摘要
研究咸潮入侵实时、准确预警预报问题。目前咸潮入侵多为实测数据,没有相应的预警预报系统,无法实时、准确地预警咸情。为解决上述问题,提出可变河口盐度仿真迭代预警模型并给出实现算法,只要获取河口盐度和径流量等几个参数就能快速准确预警当地咸潮入侵盐度和入侵距离,解决了当地咸潮入侵预警预报实时性和准确性的技术难题。经过仿真证明,可变河口盐度模拟迭代预警算法误差较小,能快速、准确地监测预警咸潮入侵情况;基于算法开发设计的咸潮入侵预警预报信息系统在线预警形式直观,实现了珠三角地区咸情的实时、准确预警,证明了预报系统的有效性。
The online warning and forecasting of saltwater intrusion are studied. Currently, saltwater intrusion model can only display the measured data, and the timely warning and forecast can not be achieved. To solve the a- bove problem, this paper presents a variable estuarine salinity simulation model, and gives the iterative algorithm of early warning. As long as accessing parameters, such as estuarine salinity and runoff etc. , accurate early warning of the salinity of local saltwater intrusion and the largest local saltwater intrusion distance can be rapidly realized, which solves the technical problems of local saltwater intrusion forecasting. Experimental results show that the proposed sim- ulation iteration variable salinity estuary warning algorithm has relatively low error, and can accurately monitor saltwa- ter intrusion. The saltwater intrusion forecasting information system developed basedon the algorithm has visual online early warning pattern. Using this system, the early-warning of saltwater intrusion can be electronized.
