Análisis de confiabilidad de metodologías para la estimación de curvas sintéticas regionalizadas de intensidad, duración y frecuencia, para el Departamento de Boyacá Colombia

Abstract

The Intensity-Duration-Frequency (IDF) curves allow estimating volumes surface drainage through rainfall-runoff models in small watersheds for which there are no records of flow. Traditional methods of calculation of IDF curves pluviographic require the use of information. The use of equations that allow estimate IDF curves from rainfall information is an alternative for areas that only have rainfall records on a daily basis. Through this research is to evaluate and analyze mathematical models regionalization in the literature of hydrology for Colombia, using data of maximum precipitation for different durations of time, as well as IDF curves equations resulting from the study of twenty stations hydrometeorological IDEAM, which are contained in a total of ten grade students work group of hydrological research Ūdens District University. Complementarily were available multiyear the rainfall records same to determine the parameters of the equations of intensity and duration frequency characteristics of each season, which will be obtained through bank IDEAM data. This document also contains a comparative analysis of the results obtained from the application of synthetic curves using the constants regionalized the study developed by Engineer Mario Diaz-Granados, versus equations found using pluviographic and rainfall information and equations obtained at different grade papers for each of the stations studied. The results obtained in this research exercise verify allow applicability and reliability of the methodology proposed by Engineer Mario Diazgranados, demonstrating that the hydrological behavior of a catchment depends not only its location, but other factors such as the average maximum annual value of daily precipitation, number of days with rain per year, annual rainfall, and elevation above sea level.
