Through photo interpretation and field work is possible to realize that during the period, the essential forms of the estuary haven't manifest significant changes, on the other hand, estuarine complex such as the estuarine lagoon, sandy beach and dunes have presented modifications. The most significant morphological elements in order to understand these phenomena of changes have been the dynamics of waves and their spatial correlation with the width of the surf zone and dune continuum. The basic shapes present stabilization in their dynamic, which allows us to consider the estuarine system of Copiapo, a paleoestuario.

Central Chile JF - Revista de geografía Norte Grande N2 - In the Aconcagua basin the modernization and intensification of land use have resulted both in an agricultural conversion, and the increase in area cultivated. This process has been very intense as far that have entered new areas beyond the limits of the valley and towards sloping ground. This signals changes in land use over the vegetation coverage models. The analysis of the geomorphology of the coastline in detail, accounts for the occurrence of transformations on the beach and dunes that are spatially less significant, but evolutionarily important, since they show a sediment feeding, which could be correlated with changes in vegetation cover in the basin KW - Land use change KW - sediment input KW - coastal sand dunes Y1 - 2011 SN - 0718-3402 IS - 50 SP - 187 EP - 202 PB - Instituto de Geografía, Pontificia Universidad Católica de Chile CY - Santiago ER -
