Ítem Análisis comparativo de la ocurrencia de Avenidas Torrenciales en el Valle de Aburrá por subcuencas tectónicas(Universidad EAFIT, 2021) Albanés Atehortúa, Dhilan Durley; Osorio Betancur, Juan Pablo; Marín Cerón, Maria Isabel; Noriega Londoño, SantiagoÍtem Análisis de la torrencialidad en las microcuencas de las quebradas La Arenala y El Sesteadero (Itagüi, Antioquia)(Universidad EAFIT, 2022) Ramírez Jaramillo, Claudia Samanta; Sarmiento Contreras, Nicole Stefany; Gamboa Ramírez, Marco Fidel; Marín Cerón, María IsabelÍtem Análisis de las unidades geomorfológicas por fotointerpretación y parámetros morfométricos que influyen en la ocurrencia de avenidas torrenciales en la cuenca de la quebrada Naranjal en Quetame, Cundinamarca(Universidad EAFIT, 2024) Agualimpia Perea, María Paula; Valencia Ortiz, Joaquín AndrésNatural disasters associated with torrential floods are considered among the most destructive phenomena in Colombia due to the country’s geological and geomorphological characteristics. This study aims to identify the geomorphological parameters influencing the occurrence of these events in the Naranjal basin, located in Quetame, Cundinamarca. To achieve this, photointerpretation processes were carried out to identify geomorphological units at a scale of 1:10,000, and morphometric parameters of the basin were calculated to analyze the dynamics that generate torrential flood processes. The study revealed that the Naranjal basin is almost entirely dominated by a denudational environment, where intense weathering and erosion processes are facilitated by steep terrain and low drainage capacity. Its elongated shape and morphometric parameters indicate a slow hydrological response, which increases the risk of torrential floods during intense rainfall events.Ítem Causas de las avenidas torrenciales e inundaciones rápidas en el Departamento del Huila en los municipios de Algeciras, Campoalegre, Neiva y Rivera en febrero del 2017(Universidad EAFIT, 2019) Méndez Hernández, Leonardo; Manchego Acevedo, Sebastián; Gamboa Ramírez, Marco FidelÍtem Comparación de metodologías para la zonificación del riesgo de detalle, para los Barrios Pinares de Oriente, Esfuerzos de Paz y San Antonio en el municipio de Medellín(Universidad EAFIT, 2018) Giraldo Zuluaga, Juan Esteban; Gamboa Ramírez, Marco FidelÍtem Dendrogeomorfología aplicada a la evaluación de avenidas torrenciales en la Quebrada Juan García, afluente del Río Cauca, Andes del Norte, Colombia(Universidad EAFIT, 2021) Yepes Bonilla, Santiago; Urueña Ramírez, David Alejandro; Marín Cerón, María Isabel; Noriega Londoño, Santiago; Restrepo Moreno, Sergio AndrésÍtem El impacto de la geomorfología en la zonificación de riesgos : un estudio comparativo entre las metodologías del Ideam y SGC(Universidad EAFIT, 2024) Rojas Zapata, Jossy Esteban; N.A.Ítem Evaluación de la susceptibilidad por avenidas torrenciales en la microcuenca de la Quebrada Los Monos, municipio de Ciudad Bolívar (Antioquia) a partir del análisis geomorfológico de la microcuenca y sus depósitos asociados(Universidad EAFIT, 2018) Bedoya Giraldo, Daniel; Gamboa Ramírez, Marco Fidel; Pérez Hincapié, Ana MaríaÍtem Evaluación de la vulnerabilidad social por movimientos en masa y avenidas torrenciales en el corregimiento de San Cristóbal, Medellín(Universidad EAFIT, 2021) Londoño Torres, Nathali; Bedoya Sanmiguel, Geovany; Caballero Acosta, José HumbertoÍtem Geodiversidad en la cuenca La García como aporte a la gestión territorial en el Bosque Modelo del Valle de Aburrá(Universidad EAFIT, 2023) Rojas Serna, Juan Pablo; Ortiz Correa, Sol Celeste; Bedoya Sanmiguel, Oscar GeovanyIn this project, the geodiversity of the García stream basin (Bello) is estimated. The methods of Valentín (geostatistics) are used, modified with the diversity of morphometric indices (sensu Argyryus), validated with a preliminary inventory of Geological Interest Sites (GIS´s). The final map identified two areas with a high geodiversity index in the southeast and southwest of the basin (corresponding to the Páramo de las Baldías and Cerro Quitasol areas). This process identified that the geodiversity of the landscape analyzed is limited by tectonics, climate, and fluvial and depositional processes associated with slope instability and flash floods generated in the main drainage of the García stream. When compared to the adjacent basin to the south (Iguaná and El Hato), similar characteristics are established, and therefore shared strategies within the Bosque Modelo del Valle de Aburrá, as pilots for the future of Living Classrooms that allow the management of risk associated with flash floods, which must be articulated by the National and San Buenaventura universities, located in this territory. In this case, a first draft of an infographic is proposed for dissemination as a tool for the Social Appropriation of Geoscientific Knowledge (SAGK), with the aim of contributing to the transfer of knowledge to communities in the near future.Ítem Zonificación de amenazas por avenidas torrenciales a partir del análisis geomorfológico de los depósitos asociados y su datación. Caso de estudio : cuencas de la vertiente oriental de la Cordillera Occidental Colombiana, Andes del Norte(Universidad EAFIT, 2019) Pérez Hincapié, Ana María; Gamboa Ramírez, Marco Fidel; Bedoya Sanmiguel, Oscar GeovanyUnderstanding of debris flows and related hazards constitutes an essential ingredient in the planning and management of mountainous territories. In this work, we analyzed geomorphological, stratigraphic and hydraulic data from five watersheds located in the central zone of the Cordillera Occidental of Colombia in the Northern Andes, by estimating the flow with a return period of 100 years, increased by 40% in order to take into account the contribution of sediment and debris in the flow. Observations from the Tapartó and Farallones rivers, and La Arboleda, La Linda and Los Monos stream allowed the characterization of debris flow deposits under conditions of high slope, heavy rainfall, and an important development of soil profile. Geomorphological and stratigraphic analyses were complemented with 10Be ages Holocene ages between 6.22 ka and 8 ka (Unpublished) and 100 ± 30 and 2790 ± 30 14C yr BP . Our observations support the existence of three morphodynamic stages related to debris flow dynamics: (1) “old” stage with deposits older than 2000 14C yr BP; (2) “sub-recent” stage represented by deposits of age between 1200 and 2000 14C yr BP; and (3) “recent” stage, with lowly incised deposits and ages that do not exceed 1200 14C yr BP. Although basins studied have evidenced debris flow events of relatively high magnitude, our analyses suggest a decrease in magnitude during the last 1000 years.
