Abstract
Description
Este trabajo presenta una modelación hidrológica con HEC-HMS de una pequeña cuenca experimental urbana, ubicada en zona montañosa de la ciudad de Manizales, Colombia. El estudio se realiza para conocer la respuesta hidrológica en cuencas urbanas de alta montaña, donde el aumento del proceso de urbanización ha producido modificaciones en la dinámica natural de las cuencas, trayendo como consecuencia aumentos en los volúmenes de escorrentía, en los caudales punta y en las velocidades de flujo, lo que a su vez incrementa el riesgo a inundaciones pluviales. Esta problemática es más crítica en cuencas urbanas de montaña ya que las altas pendientes aumentan aún más las velocidades de flujo. En este tipo de cuencas se tienen pocos estudios. Del análisis realizado en la cuenca seleccionada se encuentra que el uso de suelo ejerce mayor control de las altas pendientes en la respuesta hidrológica.
Here is presented a HEC-HMS hydrological modeling in a small experimental urban watershed, located in a mountainous area of the city of Manizales, Colombia. The study is realized to determine hydrological response in high mountain urban watersheds, where urbanization has created an acute problem relating to floods. This process has produced changes in natural dynamics of watersheds, resulting increases in runoff volumes, peak flows and flow velocities, what in turn increases the floods risk. This problem is most critical in urban mountain watersheds, due to steep slopes, it rises even more flow velocities. From the analysis in the selected watershed, it was found that land use exerts greater control over the hydrological response than high slopes.
