What is it about?
Main rivers have been traditionally linked with important human settlements through history. The increasing development of the cities and the dynamism of these media demand the use of multidisciplinary approaches to characterize the drainage network evolution in relation with urbanized areas. In this study, we report the vertical ground motion in the city of Sevilla (southern Spain) between 2003 and 2010, through the analysis of the results obtained with the multi-temporal InSAR technique. we have characterized the geotechnical parameters of the fluvial sediments in the less and more subsiding sectors.

Why is it important?
Derived results are, therefore, valuable for implementing appropriate urban planning strategies that may consider the InSar technique as a complementary tool to unravel the subsidence tendency of cities located over non-consolidated fluvial deposits.
Perspectives
The research team continues in this line, developing methodologies for the study of the geotechnical behavior of civil engineering infrastructures that improve future projects.
