. Using High Resolution Digital Elevation Models for Small Scale Inundation Studies of Coastal Megacities

Abstract
In this poster we use high resolution digital elevation models (DEMs), combined with a global mean sea surface model to characterize areas in coastal megacities at risk for inundation due to sea level rise. We provide results using satellite measurements only, allowing us to perform these studies for many coastal cities across the entire world, particularly in regions where geodetic infrastructure is sparse or even non-existent. In order to validate the use of the mean sea surface model, we compared it with a global dataset of 302 tide gauges, showing a near zero-mean difference, with an RMS of 27 cm.
