摘要
Abstract
A StreamPro ADCP is used to carry out measurements in the Shengtian canal section of Beijing's Juma river.A cross-section with relatively straight water flow from up to down stream and of a regular geometric shape are selected,and a non-conventional flow measurement method is used.By dividing the cross-section up into several vertical lines,and using fixed vertical line method,the correct velooities at different depths along each vertical line are measured,thereby the velocity distribution signature of a typical river cross-section is obtained.On the basis of the result,using velocity area methods as the one-point mid-stream,one-point,vertical-line,and three-point methods,the respective typicality in calculating regulated open channel water flows are studied.The purpose is to collect velocity distribution data from different conditions,forming a database of typical open-channel velocity distributions for hydrological monitoring theory.关键词
