This paper introduces the res ults ofapplying the "Hindcast Shallow Water Waves" model to the colombian coast, sector from Galerazamba through Barranquilla.Using the wave energy and its variation in the grid points, the model was completed with a stream function, litoral drift and wave stream routines.It has been ¡den tified two sectors with the following characterístics: The first one extends from Bocas de Ceniza to Morro Hermoso, with significant depth gradients and waves approaching to the coast with high energy; the second one, fi -om Morro Hermoso to Lomarena, with smooth bathímetiy and decreasing wave energy decreasing-.It was determined northwest waves, as the responsible for the more significant erosion of the coastal
