摘要
梧州水文站上游约2000 m是干流浔江与支流桂江交汇处,下游180 m为云龙大桥,水流形态复杂。为了解决高洪以上水位级流量在线监测难题,2019年7月底在梧州水文站安装侧扫雷达开展比测试验。通过分析侧扫雷达表面流速的准确性、建立断面平均流速与侧扫雷达表面流速模型及水量计算分析来研究侧扫雷达在线流量监测系统在西江梧州水文站河段的适用性。目前已收集到水位2.93~10.79 m、流速0.33~1.19 m/s的比测资料,分析结果表明:侧扫雷达在线流量监测系统可在梧州水文站应用。
Xunjiang River and Guijiang River intersects about 2000 m upstream of Wuzhou Hydrological Station,180 downstream of the station is Longyun bridge,which lead to complex flow pattern.In order to solve the on-line flow monitoring problem at level above high flood,side scan radar were mounted at Wuzhou station in July of 2019 to conduct comparative test.The accuracy of surface flow velocity out of radar was analyzed;cross-sectional average velocity and radar surface velocity model was set up;water quantity calculation and analysis were conducted,based on which the applicability of side scan radar on-line flow monitoring system at Wuzhou station on Xijiang waterway was studied.The comparative test data of velocity within 0.33-1.19 m/s corresponding to level of 2.93-10.79 m had been collected and analyzed.The results of analysis demonstrate that side scan radar on-line flow monitoring system is applicable for Wuzhou station.
