摘要(Abstract)：

针对无资料蓄滞洪区水动力模拟中常见的浅水区边缘扩算与深水区数值高估现象，以海河“23·7”流域性特大洪水期间启用的东淀蓄滞洪区为例，提出了一种融合多源遥感数据的分段阻尼校正方法(SDCM),针对不同水深区间的误差特征，构建了分段式非线性后处理校正框架：利用Sentinel-1/2遥感水陆动态边界作为空间约束，识别浅水区异常淹没；引入稀疏实测锚点数据，对深水区进行非线性阻尼修正。结果表明，SDCM能够较好缓解模拟中的双重偏差；相较于传统全局线性校正方法，其在浅水区改善和深水极值约束方面表现出更均衡的校正效果。经校正后，浅水异常淹没得到显著抑制，深水区极值相对偏差收敛至1.1%,全域平均修正幅度为0.81 m。该方法适用于高精度资料缺乏地区的洪水模拟校正，可为电力设施等关键基础设施的洪涝灾害测绘提供技术参考。
