LA MULTIFRACTALIDAD COMO HERRAMIENTA PARA SELECCIONAR EL MEJOR ANÁLISIS DE FRECUENCIAS EN UNA DETERMINADA LOCALIDAD

Abstract

The Intensity-Duration-Frequency (IDF) curves can be obtained by analysing extreme rainfall data for a certain place. They are widely used when designing artificial drainage systems or engineering woks that interfere with natural river networks. Extreme rainfall data have to be used to obtain the IDF curves for a certain place. These data have to be statistically analyzed and various method can be applied: local frequency analysis or regional frequency analysis. The objective of the present work is the use of the multifractal properties of rainfall for selecting the most appropriate frequency analysis in order to characterize a widely used IDF model in Spain.
