Title: An Improvement Method to Study the Spatio—Temporal Dynamics of Rancho Luna Beach´ Shoreline Applying Remote Sensing Tools
Abstract: The beaches constitute a very fragile and limited resource representing a huge weight on the economies of many countries and regions of the world. Constant monitoring of them is necessary because they are very fragile ecosystems but they are very expensive so the remote sensing techniques has proven to be an efficient alternative to assess the accretion-erosion processes. This research evaluates the spatial dynamics of the Rancho Luna beach shoreline by analyzing five the SPOT satellite images every two years, in the same seasonal period. A supervised classification was performed by the Maximum Likelihood method and 70 transects were defined every 10 m for the 700 m length of shoreline. An improvement of the traditional method to create the perpendicular transects is proposed and the methodology for this is presented. An erosive process is observed in 86% of defined transects and a loss of 8007.81 m2 of the beach area. The results of the study are in correspondence with previous studies based on direct measurements of beach profiles.
