DUQUE-SARANGO, Paola; PATINO, Daysi M.  e  LOPEZ, Xavier E.. Evaluation of the Hydrological Modeling System HEC-HMS for the Hydrological Simulation of a Tropical Andean Micro-basin. Inf. tecnol. [online]. 2019, vol.30, n.6, pp.351-362. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642019000600351.

The present study simulated the hydrological behavior in a tropical catchment in the Andes of Ecuador, known as the Chaquilcay micro basin, situated in the province of Azuay, in Ecuador. Hydrographs to determine flows are obtained and for generating hydrological information about micro basins, especially in zones where this type of studies do not exist. Intensity, duration-frequency curves (IDF) were used for the construction of hietograms. With this information, a hydrological modeling system was applied, with the HEC-HMS tool (version 4.1), and the ArcMap 10.1 program to determine the morphological characteristics of the basin. It was possible to obtain a peak flow in the drainage of 1.7 m3 /s, 1.8 m3 /s 1.9 m3 /s for return periods of 25, 50 and 100 years respectively. This investigation can be useful for hydrographic basins in the area of the Ecuadorian region, which have an important function in the ecosystem but do not have hydro meteorological information.
