测洪方案是水文测站测报洪水的重要技术依据,反映了水文测验断面水沙特性、测验河段水力特性、水文特征及测站测洪能力、测报设施设备、测洪方案等综合信息。采用不同的测验方式和方法所得的测验精度,都应该符合水文测验规范的要求。文章以息县水文站为例,探讨大洪水测洪方案的编制方法,以此借鉴,进而指导和规范洪水期水文测站的水文测验工作。
The flood measurement scheme is an important technical basis for hydrological stations to measure and report floods. It reflects comprehensive information of water and sediment characteristics of hydrological test sections, hydraulic characteristics of test sections, hydrological characteristics, flood measurement capability of stations, measurement and reporting facilities and equipment, and flood survey schemes. The test accuracy obtained using different test methods and methods should meet the requirements of hydrographic test specifications. This article takes Xixian Hydrological Station as an example to discuss the compilation method of flood measurement flood plans, and then draws lessons from it, and then directs and regulates hydrological test of hydrological stations in flood period.
