Introduction
I read Hydraulics and Hydrology in Italy both as a graduate and a PhD. In my research activities I have been developing methods and algorithms to retrieve quantitative information from remote sensing images acquired from both airborne and satellite platforms. I am also a Professor on application of remote-sensing techniques to hydrology and water quality, on GIS applications in hydrology and on Coastal Engineering.
