Simulación de crecidas : influencia de los métodos de cálculo de hidrogramas en la incertidumbre de las crecidas simuladas: caso de estudio de la quebrada Guanga Huaycu, sector la Gasca.

Abstract

The purpose of this work is to carry out a study of the precipitations of four meteorological stations near the Guanga Huaycu basin, to consider the use of these within the ungauged basin, to estimate a precipitation scenario using maximum station values. With the same value of accumulated daily precipitation and simulate in the HEC-HMS software several methods for losses, transformation, and base flow, for this the physical geographical characteristics of the study basin, its texture and use of the soil in based on information obtained from the National Information System. Also, through a comparative analysis of the hydrograph calculation methods available in the HEC-HMS software, it seeks to obtain a simulation with data close to the flood that occurred on January 31, 2022, where the peak flows are obtained to calculate later. the specific flows and make a comparative analysis with small basins and close to the place of study. Said analysis revealed a great variety of results and the imminent need to have observed flow data for the calibration and selection of a specific model.
