Resumen:

This paper presents the analysis of the evolution of the Cancun Beach Nourishment, in Quintana Roo, México. The nourishment project was based on the analysis of four beach profile sets (1985, 1989, 2000, and 11/2005, after hurricane Wilma), high resolution satellite images, wave data and native sediment samples from Cancun Beach. After Wilma the remaining sand volume was approximately 0.5×106 m3, with beachwidth of only 10 to 17 m. Although the nourishment sediment volume (2.7×106 m 3) was limited by the available federal budget, the design dry beach width was estimated to be between 22 and 28 meters. After nourishment, three beach profile sets were analyzed (April, August and November 2006), as well as the associated morphodynamic state. At present, the beach profile tends to a pre-Wilma natural slope. This process is however decreasing the dry beach width to find a stable state along the beachface. © 2007 ASCE.
