2D hydraulic modelling short course
“Flood risk in urban areas”
DATES 9-11 July 2018
OBJECTIVES
The training course is for professionals, researchers and students interested in the use of hydraulic
models for hydrogeological risk. The course introduces and deepens the theoretical and applicative aspects related to the use of the two-dimensional hydraulic model FLO-2D (http://www.flo-2d.com/), the state of the art in 2D hydraulic modelling for floo risk and among the most used in the world for flood risk mapping and for the engineering design of flood mitigation works. FLO-2D is approved by FEMA (USA) to support hydrologic and hydraulic modeling and simulation of flood wave propagation in urban/natural environments, to simulate debris flow, floods in coastal areas due to storms and tsunamis. The 3 days course will guide beginners and more experienced users from the early stages of learning to the use of the most advanced FLO-2D components. The first two days, all participants will be guided through a learning path to use all
the components and functionalities of the software, while the third day is dedicated to the development of projects of interest and to the specifc topic of the short course “Flood risk in urban areas”.
