Determinación de zonas urbanas vulnerables a inundaciones causadas por las principales quebradas de Guano empleando distintos modelos hidrológicos e hidráulicos

Nowadays there are some mechanisms that allow obtaining information related to the effects caused by floods in urban areas, to achieve this, it is necessary to carry out hydrological studies through which flood flows are obtained using rainfall-runoff models, with this study it is possible to execute the respective hydraulic modeling, that show the flood zones with their respective depths and speeds, thus allowing the establishment of possible irrigation zones. Based on this study, maps of urban areas vulnerable to flooding caused by the “San Sebastián” and “El Rosario” streams were obtained that run through the urban part of the Guano canton, for which it was necessary to obtain physiographic, geomorphological and drainage system parameters of each of the basins under study, first, a hydrological modeling was carried out using the HEC-HMS program this parameter was the main one for the determination of the maximum flood flows using the Curve Number. Afterwards, the 1D and 2D hydraulic modeling was carried out respectively, using the HEC-RAS program, which shows flood maps with the date of greatest precipitation corresponding to March 2, 2021 and with a return period of 50 years. With the results of the study obtained, it was concluded that the flood map with a return period of 50 years is much broader causing greater damage than the one registered on March 2, 2021, besides presenting higher heights and flood speeds, which would cause great losses and damages of great magnitude
