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营的空间重力卫星任务中近实时数据的效用，以量化和跟踪澳大利亚的洪水。通过分析卫星数据以及与降雨，河流和常规水文建模的观察到的信号融合，它预计将创造出有关土壤水分和洪水流动的新知识。预期的结果包括通过包括从近实时观察结果获得的水信号的信息来改善水文模型的能力。这将提供重大的好处，例如更准确的土地饱和图以及对径流和洪水风险的更好预测。
