"Sac de crue" currently offers several apps in html and Python, detailed in wiki pages for professionals, and is presented for the general public in the website of the association EauDyssée.
More detailed explanations will be gradually added the the wiki pages of this english version gitlab.

| What can marbles in a bag tell us about flood hazard ? Is drawing the only red marble out of 100 analoguous to experiencing a 100-yr flood ? Almost, but not quite... Then, once we know what a return period means, how can we guess the probabilility to be flooded on a duration of several years ? Let's draw series of marbles - successively. How does the outcome vary from one series to another ? Let's talk about variability. |  |
