The works presented in this document are developed under framework of the collaboration agreements signed between the Centro de Estudios Hidrográficos (CEDEX), FLUMEN research group (UPC), GEAMA (UdC) and CIMNE. The result of this agreement is a numerical simulation cade that put together the experience o/ all the partners in the different aspects of river dynamics. The new tool called lBER, is aimed to the hydrodynamic and morphological simulation of rivers flow. Nowadays IBER includes a hydrodynamic module that allows 2D modellization of rivers, a turbulence module and a sediments transport module that considers both bedload and suspended salid discharge. IBER offers, as well, a user friendly interface that takes profit of the capabilities of GiD, both in pre and post process.
