Interpretación Geomorfológica y morfométrica del abanico aluvial del flanco Occidental de la cuenca de Catamayo

Abstract

Abstract: This research presents the geomorphological and morphometric characterization of the alluvial fan on the western flank of the Catamayo Basin to assess its hazard. The methodology integrated spatial analysis in ArcGIS with the surveying of stratigraphic columns in areas such as Nambacola. A direct correlation was established between the architecture of the sedimentary columns and the identified geomorphological units, validating the morphometric indices through observation of fan facies and depositional processes in the field. The results reveal a close relationship between depositional dynamics and regional tectonic control, allowing for the zoning of areas susceptible to geological processes. This work provides a robust technical basis for risk management, demonstrating that the integration of Quaternary strata data and quantitative parameters is fundamental to understanding the evolution and current behavior of fan systems in active environments and their potential hazards. The research constitutes a critical contribution to land-use planning and the safety of human settlements in the basin.
