MEDINA-GONZALEZ, José Cristóbal  and  DIAZ-HERNANDEZ, Gabriel. Hybrid Maritime Climate Reconstruction and its Application to the Study of Sediment Transport in the Mexican Pacific Coast. Tecnol. cienc. agua [online]. 2014, vol.5, n.4, pp.135-144. ISSN 2007-2422.

This study analyzes the historical maritime climate on the coast of Manzanillo (Colima, Mexico), in order to reconstruct 62-year hourly wave statistics for the coastal zone. The analysis was performed by integrating different numerical tools, instrumental measurements and statistical techniques to jointly analyze the processes associated with the propagation of waves from deep waters to the coast. This information is likely to be used to drive future detailed coastal and harbour studies. The innovative contribution of this methodology includes the integration of different numerical wave propagation models and the use of algorithms to validate wave data obtained with instruments, as well as the establishment of a hybrid technique that enables performing an historical wave reconstruction with 62 years of duration in the study zone and with efficient and competitive CPU times. The proposed methodology can be easily adopted as a tool that can be commonly used for technical coastal and port engineering consulting. As an example of the use of the wave series offered by this study, a preliminary study of the short- (days to weeks) and long-term (months, seasons, years and decades) evolution of coastal dynamics is presented for the Tepalcates channel in Manzanillo, before and after its expansion.
