Abstract

This paper explores possible linear relationships between annual instantanous peak discharge (IPF) and the corresponding (MDF) mean daily stream flow. The use of Principal Component Analysis (PCA) allowed characterizing the most important topographic and hydrological attributes of the basins and provided important information about variables that should be included in IPF-MDF regional equations. The key factor to justify the different IPF-MDF relationships in a relatively small area is the nature of the extreme events and their effects on semi-arid soil conditions. In addition, a regional equation to estimate IPF from MDF was developed. This equation was applied to a series of flow of 9 stations of the Southeast Basin of Spain, and a significant improvement was achieved when applying this formula in comparison to the traditional method of Fuller. This study indicates possible restrictions to take into account when traditional hydrological model are applied in semi-arid areas
