• Runoff problems due to intense rains can affect civil constructions causing instabilities in the terrain and even damages on structures.

  Two different technologies are merged to study this phenomenon, UAV photogrammetry (Unmanned Air Vehicle) and a CFD model (Computational Fluid Dynamics) based on SPH (Smoothed Particle Hydrodynamics).

  UAV is used to obtain the topographic information about the area of study, and SPH technique is applied to study water trajectories in an extreme rain event. The use of engineering solutions to palliate flood events is also analysed.
