Abstrakt (česky)
   The relatively steady system of the Sechura desert is affected by a phenomenon that is known as the El Nino/Southern Oscillation (ENSO).The wet weather conditions normally present over the western Pacific move to the east and bring heavy rainfalls that, as a consequence, bring enormous water inflow for the Chira and Piura rivers.River fluvial systems respond to these extremes by unpredictable changes in the geometry and positions of the river channels.The present study covers a total area of 20 000 km2 and combines various mapping techniques while utilizing diverse EO data: multitemporal Landsat scenes from 1973, 1984, 1985 and 2000-2001; 6 scenes of ASTER acquired during 2006-2007.Multitemporal Landsat scenes were used to reconstruct the fluvial networks of the Chira and Piura Rivers and to classify surface material in the desert environment.Analysis of ASTER TIR scenes allowed creation of a mineral abundance map of quartz-rich, carbonate-rich and gypsum-rich sediments
