Abstract

The flood events historically have occurred in the alluvial valleys of the Region of Tarapaca due to convective characteristics of the precipitations, having negative impacts on ecosystems with great natural and cultural value, as the valley wetlands are. This research analyzed the alluvial events held on March 13, 2012 in Altuza and Iquiuca-Parca; describing the meteorological conditions of this alluvial event, obtained from the analysis of meteorological data from weather stations and interviews; as well as, estimates of changes in the area of riparian vegetation using geo-processing of satellite images and identification of disturbances in the way of life of the human populations living at or around these ecosystems. The main effects of this alluvial phenomenon were significant reductions in riparian vegetation area of both wetlands and damage to infrastructure. However, the ecological resilience of these ecosystems allowed the quick start of revegetation and self-healing processes, a very different dynamics from that experienced by the related human settlements.
