Abstract:
This project is mainly intended to study the hydrologic impascts of changing climate in the most complex and dynamic Nile river flow for the next 100 years. 11 GCMs with the most recent climate predictions that have contributed to the IPCC 4th ( AR4 ) with two emission scenarios ( A2 and B1)and some of the GCMS having single runs and some with multiple runs are used. The highly course met data from GCMs went through further bias correcton and spatial dawnscaling to correct for the inhrent bias level and avaoid the scale mismatch with hydrologic models currently in use. We force our Macro scale land surface hydrologic model at 1/2 degree spatial scale to predcit future Nile river flow taking in to consideration lakes, wetlands, reservior and Nile suds hydrodaynamics.
