Abstract

Using field-mapping, remote-sensing (ASTER, aerial photography), and GIS/GPS, the AA. identified and analyzed reach-scale geomorphic responses to contemporary floods along a 20-km valley length in hyperarid southern Peru. They combined these data with alluvial stratigraphy of remnant terrace patches recording late Holocene aggradation and incision. In this manner they ascertained how climate change, especially the occurence of the El Niño-Southern Oscillation (ENSO), affects the magnitude and frequency of large floods at mid-elevations of southern Peru's Atacama Desert, and they documented the geomorphic effects of large floods
