The University of South Florida has received a $1.5 million National Science Foundation grant which will allow researchers at the university to develop an application to identify flood risks. The app will combine volunteered geographic information and community crowdsourced data such as photos, and videos, with near real-time data on flooding. Using dynamic modeling and ...

Hurricane-related flooding can result in a slow transformation of ecosystems found on land and in water, as floodwaters can carry invasive wildlife and plant species into new regions, accelerating their spread. When invasive species spread into new areas, there can be environmental, economic and human health effects that can cost the U.S. billions of dollars. ...

Le inondazioni rappresentano uno dei disastri naturali più comuni e più impattanti a livello mondiale. Tali eventi aumenteranno ulteriormente in futuro a causa dei cambiamenti climatici, della crescita economica e dell’urbanizzazione. I ricercatori del laboratorio LSD&D (Land Surface Dynamics and Degradation) del CNR-IMAA, unitamente a ricercatori dell’Università Federico II di Napoli, propongono un approccio innovativo ...
