【摘要】 广东省综合单位线法和广东省推理公式法是广东省设计洪水主要计算方法，该文利用粤北地区韶关市境内中小河流水文站实测水文监测数据对综合单位线滞时m₁和推理公式汇流参数m进行复核，并将复核成果与查算值对比分析，探索变化环境下设计洪水计算方法的参数变化规律，为设计洪水计算提供修正依据。更多还原

【Abstract】 The Guangdong synthesis unit hydrograph method and reasoning formula method are the main calculation of design flood in Guangdong Province. This paper uses the measured hydrological monitoring data of small and medium-sized river hydrological stations in Shaoguan City, northern Guangdong Province, to recheck the integrated unit hydrograph hysteresis m₁ and the convergence parameter m of the inference formula, and compares and analyzes the recheck results with the checked values, to explore the parameter variation law of the design flood calculation method under the changing environment, and to provide a correction basis for the design flood calculation.更多还原
