Estudio de precipitaciones en la ciudad de Trelew, análisis estadístico y ecuación de lluvia

Abstract

This paper aims to organize and systematize rainfall data for the Trelew catchment area, and update the rain equations for the series of data available to date. Statistical studies of storms, which determine the relations of intensity-duration-frequency (I-d-F curves), form the basis of calculation for determining storm design in innumerable problems of hydraulic engineering and related sciences. Dynamic variables should be subject to continuous analysis and permanent adjustment, especially in the most sensitive variables, such as maximum rainfall, hence new functional relationships can be found, which prove to be different to those existing, in terms of the associated return periods. The interpretation and use must be made strictly within the framework of the assumptions of the probabilistic method with its limitations and restrictions. The new, adjusted functional relationships are those recommended to be used in determining the rainfall event or events that form the base of technical study and the design of works. The systematized information attempts to achieve a dissemination mechanism that contributes to the knowledge of potential users and can be used by the different sectors with interests in the field.
