Computer models are used to simulate aspects of the natural world, such as the water cycle within river basins. Satellite observations can be used to improve the accuracy and spatio-temporal detail of hydrological models. Satellite and ground observations are combined with the model in a ‘data cube’ to derive parameters such as river discharge rate. The data cube can be used for water resource management and to identify locations and times of risk.
