Cassiopée: tools for designing fish crossing devices for upstream and downstream migrations, and hydraulic calculation tools for environmental and agricultural engineering. Version 4.19.1

Cassiopée is a software dedicated to rivers hydraulics with especially some help for sizing fish passes, agricultural hydraulics and open-channel hydraulics in general. It comes in the form of independent calculation modules allowing one to solve a given problem. Calculation modules may be chained (parameters or calculation results may be linked from one module to another) in order to build complex calculation chains. Users may locally save the modules they use, in order to reuse them later. Available in French and English, “Cassiopée” is an open source and free software accessible online at https://cassiopee.g-eau.fr or as an offline application for Windows, Linux, macOS and Android.
