The calculators for hydraulics have evolved and are now replaced by the Cassiopee software available online : https://cassiopee.g-eau.fr

The Cassiopée software was developed by the ecohydraulic R&D pole gathering OFB (French Office for Biodiversity) and IMFT (Fluids Mechanics Institute of Toulouse) and by UMR G-EAU (Joint Research Unit "Water Management, Actors, Territories").

It includes tools for designing fish crossing devices for upstream and downstream migrations, and hydraulic calculation tools useful for environmental and agricultural engineering.
