|Abstract: ||The Nile River receives its water primarily from Lake Victorias catchment basin, and is a
particularly vital source of potable water in that region. Since greenhouse gases induce climate
change that will affect the water resources system, this necessitates a fundamental review of both the
planning and management of water resources. This study delivers the range of plausible changes in
flows of five rivers (tributaries) to Lake Victoria from the year 2010 to 2099. Two different
hydrological conceptual models, namely IHACRES and SMAR, are used in establishing the daily
rainfall-runoff relationships for the five sub-catchments (tributaries) within the Lake Victoria basin.
The five catchment sites are Nzoia, Yala, Sondu, Gucha and Mara.
A number of climate change scenarios from several General Circulation Models (GCMs),
taking into account different CO2 emission forcings have been successfully used by these
hydrological models in order to simulate the corresponding future river flows in the five subcatchments.
The results suggest an increase in mean annual flow in the 2020s period. However, the
river flow trends in the 2050s and 2080s are inconclusive. The results show the potential for climate
change to modify river flows, thus requiring a significant planning response. The results, amongst
others also indicate the importance of considering hydrological impacts in potable water supply and
