River runoff parameters are the basic data used for surface water resource assessment, global change monitoring and ecological environment protection. The traditional river runoff parameters are obtained by gauging stations. However, due to the economic and political reasons, in recent years, the global runoff gauging stations has gradually decreased. As the increasing demand of regional and global hydrological monitoring network construction for global change research, the issues of limited gauging stations and a variety of data formats become apparent. Over the past 15 years, the research and application of satellite remote sensing technologies to  river runoff monitoring have made it possible to resolve the above-mentioned issues. The paper summarized the progress of the methods and technologies about the river runoff remote sensing monitoring including the ground high-frequency and low-frequency radar, aerospace radar and multi-spectral satellite remote sensing, and introduced the dynamic monitoring results of the world′s large river runoff and lake water, and the future research plans. It pointed out that, before the hydrological remote sensing satellites with the capability of monitoring the earth′s surface in all weather conditions, day or night, and with high spatial and temporal resolution, was launched, it is necessary to make great use of the field remote sensing experiment to improve the river runoff monitoring methods, and to integratedly apply the current high spatial and temporal multi-spectral and microwave remote sensing data to monitor the river runoff.
