Hydrological Models and Climate Change

Author:
[ Nasseri ] -

Abstract:

Global circulation models (GCMs) which simulate the earth climate show that temperature will increase by about 1-3.5' c globally by 2100. Hydrological impacts include chznges in the storage of water in soils, aquifers and lakes, and changes in the amount and annual distribution of river discharge. The impact of climate variability on streamflow and water balance components was simulated in two hydrologically and geologically different basins using two deterministic rainfall - runoff models SAC-SMA and BROOK90. The statistical results of SAC-SMA model suggest that the precipitation changes of more than 10% would be necessary to the significant changes of runoff from the historical stream flow series, The results of models illustrate that under higher temperature conditions more precipitation results from rain rather than as snow, and snow melt runoff occurs earlier in the year.
