Abstract: Many satellites have been launched into space to collect information about the Earth's surface for decades. Water surface width of large rivers is one kind of hydraulic information that can be extracted from satellite images. In this study, an approach that contributes river width data derived from satellite images to retrieve river discharge in remote reaches of large river basins through rainfall-runoff modeling is proposed. By connecting rainfall-runoff model with hydraulic geometry, instead of in situ gauged discharge data, rainfall-runoff model is calibrated against remotely sensed river width. A case study is carried out by applying effective width of river water surface derived from Japanese Earth Resources Satellite-1 (JERS-1) Synthetic Aperture Radar (SAR) images to calibrate HYMOD rainfall-runoff model at Pakse gauging station in the Mekong River Basin. The results show an acceptable accuracy for discharge estimation. And uncertainties of the proposed method were also discussed through the case study.
