Luisa Fernanda Yustres Quintero,

Colombia es uno de los países que se caracteriza por una alta variabilidad espacio – temporal de los parámetros hidroclimatológicos definida por un abanico de diferentes fenómenos macro climáticos. Uno de estos es el fenómeno de la Oscilación Cuasi-Bienal que ha sido poco estudiado en el contexto nacional. En el estudio se llegó a obtener la incidencia de este fenómeno sobre el régimen hídrico de los afluentes del embalse Betania los cuales son importante desde el punto de vista de la producción de hidroenergía y las actividades agropecuarias de la zona. Durante la investigación se encontró que el evento macro climático logra manifestarse en un periodo de 4 a 7 meses y su aporte a la variabilidad interanual de caudales es hasta el 13.7 %, teniendo en cuenta que las intervenciones antrópicas en la zona afectan los niveles de los caudales donde se ven reflejados los resultados al obtener las correlaciones.


Deforestation is a process that has increased in different areas of the world that is directly related to human activities, this is one of the factors that affect the regulation of water basins. The objective is to develop a methodology to make an evaluation. This is an index of the water regulation, the frequency, the information about the hydrographic basin that contains the PPN orchids. Contrasting the evaluation of water regulation and the multitemporal study of coverage following the Corine Land methodology Coverage adapted for Colombia up to a third level evaluating ten coverages. The change of social networks is identified
