Estudio de la respuesta hidrológica de dos cuencas hidrográficas en el Litoral Central, Cordillera de la Costa, Venezuela

The Petaquire-Mamo and La Zorra basins are two systems frequently affected by hydrometeorological phenomena invading the Litoral Central [Central Coastal Area, in English] of Venezuela, measuring its vulnerability by the number of population and infrastructure committed every time they overflow. This study aims to analyze the hydrological response of these systems by designing computer models using HEC-HMS (v 4.4.1) program. Three weather stations were selected to represent the study area, besides probability distributions of extreme values type I (EVI) Gumbel were designed, which together with the Intensity-Duration-Frequency (IDF) and Depth-Duration-Frequency (DDF) curves allowed the calibration of 6-hour and 24-hour storms, as well as return periods of 2, 25, 50
