SummaryWe propose to use X-band Radar and inSAR methodology to measure the size of the discharge cone associated to the rapid depletion of alluvial and coastal aquifers in the Persian Gulf area in three zones including Kuwait, United Arab Emirates (UAE) and Qatar. InSAR observations will be combined with low frequency airborne sounding radar data (acquired separately under separate NASA funding) to correlate the observed Line of Sight (LOS) displacements arising from aquifers’ discharges and recharges and the depth variation of the water table as observed from sounding radar data and from in-situ well logs. The approach will help us better understand the dynamic and the extension of these aquifers and the associated effects on surface topography. Moreover we will use the SAR scenes to map the paleo-drainage networks in these areas that lead to the formation of alluvial aquifers (e.g.sites in Northern Kuwait and Qatar). In particular we will be studying surface roughness variations at the beds of paleo-drainage networks. By characterizing the fossil aquifer dynamic in hyper arid environments and how they respond to climatic changes using TerraSAR-X data we contribute to two of the mission main objectives: (1) Understanding The Water Cycle and(2) Characterizing the Impacts of Climate change. Scientific writing about SAR observations will be submit in a Peer review journal such EPSL or JGR. This work will be funded under NASA research Grant.
