RAYNAL, José A.. FLODRO 4.0: A personal computer model for flood frequency analysis. Tecnol. cienc. agua [online]. 2012, vol.3, n.2, pp.41-50. ISSN 2007-2422.

A computer package is presented for flood frequency analysis based on the application of commonly used Excel® spreadsheets (Excel is a registered trademark of Microsoft Corporation, Inc.), using several probability distribution functions. The computer package handles the estimation of parameters, design values and confidence limits for several return periods using several methods to determine these estimations. The computer model uses up to three goodness of fit tests and is able to produce several graphic displays that aid visual comparisons among competing models. The paper includes an application example using the generalized extreme value probability distribution function and probability weighted moments for the method of estimation, to show the ease of using this computer package.

Palavras-chave : flood frequency analysis; spreadsheets; probability distribution functions; estimation of parameters; estimation of design values; confidence limits.
