate-f c, and concen- tration parameter m. It has some reference value for predominating the regular pattern of watershed runoff and convergence and flood forecasting in the basin of Xiaoqinglong river.
