This project aims to assess the utility of near-real-time data from the currently operating space gravity satellite mission to quantify and track flood waters in Australia. Through analysis of the satellite data and fusion of observed signals with rainfall, river flows and conventional hydrological modelling, it expects to create new knowledge of soil moisture and movement of flood waters. Expected outcomes include a capability to improve hydrological models by including the information of water signals obtained from the near-real-time observations. This should provide significant benefits such as more accurate land saturation maps and better predictions of runoff and flood risk.

该项目旨在评估目前运行的空间重力卫星使命的近实时数据在量化和跟踪澳大利亚洪水沃茨方面的效用。通过对卫星数据的分析以及将观测信号与降雨量、河流流量和常规水文模型相结合，预计将获得有关土壤湿度和洪水沃茨流动的新知识。预期成果包括通过纳入从近实时观测中获得的水信号信息来改进水文模型的能力。这将带来显著的好处，如更准确的土地饱和度图和更好的径流和洪水风险预测。
