Abstract

This paper shows the results obtained when five methods for imputing missing daily rainfall were applied to records of eight hydrological stations located in the Quindío river basin, on the west-center part of Colombia. With the purpose of preserving the presence of no rainfall data, were considered calculate the empirical probabilities of first-order Markov chains. The five methods were implemented with a recursive algorithm which initializes missing data with the average daily rainfall. After this, the algorithm runs iteratively, replacing the previous run missing data imputations, it runs until the maximum difference between two successive imputations is smaller than a threshold value. Data imputed by the Statistical Measure Weighting Method conserves the measures of central tendency from each station daily rainfall record when it includes missing data.
