Uncertainty analysis of climate change impacts on runoff.

Warming of the atmosphere observed over several decades is associated with the changes occurring in hydrological systems. These changes include precipitation patterns and extremes; the amount and generation of river flow; the frequency and intensity of flood and drought; and, by extension, the quant...
