Résumé
"Socially and culturally, the Laguna Encantada (‘Enchanted Lagoon’) in Guelatao de Juárez, Oaxaca state, is one of the most important bodies of water in Mexico. In this study morphometrical findings and an historical analysis of morphological changes over the past 400 years is presented. The objective was to provide data about the changes of the Laguna Encantada that will contribute to understand interactive processes between nature and society. The study was performed from a landscape perspective, integrating batimetrical parameters, superficial and subsurface morphometrical dimensions, and historical modification processes were also analyzed utilizing satellite photography and repeat landscape images. The results indicate that the system called the Laguna Encantada is a circular lake with a convex tray of 7.20m maximum depth, an area of 11,610m2 , and a maximum length of 131m. Between 1960 and 2010, there was an increase in those dimensions. It has experienced diverse transformations in its dimensions, the most notable happening in the 20th century. Hydrologic and morphometric information, and recent transformations, along with landscape reassessment in relation to scenery and eco-tourism, are deemed necessary for the management of the system."
