中国科学院地理科学与资源研究所莫兴国研究团队提出一个新的河道水位遥感反演方法新近在Remote Sensing of Environment 发表（图）
莫兴国 水位遥感 水文 水资源管理
2024/1/14
河道水位是洪水预报的关键变量，也是地表水资源供给能力的晴雨表。河道水位一般通过水文站实测，但由于全球水文站网密度稀疏，流域内存在大量的无河道水位观测断面，成为全流域精准防洪和水资源管理的硬件短板。测高卫星观测的水位数据可以覆盖全河道，这有力地提高了水位数据的空间代表能力。然而测高卫星要么空间分辨率太粗糙，无法识别小于80米的窄河道的水位；要么回访周期太长，无法探测河宽的关键时间变化节点。因此如何获...
