This first part of Hydroeurope, before the face-to-face meeting has allowed me to meet new people that are based in another university, but also to reconnect with students that I had the chance to meet during my semester in Newcastle University. 
Working and communicating via Internet only has not been always easy but it definitely helped developing communication skills, as well as management skills.
The exercices that were set up allowed be to work again with software I knew already (ArcGIS, Hec-RAS, CityCAT), as well as discovering new ones like the Mike ones.
I'm looking forward to meet my team and start the second part of Hydroeurope.
