Method of littoral sediment transport estimation in sand beach Método para la estimación del transporte de sedimentos litoral en playas de arena

Today, beaches are in a critical situation due to erosion. These places are very significant for the economy and tourism. For this reason is important to know the rate of sediment transport and the behavior of it. This work proposes a methodology based in used international models to estimate magnitude and direction of the littoral sediment transport. The method that expose propose to use Longuet-Higgins's velocity formula in Bijker's method to obtain cross shore distribution of alongshore sediment transport. Even, values in surf zone are required for this, it can solve through methodology shown in Coastal Engineering (2000) of Technical University of Delft. Calibration is make for two study. La Ingeniería Costera se subdivide en tres categorías: Puertos, Morfología y Offshore. Siendo el campo de la morfología el más extenso y el que interviene en los demás. En la morfología costera se estudia la interacción entre el oleaje, la corriente y la costa, lo cual provoca un movimiento de la arena (transporte de sedimentos) y eventualmente cambios en la costa.
