Resumen
En Colombia muchas poblaciones están asentadas en zonas de piedemonte en inmediaciones de ríos torrenciales y expuestas constantemente a inundaciones súbitas. Florencia, ciudad capital del departamento del Caquetá, es una de ellas.Por tanto se vio la necesidad de estudiar esta ciudad que recurrentemente es escenario de inundaciones cobrando casi siempre vidas humanas. Florencia se ubica en el piedemonte de la vertiente oriental de la cordillera Oriental, caracterizada por alta precipitación, producto de procesos convectivos y orográficos. Para el estudio de la amenaza por inundación en la ciudad, se integró la información histórica, hidrometeorológica y geomorfológica, mediante el uso de series hidrológicas e interpretación de geoformas fluviales con imágenes de satélite, fotografías aéreas y validación en campo. Adicionalmente se realizó un estudio regional de la cuenca hidrográfica para determinar la torrencialidad del río Hacha, que bordea la ciudad, y al cual desembocan varias quebradas que también han generado inundaciones súbitas.Esta información es procesada y analizada para realizar cartografía urbana en donde se zonifican áreas de susceptibilidad y amenaza.
In Colombia a lot of populations are located at piedemontes by environs of torrential rivers and constantly exposed to flash floods. Florencia, the capital city of department Caquetá, is one of them. Therefore the necessity to study this city that often has been scene of floods getting human deaths. Florencia is located at piedemonte of the Eastern slope on the Eastern mountain, characterized by high precipitation, made of convective and orographic processes. In order to study hazard flood in the city, historical, hydrometeorological and geomorphological information had to be integrated, using of hidrological series and fluvial interpretation of geophorms by satellite images, aerial photographies and field verificationing. A regional study of the watersheed was made to determine the torrentialiness of the Hacha river, that borders the city, where several drainages fill it and also have generated flash floods.This information is processed and analyzed to make urban cartography where susceptibility and hazard areas are classificated.
