在黑叶河，自2001年以来，对达希代拉大坝和乌纳祖基大坝进行了协调冲沙和泄沙。从输沙系统泥沙综合管理的角度来看，对江河水库泥沙输移过程中的输沙量和输沙量进行监测十分重要。介绍了乌纳祖基大坝2015、2016年冲沙泄洪运行期间高悬移质含沙量的连续测量结果。这些数据是通过潜水式悬沙浓度测量系统(下称潜水式SMDP)获得的，该系统是为水下而设计的。测量数据与人工采样具有良好的相关性，并有效地利用在最关键的时间段对闸门运行进行实时控制，在自由水流开始冲沙之前产生极高的浓度。
In the Kurobe River, coordinated sediment flushing and sediment sluicing of Dashidaira and Unazuki dams have been executed since 2001. From the view point of the comprehensive sediment management in the sediment routing system, monitoring of quantity and quality of sediment transport during these events in rivers and reservoirs is very important. This paper shows the results of continuous measurement of high suspended sediment concentration during sediment flushing and sluicing operation of Unazuki dam in 2015 and 2016. These data have been obtained by submergible type of Suspended Sediment Concentration Measuring System with Differential Pressure Transmitter (hereinafter we call ‘submergible type SMDP’), which is designed to be placed underwater. Measured data have good correlation with manual sampling and effectively utilized to control gate operation by real-time basis during the most critical timing producing extreme high concentration just before free flow starts for sediment flushing.
