Departamento de Geología; Ciencias del MarThe Arboletes-Punta Rey littoral is a 5.5-km-long stretch of coast located at the southern Caribbean coast of Colombia, 80 km by car (paved road) to Monteria. Geologically, it is located at terrains of the Sinu folded belt, a tectonically active sedimentary wedge evolving under the morphogenetic influence of numerous onshore and offshore manifestations of mud diapirism. It has a tropical climate. During the dry season (December-April), the zone is under the influences of the N-NE Trade winds that generate swells with wave periods between 6 and 9 s and significant wave heights up to 2 m. These waves are strongly modified by the serrated contours of the coastline and are rapidly eroding the beaches and littoral rocky formations of the area. During the wet season, the trade winds are replaced by lighter, 2-4 m/s, S to SW winds that generate seas with significant wave heights of up to 0.6 m. Net sand drift during the year in the area is toward the SW. The Arboletes-Punta Rey landscape is configured by an emerged marine terrace, a diapiric dome with active mud volcanoes, and by cliffs and their associated erosional features including caves, arches, stacks, and scarps of mass movements. These features are cut on sedimentary, highly weathered and densely fractured mudstones and shales, and in poorly consolidated diapiric muds. Besides its geomorphological interest, the Arboletes littoral is an interesting example of historical, kilometric-magnitude erosional coastline changes driven by the combination of natural-and man-induced causes including, in a short-term perspective, the poor geotechnical properties of rocks, bioerosion, absence of rainfall and waste waters management, strong wave action, beach sand mining, and inadequate coastal engineering practices.Ítem Arrastrando la Montaña hacia el Mar(Agenda del Mar Comunicaciones, 2017-11-01) Restrepo, Juan DaríoÍtem Assessing and managing scenery of the Caribbean Coast of Colombia(Elsevier, 2012-05-18) Rangel-Buitrago, Nelson; Correa-Arango, Ivan D.; Anfuso, Giorgio; Williams, Allan T.; Ergin, Aysen; Universidad EAFIT.

Departamento de Geología; Ciencias del MarThis study provides the coastal scenery assessment of 135 sites along the Colombian Caribbean littoral by analysing 26 physical and human factors. Sites were categorised into five classes from Class 1, top grade scenery, to Class 5, poor scenery. Fifty five percent of the investigated coastal areas were included in Classes 1 and 2, 18% belonged to Class 3 and 47% of the sites fall into Classes 4 and 5. Classification of analysed sites depends on the geological setting and the degree of human occupation. Classes 1 and 2 sites are located in natural protected areas in La Guajira and Magdalena departments. Low classification recorded at Classes 3, 4 and 5 corresponds to a progressive decrease of both natural and (especially) human parameters. Concerning coastal management issues, emphasis should be given to the upgrading of human parameters eliminating litter and sewage evidences, vegetation debris and enhancing beach nourishment works. © 2012 Elsevier Ltd.Ítem Assessing the effect of sea-level change and human activities on a major delta on the Pacific coast of northern South America: The Patía River(ELSEVIER SCIENCE BV, 2012-05-15) Restrepo A, Juan D.; Universidad EAFIT. Departamento de Geología; Ciencias del MarThis paper presents the main physical and human-induced stresses that have shaped the recent evolution of the Patía River delta, the largest and best-developed delta on the western margin of South America. During the Holocene, the Patía Delta moved southward and the northern part became an estuarine system characterized by large extensions of mangrove ecosystems. However, a major human-induced water diversion, starting in 1972, diverted the Patía flow to the Sanguianga River, and shifted the active delta plain back to its former Holocene location. This discharge diversion has led to sediment starvation of the southern delta lobe and changed the northern estuarine system into an active delta plain. In addition, coastal areas of the Patía delta subsided as a result of a devastating tsunami in 1979. Morphological changes along the delta coast are evidenced by: (1) coastal retreat along the whole delta front during the period 1986-2001; (2) coastal retreat along the abandoned delta lobe for the period 2001-2008; 56% of the southern delta shoreline is retreating and only 4% of the coast shows signs of accretion; (3) progradation of the northern delta region during the period 2001-2008; the discharge diversion of the Patía River to the Sanquianga has apparently balanced the observed trends in coastal erosion and sea-level rise (5.1mmyr -1 for the period 1984-2006, after the 1979 tsunami); (4) formation of transgressive barrier islands with exposed peat soils in the surf zone; and (5) abandonment of former active distributaries in the southern delta plain with associated inlet closure. In the northern delta lobe, major geomorphic changes include: (1) distributary channel accretion by morphological processes such as sedimentation (also in crevasses), overbank flow, increasing width of levees, inter-distributary channel fill, and colonization of pioneer mangrove; (2) freshening conditions in the Sanguianga distributary channel, a hydrologic change that has shifted the upper estuarine region (salinity<1psu) downstream; and (3) changes in vegetation succession; approximately 30% of mangrove forests in the current delta apex have been replaced by freshwater vegetation. Overall, the recent evolution of the Patía has been controlled by the interplay of (1) high basin-wide sediment load; (2) low discharge variability (Q max/Q min); (3) spatial switch of delta distributaries related to tectonic movements and subsidence; (4) a relative sea-level rise of 5.1mmyr -1 after the occurrence of the 1979 tsunami; (5) episodes of sea-level rise associated with the ENSO cycle; and (6) human-induced discharge diversion. The information presented here is valuable evidence for understanding the role of extreme events versus 'normal' conditions in creating and shaping deltas. © 2012 Elsevier B.V.Ítem Atlantic Multidecadal Oscillation (AMO) forcing on the late Holocene Cauca paleolake dynamics, northern Andes of Colombia(Copernicus GmbH, 2015-01-01) Martínez J.I.; Obrochta S.; Yokoyama Y.; Battarbee R.W.; Universidad EAFIT. Departamento de Geología; Ciencias del MarThe Atlantic Multidecadal Oscillation (AMO), is a major driving climate mechanism, in the eastern Caribbean Sea and the South Atlantic Ocean in relation to the dynamics of the South American Monsoon System (SAMS) for the late Holocene. Here we document the AMO signal in the San Nicolás-1 core of the Cauca paleolake (Santa Fé-Sopetrán Basin) in the northern Andes. Wavelet spectrum analysis of the gray scale of the San Nicolás-1 core provides evidence for a 70 yr AMO periodicity for the 3750 to 350 yr BP time interval, whose pattern is analogous to the one documented for the Cariaco Basin. This supports a possible correlation between enhanced precipitation and ENSO variability with a positive AMO phase during the 2000 to 1500 yr BP interval, and its forcing role on the Cauca ria lake deposits, which led to increased precipitation and to the transition from a igapo (black water) to a varzea (white water) environment ca. 3000 yr BP. © Author(s) 2015.Ítem Bahía de Cartagena (Colombia): distribución de sedimentos superficiales y ambientes sedimentarios(UNIV CATOLICA DE VALPARAISO, 2013-01-01) CORREA, IVAN DARIO; Universidad EAFIT.

Departamento de Geología; Ivan D. Correa-Arango (icorrea@eafit.edu.co); Johanna Prüssmann-Uribe (jprussmann@eafit.edu.co); Ciencias del MarCon el objetivo de generar información esencial para el manejo integrado y el desarrollo sostenible de la franja litoral Caribe de los departamentos de Antioquia y Chocó, se creó una base de datos espacial llamada GEOURABÁ, que recopila la información geomorfológica a escala 1:10000 de los 600km del contorno costero de esta zona, a partir de la fotointerpretación y restitución de una ortofoto de la zona tomada en el año 2009. La estructuración de GEOURABÁ consideró la inclusión de 18 geoformas costeras, las cuales fueron divididas entre aquellas que están asociadas a procesos morfogenéticos depositacionales (costas bajas) y aquellas a procesos erosionales (costas rocosas). A partir del análisis de la distribución espacial de dichas geoformas, la zona de estudio fue dividida en seis sectores según las características geomorfológicas predominantes en cada uno, de los cuales tres están asociados a procesos depositacionales y tres a procesos erosionales. En esencia, el diseño y la estructuración de GEOURABÁ se realizaron a través de los siguientes pasos: a) Definición de coberturas a cartografiar; b) Diseño del Modelo Lógico; c) digitalización de coberturas; d) Cálculo de coberturas relativas; e) Asignación de Atributos; f) Diseño de reglas topológicas; g) Estructuración de Geodatabase bajo Modelo Físico; h) Diseño de salidas de productos cartográficos. En total se cartografiaron 52882 ha de territorio emergido, donde las llanuras aluviales y las colinas fueron las geoformas más predominantes (57,18% y 19,37%, respectivamente). Ecogramas de los fondos y subfondos marinos del Golfo de Urabá revelan mayores pendientes en el costado occidental que en el costado oriental, además de otras geoformas sumergidas, como plataformas, escarpes, antiformas y diapiros. GEOURABÁ procura brindar a los entes y personas relacionados con la gestión de los recursos naturales de la zona, una contextualización de la espacialidad de los tipos de costa que se presentan en la zona de estudio y las geoformas que lo componen. Con esto se pretende contribuir a la generación de un mejor entendimiento de los diferentes factores que regulan los procesos de erosión/depositación y la vulnerabilidad de la zona frente a posibles eventos relacionados con el cambio climático global.Ítem Beach Environmental Quality(Springer, 2018-02-07) botero, camilo; Manjarres, Ganivetth; Marquez, Elien; Lopez, Juan E.

Departamento de Geología; Ciencias del MarThe analysis of interactions between human and natural systems is crucial for sound beach management practices. Those interactions can be simulated via agent-based modeling. Nevertheless, more work is needed to identify and understand model capabilities prior to societal implementations. This study presents the application of an agent-based model in the coastal town of Nags Head, NC USA. The case study focuses on the influence of storm arrival patterns and soft-engineering design alternatives on town occupation dynamics. The agent-based model consists of three interactive sub-models: (1) Natural Processes and Coastal Landforms, (2) Beach Management, and (3) Household Decisions. Modeling results indicate that sea level rise will exacerbate storm damages and could lead to a declining town population. In addition, analysis of occupancy with soft-engineering design alternatives suggests that population in Nags Head maximizes when economic benefits and protection from both, dunes and beaches, are balanced. Our results serve to exemplify the usage and capabilities of an agent-based model for beach management practices in coastal towns subjected to storms and sea level rise. Application of the model provides valuable insights of the system that can ultimately be used by decision-makers and town managers.Ítem Caracterizacion Del Mercado De Alimentos De La Localidad De Usme(Fondo De Publicaciones Universidad Distrital, 2007-02-01) CORREA, IVAN DARIOÍtem Caribbean Coast of Colombia(Springer Netherlands, 2010-01-01) Arango, I.D.C.; Morton, RobertÍtem Cartagena Bay (Colombia): Superficial sediments distribution and sedimentary environments(UNIV CATOLICA DE VALPARAISO, 2013-01-01) Restrepo, J.C.; Franco, D.; Escobar, J.; Correa, I.D.; Otero, L.; Gutiérrez, J.; Universidad EAFIT. Departamento de Geología; Ciencias del MarWe studied the spatial distribution and textural characteristics of 234 surface sediment samples from the Bay of Cartagena, Colombia, to understand sedimentation processes over the last few decades. We used three discriminant functions to characterize depositional environments and to differentiate among: (i) beach deposits and sediments of high-energy, shallow marine environments, (ii) fluvial deposits and sediments of shallow marine environments, and (iii) fluvial deposits influenced by turbidity currents. The predominant sediment type is a medium-size (5.35 ± 1.2 f), poorly sorted (s = 1.63 ± 0.8) mud, with a noticeable asymmetry (Sk = -0.052 ± 0.2) and kurtosis (k) of 0.84 ± 0.4. There were two main superficial sediments types in the Bay of Cartagena: (1) sediments of high-energy, shallow marine environments with high fluvial influence, and (2) turbidity current deposits with high fluvial influence. Sediments with the lowest sand content (<5%) are located along a latitudinal axis running from the Dike Channel prodelta to the western end of Tierrabomba Island. The CaCO3 content of the sediments is <10%. Autogenous calcareous sediments are covered by fine terrigenous sediment transported through the Dike Canal, which has a more active and dominant role in the Bay's sediment deposition than previously reported.Ítem Chapter 1 Satellite-Based Estimation of Water Discharge and Runoff in the Magdalena River, Northern Andes of Colombia(Springer International, 2016-10-01) Restrepo, Juan DaríoÍtem A Classification System for Colombian Wetlands: an Essential Step Forward in Open Environmental Policy-Making(Springer Netherlands, 2019-01-01) Ricaurte L.F.; Patiño J.E.; Zambrano D.F.R.; Arias-G J.C.; Acevedo O.; Aponte C.; Medina R.; González M.; Rojas S.; Flórez C.; Estupinan-Suarez L.M.; Jaramillo Ú.; Santos A.C.; Lasso C.A.; Nivia A.A.D.; Calle S.R.; Vélez J.I.; Acosta J.H.C.; Duque S.R.; Núñez-Avellaneda M.; Correa I.D.; Rodríguez-Rodríguez J.A.; Vilardy Q S.P.; Prieto-C A.; Rudas-Ll A.; Cleef A.M.; Finlayson C.M.; Junk W.J.; Universidad EAFIT. Departamento de Geología; Ciencias del MarKnowledge about the distribution and diversity of wetlands has become an essential tool for environmental management and policy-making. Yet, while recent estimates indicate that 27% of the area of Colombia is covered by wetlands and despite a number of regional studies, information about the diversity of wetlands nationally is scarce. In response, we present a national wetland classification system that is based on an ecological approach, from the perspective of wetland scientists, and which builds upon the assumptions underlying the flood pulse concept and hydrogeomorphic approach. Thus, the approach and structure of the Brazilian wetland classification system are used, with geomorphological adjustments made according to Colombia’s topography. The classification is hierarchical, multi-scale, functional, and organized according to four levels (system, macroregion, subsystem, and class), with the wetland diversity of Colombia represented nationally by 89 macrohabitats across marine-coastal, inland, and anthropogenic systems. The primary purpose of this classification is to provide integrated and organized information on the distribution and diversity of Colombian wetlands that will serve as a baseline for transparent environmental policy-making. © 2019, Society of Wetland Scientists.
