El propósito de este trabajo es calibrar un modelo para la estimación de caudales máximos que se adapte a las características hidrológicas, geomorfológicas y de cobertura vegetal de las cuencas colombianas. Por esta razón, se calibraron los parámetros del modelo probabilístico MG para todo el territorio colombiano, sus principales regiones geográficas y subregiones hidrológicamente homogéneas. Para la obtención de las ecuaciones analíticas del modelo MG se utilizaron los registros históricos de caudales máximos de 277 estaciones limnigráficas distribuidas a lo largo del territorio colombiano. Los resultados obtenidos aplicando el modelo MG calibrado y otros métodos comúnmente utilizados con el mismo propósito fueron comparados entre sí y se encontraron valores muy semejantes. El modelo MG calibrado en este trabajo se muestra como una opción viable para la estimación de caudales máximos en cuencas con información escasa en Colombia.
Abstract: The purpose of this paper is calibrate a model for estimating peak flows adapted to the hydrological, geomorphological, and vegetation cover in Colombian basins. For this reason, the parameters of probabilistic MG model were calibrated for the whole territory of Colombia, its major geographic regions and hydrologically homogeneous subregions. To obtain the analytical equations of the MG model, historical records of peak flowsin 277 water level recorder stations in Colombian were used. The obtained results by applying the MG calibrated model and other commonly used methods to estimate peak flows were compared, and very similar values were found. The MG model calibrated in this work is shown as a viable option for estimating peak flows in basins with scarce data in Colombia.
