Main project: Development, diffusion and set up of a collaborative project for the development of applications aimed at flow measurements and simulations in rivers.
Funding: Sandra Soares-Frazão
Supervisor(s): Sandra Soares Frazao

The contribution consists in the set-up of a sharing platform dedicated to applications for flow measurements and simulations in rivers under an open-source license. In the same time, I will provide collaborative and management tools to organize and share code developed in the team for several flows : hydrodynamics, sediment transportation, morphological evolution, urban floods,…
