LUNA VERA, José Antonio  e  DOMINGUEZ MORA, Ramón. A method for regional frequency analysis of maximum daily rainfall: application in the Bolivian Andes. Ingeniare. Rev. chil. ing. [online]. 2013, vol.21, n.1, pp.111-124. ISSN 0718-3305.  http://dx.doi.org/10.4067/S0718-33052013000100010.

A regional frequency analysis of daily annual maximum rainfall series for an area with poor information is presented. The complex topography mountains and the highlands region in the Cordillera de Los Andes, Bolivia, produce different patterns of daily rainfall. The combination of L-Moments and cluster analysis are adequate to identify the homogeneous regions of the annual maximum series. The work defines 4 homogeneous regions. Region 1 includes the stations located in the highlands and south-east. Region 2 covers the central highlands and La Paz River Basin, consisting of inter-Andean basins. Region 3 clearly defines the Amazonian basin stations and 4 is composed of stations located in the northern mountains. Different distributions were tested for regional frequency analysis using the Index Flood method, the best results were obtained with the Double Gumbel and Gumbel functions. Finally, regional equations are compared with some specified series of each region, in order to verify the applicability of the proposed methodology for hydrological design purposes.

Palavras-chave : Regionalization; maximum daily rainfall; L-moments; index-flood method; k-means method; homogenization; frequency analysis.
