    Estimation of Water Erosion and the Transportation of Sediments in the Upper Basin of Cuxtepeques River, Chiapas, Mexico

    Changes in land use and increased intensity of rainfall are factors of greater influence that accelerate the soil erosion process. The application of basin scale sedimentological models integrated to Geographic Information Systems (GIS), is a tool that allows the definition of critical zones, and of this the establishment of measures of control of processes of production and transport of sediments. This study evaluates the water erosion using the Universal Soil Loss Equation (USLE), five scenarios were studied: corresponding to the start of operations of the El Portillo II (1980) dam, and the before and after the two extreme events in the basin (September 1998 and October 2005). The transport of sediments was evaluated by regression, using full annually records (eight years) of flows of two gauging stations in the basin. Overall, variations in erosion rates were observed with changes in the vegetal coverage and statistical homogeneity in the gauging data, which allowed adjust them to a regression model, with correlation coefficient upper to 88%.

    Identificación de zonas estratégicas para el desarrollo competitivo del turismo en Medellín
    (Universidad EIA, 2014) Gaviria Ortiz, Juan Camilo; Londoño Zuleta, Juan Camilo; Márquez Godoy, José Ignacio
    This work is about finding the best zones, in order to develop touristic projects at Medellín city. During the research the investigators found 3 different zones where the tourism takes place. The zones are: Downtown, Laureles and Poblado. To have a better coalification the researchers picked 5 variables that impact the tourism directly, in order to determinate easily which of the 3 zones has the conditions or characteristics to develop and continue growing the tourism business. Those variables are: transportation, travel agency, touristic places, gastronomy and hotels. The tool that was chosen by the investigators, was an interview which was applied to some experts, who work in the local or receptive tourism; they just not shared their knowledge but also they graded the five variable that were picked, based on some attributes that were given previously by the researchers. Finally, at the end of the analysis was found that the most appropriate zone to develop and continue investing on tourism projects is Poblado, because that zone has diversity places of commerce, gastronomy, transportation, hotels and night life.

    Zonas potenciales para generación de energía eólica en la costa caribe colombiana
    (Universidad EIA, 2019) Escobar Aristizábal, Samuel; Ángel Sanint, Enrique
    Con el fin de cumplir los objetivos presentados en el Acuerdo de París, principalmente el de mantener el aumento de la temperatura por debajo de 2 grados centígrados con respecto a los niveles preindustriales y continuar los esfuerzos para limitar el aumento de esta hasta 1.5 grados, los gobiernos que firmaron este acuerdo están migrando hacia tecnologías bajas en carbono. Unas de las tecnologías destacadas , entre estas se encuentra son las fuentes no convencionales de energías renovables (FNCER), un ejemplo de estas es la energía eólica, que además fue considerada como una opción de mitigación de emisión de gases de efecto invernadero por el gobierno colombiano. Como consecuencia de lo anterior, y evaluándolo dentro del marco de energías renovables de Colombia, se realiza una evaluación de la capacidad eólica instalable en la costa caribe colombiana, determinando las zonas viables para la ubicación de granjas eólicas mediante la utilización de un modelo de interpretación ambiental que considera las dimensiones física, biótica, económica, cultural y política. Utilizando un sistema de información georreferenciada (GIS), se generan los mapas que permiten determinar el potencial eólico máximo a instalar.
