无实测资料地区中小河流治理工程洪水计算——以韶关市乌石水为例

Calculation of the riverside governance of river channels in the area of no real data——take Wushishui in Shaoguan as an example

部分地区由于河流控制面积小或测站建成较晚等原因,缺乏河道径流资料,不便于河道治理、生态建设工程的设计洪水分析。针对该问题,以韶关市乌石水中小河流治理工程为例,采用综合单位线法、推理公式法和地区经验公式法3种方法对设计洪水进行分析计算,同时结合工程实际情况,对比分析各方法的优缺点,建议该地区采用综合单位线法作为最终计算结果。相关研究可为类似无径流资料河流的洪水计算提供借鉴。

Due to the small control area of the river or the late completion of the measurement,the lack of river runoff data in some areas brings inconvenience to the implementation of subsequent river channel management and ecological construction projects.In response to this problem,studying the small and medium-sized river governance project of Wushishui in Shaoguan City as an example,the comprehensive unit line method,reasoning formula method and regional experience formula method were used to analyze and calculate the design floods.Compare the advantages and disadvantages of each method,and finally recommend that the region adopt the comprehensive unit line method as the final calculation result.Related calculations in the article can provide reference for rivers similar to data-like data.
