COMPARATIVE GEOMORPHOLOGICAL ANALYSIS APPLIED TO THE HAZARD ASSESSMENT BY DEBRIS FLOWS IN THREE WATERSHEDS OF THE CENTRAL CORDILLERA OF COLOMBIA
The watershed of the Tapartó and Farallones rivers and the La Arboleda stream in the central zone of the Colombian Cordillera Occidental, are characterized by presenting important debris flows events at historical level, in turn, show geomorphological evidences that suggest a complex dynamic associated with the conditions of high slope, high rainfall and a soil profile with an important development.
The geomorphological analysis carried out in these watersheds allowed the recognition of different levels of deposits, in addition to the stratigraphic characterization of the same. Likewise, radiocarbon dating allowed to establish ages between 100 +/- 30 and 2010 +/- 30 years for the different levels of deposits characterized. The integration of geomorphological, stratigraphic information and radiocarbon dating allowed to differentiate the debris flows dynamics of each of the basins and suggests the establishment of three phases, the first of them of an ancient character (with deposits older than 2000 years), a sub-recent dynamic (represented by levels between 1500 and 2000 years) and a current dynamic, with low incised deposits systems and ages not exceeding 500 years. Finally, it was established that, although these basins have a great potential for the generation of debris flows events of significant magnitudes, the deposits show a tendency to decrease their magnitude in the last 1000 years.
These analyzes and their results constitute an input for the construction of knowledge in relation to the understanding of the phenomenon in tropical environments and the generation of elements that allow addressing the problem in other sectors with similar characteristics in the country.
