The rising water from the river Bidouze flooded about 40 roads in both cities and after a dike alongside the train tracks in Mont de Marsan broke, the floodwater threatened to paralyze the train traffic in and around the city. However, Sécurité Civile managed to deploy 400 meters of the
NoFloods Mobile Barrier in under one hour, which successfully held back the floodwater. The water that had already reached the train tracks was simply pumped back out,whichallowed trains
to continue running without interruption. The deployment of the NoFloods Barrier in Mont de Marsan was covered by the French national TV news, where it was praised for its simple and very quick deployment.
