Cancun beach is one of the most important tourist resorts on the Mexican coast, and is of prime importance to the local and national economies. As a result of the intense use of the beach andthe unavailability of sand reserves, the extreme weather events that occur in the region (hurricanes) have permanently damaged the beach. Over the last two decades several strong hurricanes severelyweakened the system, but hurricane Wilma, October 2005, caused devastating erosion to the beach. After Wilma, an emergency nourishment project was implemented pumping a volume of 2.7 millionm3 of sand onto the beach. Clearly, the sand used for the nourishment has a different shape factor, diameter distribution and density property compared to the native sand. The main goal of this paper isto characterize and compare the fall velocities of sand samples taken in and around Cancun. The settling velocities obtained for several samples were compared with the empirical formulationsproposed by various authors. The influence of several parameters measured in the laboratory is discussed and a new formulation is presented. |
