2013年黑龙江大洪水遥感监测分析

Satellite Remote Sensing Monitoring and Analysis of Heilongjiang River Flood in 2013

2013年汛期,黑龙江流域发生自1984年以来最大洪水,下游发生超100年一遇特大洪水,干流萝北至同江河段多处堤防出现险情。利用多源卫星遥感数据,对2013年黑龙江大洪水汛情和灾情进行了持续动态监测和分析评估,准确、及时、全面地跟踪了整个流域洪水的演进过程及发展变化趋势,特别是解决了无观测资料情况下对洪灾的监测预测难题。

The China-Russian bordering Heilongjiang River experienced the worst flood since 1984, with a return period excess 100 years in the lower reach. Dike breaches occurred from Luobei County to Tongjiang City. The multi-satellite remote sensing data show the capability for continuous and dynamic flood monitoring, providing near real-time and effective flood information for decision making and disaster management. It demonstrated that satellite remote sensing has been a viable alternative or supplement to in-situ observations especially over the ungauged area.
