Abstract
FORERO-OSPINO, Oscar Enrique and DUARTE-DELGADO, William Fernando. Identification and characterization of the geomorphology (geomorphological environments and units) of the Sheet 121 - Cerrito, Colombia, applied to landmass movements, scale 1:100.000. bol.geol. [online]. 2019, vol.41, n.2, pp.35-45. Epub May 30, 2019. ISSN 0120-0283. https://doi.org/10.18273/revbol.v41n2-2019002.
This research focuses on the identification of geomorphological units based on geological evolution in the Sheet 121 - Cerrito, Santander, Colombia, using the geological evolution as criterion. In addition analysis of landmass movements is included showing active geomorphology (morphodinamics) such as pluvial erosion, hydrodynamic scour, and creep, among others. These processes affect rocks depending on their physical and chemical properties with the generation of soils producing favorable characteristics for accumulation or high content of water in their structure (clay soils). As consequence of high rainfalls and large volumes of fluids are produced movements such as flows and slides. The development of maps showing landslides is useful to mark off hazard and susceptibility zones by landmass movements considering its geomorphological features and its distribution in the area of study.
