SISYPHE, GAIA & SEDI-3D | CREST project

Information

http://www.opentelemac.org/index.php/modules-list/164-sysiphe-sediment-transport-and-bed-evolution

Sisyphe is a sediment transport and morphodynamic model. SISYPHE is a sediment transport and bed evolution module of the TELEMAC-MASCARET modelling system. SISYPHE can be used to model complex morphodynamics processes in diverse environments, such as coastal, rivers, lakes and estuaries, for different flow rates, sediment size classes and sediment transport modes. SYSIPHE will be replaced by GAIA & SEDI-3D in the new releases starting 2020.

Developed by: TELEMAC consortium under coordination of LNH-EFD (Chatout, France)
