- Shoreline changes in Concón and Algarrobo bays, central Chile, using an adjustment model Carolina Martínez Ciencias de la Tierra embayment shoreline headland bay central Chile Adjustment models for both Algarrobo and Concón bays, central Chile, are presented herein; the resultsshow a nearly logarithmic spiral shape for the shore. Spatial-temporal variations in the shorelines of both bays were foundbased on aerial photographs from different years. The results indicate important variations in the relative position of theConcón Bay shoreline between 1945 and 2006, with extreme oscillations (-368 to 123.8 m) only occurring in the proximalzone, where the Aconcagua Estuary is located. On the other hand, the spatial-temporal variations in the AlgarroboBay shoreline between 1967 and 2006 are moderate (131 in the proximal and -73 in the distal zone). Whereas ConcónBay exhibits a stable state of equilibrium for the past 60 years, if the estuary zone is excluded, Algarrobo Bay presentsa stable state with a tendency for growth in the proximal zone and retreat in the distal zone. The results are discussed interms of coastal changes associated with highly urbanized shorelines and applications for coastal area management thatare derived from the models. 2007 artículo científico 0716-1069 https://www.redalyc.org/articulo.oa?id=45635210 en http://www.redalyc.org/revista.oa?id=456 Investigaciones Marinas application/pdf Pontificia Universidad Católica de Valparaíso Investigaciones Marinas (Chile) Num.2 Vol.35
