July 9-11, 2018: 2D hydraulic modelling Short Course in Perugia

Home / Portfolio / July 9-11, 2018: 2D hydraulic modelling Short Course in Perugia

2D Hydraulic modelling short course
“Debris flow, Sediment Transport and Dam Break”





July 9-11, 2018




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 hydrogeological 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 specific topic of the short course “Debris flows, sediment transport and dam break”
