| description | Colombia is one of the countries whose hydrological regime is highly influenced by different macro-climatic phenomena. It has been shown that the ENSO phenomenon in some regions of the country affects surface runoff by 30%, which has a direct impact on socio-economic activities. There are other phenomena whose incidence on hydrological variability has not been studied in depth. One of these is the event of the Quasi Biennial Oscillation (QBO). The study analyzed the influence of this phenomenon on the influx of the south Bogota system that supplies drinking water to 250,000 people living in the town of Usme. Using a series of monthly average results of stations located upstream of the reservoirs studied and of the historical OCB index at 50 hPa, a methodology based on correlative analysis between the monthly inflows to the reservoirs and the macro-climatic index that characterizes the OCB phenomenon. It was shown that this phenomenon manifests itself with a delay of 11 to 12 months and that the water regime in 10 to 14% depends on the phenomenon of OCB. This demonstrates that hydrological variability depends not only on the ENSO phenomenon but also on the OCB, but to a lesser degree, and must be taken into account in studies of hydrological variability and its incidence on the development of productive activities dependent of water. |

Colombia es uno de los países cuyo régimen hidrológico se encuentra altamente influenciado por diferentes fenómenos macro climáticos. Se ha demostrado que el fenómeno ENSO en algunas regiones del país afecta en un 30% la escorrentía superficial, esto repercute directamente en las actividades de los sectores sociales, económicos y en las condiciones ambientales de estas zonas. Existen otros fenómenos cuya incidencia sobre la variabilidad hidrológica no se ha estudiado a profundidad, uno de estos es el evento de la Oscilación Cuasi Bienal (OCB). En este estudio se examinó la influencia de este fenómeno sobre las afluencias del sistema de abastecimiento hídrico sur de Bogotá, conformado por los embalses Chisacá y la Regadera, cuya importancia radica en permitir el abastecimiento de agua potable para los habitantes de localidad de Usme, en la cual residen 250.000 personas aproximadamente. Haciendo uso de series de caudales promedios mensuales de estaciones ubicadas aguas arriba de los embalses estudiados y del índice histórico de OCB a 50 hPa, se diseñó una metodología basada en el análisis correlativo entre las afluencias mensuales a los embalses y el índice macro climático que caracteriza el fenómeno OCB, y se demostró que este fenómeno se manifiesta con un retardo de 11 a 12 meses en la zona de estudio y que el régimen hídrico en un 10 a 14 % depende de la aparición de este evento climático. Los resultados obtenidos demuestran que la variabilidad hidrológica en la zona del estudio no solo depende del fenómeno del ENSO sino también de la OCB, aunque un menor grado, y debe ser tenida en cuenta en los estudios de la variabilidad hidrológica y modelos predictivos de los fenómenos macroclimáticos debido a su relevancia sobre las actividades productivas dependientes del agua.
