摘　　要：航道渠化工程的建设在提升航道通航等级的同时也给船舶航行带来了安全隐患。针对山区内河航道受上游电站无规律下泄非恒定流和流域暴雨汇流等因素导致的下游航道水位骤涨、流速激增、流态复杂等问题,研发了一套水上安全预测预警系统。基于物联网现场实时数据采集和历史水文资料,研究了航道地形和上下游监测站的水文相关关系,并建立了包含水位、流速、流量的水文数学预测模型,实现了准确、及时、有效的水文监测和预测预警。该系统在乌江涪陵段进行了验证和示范应用,结果表明系统监测数据准确、预测结果精度符合要求,对内河水域特别是山区河流的通航管控、防洪度汛和应急处置具有重要意义。The construction of waterway channelization project not only raises the navigation level of waterway, but also brings the hidden danger to ship navigation. The inland waterway in mountainous area is affected by the irregular discharge of the upstream power stations and the rainstorm confluence in the basin, which often results in the sudden rise of the water level in the downstream waterway, the surge of the velocity and the complexity of the flow pattern, and so on. To this end, a set of advanced scientific water safety prediction and early warning system has been developed. Based on the field real-time data acquisition and historical hydrological data, the system can analyze the hydrological correlation between the channel topography and the monitoring stations in the upper and lower reaches, and the hydrological mathematical prediction model including water level, velocity and discharge was established, which realized accurate, timely, effective hydrological monitoring, forecasting and early warning. The system has been verified and demonstrated in Fuling section of the Wujiang River. The results showed that the monitoring data of the system is accurate, and the accuracy of prediction results met the requirements. The system is of great significance to the navigation control, flood control and emergency disposal of inland waters, especially mountainous rivers.
