The Historical, Geomorphological Evolution of the Colombian Littoral Zones (Eighteenth Century to Present)

Holocene relative sea-level changes along the Caribbean and Pacific coasts of northwestern South America

“…Earthquakes from U.S. Geological Survey's app Latest Earthquakes v. 1.3.1 (https://earthquake.usgs.gov). Geomorphology from figure 12 in Correa and Pereira (2019). Coastline data from the GSHHG Database and elevation data from the ETOPO1 1 model, both from the M_Map routine (Pawlowicz, 2020).…”

“…The tectonic framework of NW South America is a product of the junction of three tectonic plates, two oceanic (Nazca and Caribbean) and one continental (South American), which creates two subduction zones. Each subduction zone corresponds to either the Caribbean or the Pacific coast of Colombia and decisively determines the geology of each coast (Correa and Pereira, 2019). Both coasts can be considered collisional (Inman and Nordstrom, 1971).…”

Evaluación de la contracción y expansión de cuerpos hídricos lénticos bajo la influencia del fenómeno ENSO (caso de estudio. Departamento de Córdoba, Colombia)

“…Se caracteriza por su morfología aplanada, con pendientes menores del 3 %, lo cual, sumado a la variabilidad hídrica, genera problemáticas de inundaciones (Carvajal, 2009), que se amortiguan con las obras de drenaje utilizadas tanto para el manejo del régimen hídrico como para fines agrícolas y ganadería extensiva tecnificada. Las zonas cenagosas están hidráulicamente conectadas con el río Magdalena y las inundaciones se explican por la ocupación antrópica de las áreas destinadas a la regulación del régimen hídrico (Correa & Pereira, 2019). La mayoría de los cuerpos lagunares presentan procesos de sedimentación (Restrepo et al, 2018), que generan una reducción significativa del hábitat de la ictiofauna, lo que lleva a facilitar la actividad pesquera por concentrarse la población de peces en áreas más profundas (Amador, 2016).…”

An evaluation of human interventions in the anthropogenically disturbed Caribbean Coast of Colombia

“…The Continental Caribbean Coast of Colombia (CCCC) is located at the northwestern corner of South America, a region influenced by the subduction of the Nazca and Caribbean plates under the South American plate (Correa and Morton, 2010). The shoreline is 1700 km long and is characterized by an alternation of mountainous areas with deltaic plains from the three major Colombian rivers (Magdalena, Sinú, and Atrato) (Correa and Pereira, 2019;Restrepo and López, 2008). It has been shaped by the formation of thick accretionary prisms with sediment supplied from the erosion of the northern Andes, judging by the estimated rates of river's sediment load (44 Mt/yr) at the Magdalena River (Duque-Caro, 1984;Restrepo et al, 2015).…”

Interactions between geological processes and historical anthropogenic activities in coastal watersheds have resulted in unstable coastal geomorphology with environmental deterioration in several places (Correa and Pereira, 2019).
