Coefficient of variation (in percent) of modeled monthly discharge for the period 1993-2002 for major rivers.

DescriptionCoefficient of Variation of Monthly Discharge

This map shows the coefficient of variation (CV) of monthly modeled discharge for the period 1993-2002 in percent and illustrates seasonal variations in discharge for major rivers.

Interpretation

The Coefficient of Variation (CV) is a statistical measure of the potential seasonal and inter annual fluctuations in river discharge. High variability of discharge is observed in regions where the annual discharge regime is dominated by snow-melt, such as the high latitude regions in river basins draining into the Arctic Ocean, and in regions with a pronounced seasonal rainfall regime.

Background

This dataset is based on a reconstruction of terrestrial discharge for the last century using a macro-scale hydrological model forced with observed global climate data.
