西江界首段的河相关系研究

Study on hydraulic geometry from Jieshou in Xijiang River

从航道工程的角度,概括总结了优良河段及河相关系的研究和应用现状,提出了在冲淤资料缺乏时优良河段的选择方法,并实际应用于西江界首河段,选取了西江界首段多个沿程横断面河相关系统计分析,成功建立了整治水位下的河相关系式,为航道整治提供参考。

Based on the research and application experiences about the fine reach and hydraulic geometry in waterway engineering, a method to select fine reaches was proposed if not enough erosion and siltation data areavailable. Being applied on the river reach fr^aa Jieshou in Xijiang River, lots of fine reaches were selectedand their hydraulic g^etry formulation under waterway regulation water level was successfully established. The research resultscan be used in waterway regulation planning.
