A runoff map based on numerically simulated precipitation and a projection of future runoff in Iceland

Jonsdottir, Jona Finndis LU (2008) In Hydrological Sciences Journal 53(1). p.100-111
Abstract
The runoff of Iceland has been evaluated for the period 1961-1990, and changes in runoff from then to the period 2071-2100 predicted according to a future projection of climate change. The hydrological model WASIM-ETH was used, with meteorological data from the PSU/NCAR MM5 numerical weather model. The evaluation of the effects of climate change on water resources was based on a future climate simulation from the HIRHAM regional climate model with boundary conditions from the HadAM3H global climate model using A2 and B2 emissions scenarios. Future runoff was shown to become much higher in 2071-2100 compared to 1961-1990, predominantly due to increased glacial melt caused by increased temperature. Furthermore, changes in runoff seasonality... (More)

Future runoff was shown to become much higher in 2071-2100 compared to 1961-1990, predominantly due to increased glacial melt caused by increased temperature. Furthermore, changes in runoff seasonality would be substantial. Thus, according to this projection there could be great changes in hydropower production potential associated with climate change in Iceland. (Less)
