Remote sensing of groundwater programmes

The World Resources Institute's Earthtrends weblog has a story about NASA's Gravity Recovery and Climate Experiment (GRACE) that has predicted river flows and freshwater storage continuously since 2002. Recent data from the project showed drying along the Zambezi and Nile basins in Africa. GRACE measurements have also been able to predict water availability for farmers in the Lake Chad basin. In Botswana, the European Space Agency's TIGER Initiative project is supporting Remote sensing as a data source for surface and groundwater modelling in Botswana, a Botswana Department of Water Affairs / HOORC study of connections between Okavango swamp and groundwater, the faulting and thickness of the Kalahari sandbeds and topology and topography of the Okavango Delta's channel network.
