• dc.description.abstract This work explores the spatial distribution of monsoonal flooded areas using ENVISAT C-band Advanced Synthetic Aperture Radar (ASAR) in the semi-arid region of N. Gujarat, India. The amplitude component of SAR Single Look Complex (SLC) images has been used to estimate the extent of surface and near-surface water dynamics using the mean amplitude (MA) of monsoonal (July to September) and post-monsoonal (October to January) seasons. The integration of SAR-derived maps (seasonal flooding maps and seasonal MA change) with archaeological data has provided new insights to understand present-day landscape dynamics affecting archaeological preservation and visibility. Furthermore, preliminary results suggest a good correlation between Mid-Holocene settlement patterns and the distribution and extension of seasonal floodable areas within river basin areas, opening interesting inroads to study settlement distribution and resource availability in past socio-ecological systems in semi-arid areas.
• dc.description.sponsorship This research arises from an ESA Earth Observation project proposal for Principal Investigators (ESA EOPI‐ID12931) between the NoGAP Project (CaSEs‐Spanish National Research Council) and the Geomatics Division of the Catalan Telecommunications Technology Centre (CTTC). Access to ENVISAT data was granted by ESA EOPI (https://earth.esa.int). Access to ASTER images was granted by Land Processes Distributed Active Archive Center (LPDAAC)-United States Geological Survey (USGS)-Earth Resources Observation and Science Center (EROS) (lpdaac.usgs.gov). Access to GoogleEarthPro was granted via the GoogleEarth Outreach Program (earth.google.com/outreach). The research is part of the N. Gujarat Archaeological Project and the SimulPast Project (CSD2010-00034). FCC acknowledges funding from a JAE-PreDoc program (Spanish National Research Council and European Social Found). ALB has worked on this paper on contracts from the Juan de la Cierva Programme (MINECO JCI-2011-10734) and a visiting fellowship at CLISEC Klima Campus University of Hamburg. The authors wish to thank the NoGAP colleagues at the MS University of Baroda for their contribution to ongoing work. FCC specially thanks Steve Markofsky, Carla Lancelotti and the anonymous reviewers for the comments and improvements made on the original manuscript.
