Hi, another one,
http://hydra-software.net/
the qgis plugin helps a lot in creating the a correct mesh with 1D /2D
areas. The flood modeling algorithm is freeware, not open source (yet?).
I've been really impressed by the qgis plugin features and the accuracy in
territory segmentation it allows.
Best regards,
Régis
