Unbiased Estimate of Statistical Entropy of Hydrological Series

S. K. Davletgaliev

Studied is the dependence of the entropy on the series of annual runoff on the number of observation years. Plotted are nomograms for estimating the unbiased value of the entropy depending on the number of observation years and number of gradations. Nomograms are plotted from the simulated series for the Pearson type III distribution.
