Description :
By using remote sensing techniques including satellite synthetic aperture radar (SAR), Landsat TM, and laser altimetry in combination with field-based methodologies, the AA. discuss the geomorphic signature of this catastrophic flood that generated extreme peak discharges. The broader spatial dimension provided by remote sensing techniques, combined with pre- and post-jökulhlaup topographic information across the sandur, provide the opportunity to explain the impacts of this flood in relation to the late Holocene depositional history of the sandur and the hydrologic conditions occuring during the event itself.
