Modelo de evolución de playas considerando planta y perfil, en escalas de medio a largo plazo

Résumé

The objective of this thesis is to develop a new equilibrium-based shoreline evolution model integrating planform and profile in the medium to long-term scales. From the proposed research, first the applicability of mid-resolution satellite-image processed with a subpixel algorithm was explored, for its use in the calibration and validation of equilibrium-based shoreline evolution models. Then, a new equilibrium-based shoreline evolution model considering the variability of the beach profile volume was developed, considering the temporal variation of the equilibrium energy function (sediment gain or loss). Later, a new model for embayed beaches based on cross-shore and planform equilibrium models applicable for cross-shore migration was developed. Finally, a new empirical equilibrium-based shoreline rotation model was developed assuming that the rotation movement is induced by the incoming wave power and direction.
