SummaryWe will conduct research to assess the interferometric capabilities of TerraSAR-X data to detect and measure deformation associated with salars. Erosion processes, sediment transport, and deposition-aggradation cycles are primarily controlled by rainfall and river discharge. In order to understand how rainfall, and in particular hydro-meteorological extreme events (> 90thpercentile) modulate erosive processes in tectonically active mountain belts, this proposal focuses on the South-Central Andes of NW Argentina. Several studies during the past 15 years have indicated that the interaction between deformation, topographic construction, climate, and erosional processes may control the structural evolution of orogens. Accordingly, sustained focussed precipitation and erosion may ultimately influence the kinematics and loci of tectonic activity in orogens. We will utilize advanced InSAR time-series analysis to detect and measure ground deformation overtime for the Salar de Pocitos in Argentina.
