A STUDY OF THE WATER BALANCE IN TREE SELECTED SUB-BASINS OF THE CENTRAL RIFT VALLEY, ETHIOPIA INFLUENCED BY CLIMATIC CHANGE

Popis výsledku v původním jazyce

This study investigated the impacts of future climate change on the major components of the water balance in the Central Rift Valley Basin in Ethiopia from the seasonal and the spatial point of views. The evaluations are based on the magnitude of water yield, evapotranspiration and surface runoff components changed in relation to the baseline data outputs. Regional Climate Models (RCM) data in CORDEX - Africa were applied for the investigation. RCP data from the MIROC-RCA4 ensemble driving climate models were downscaled, bias corrected and used for the analyses. The methodology followed a calibrated Arc-SWAT modelling approaches to search for basin wide climate impacts on water resources and to indicate possible agricultural water management and adaptation strategies. The findings are solely based on model simulation outputs within the scope of its evaluations and error limitations. The study also indicated huge impacts of regional climate forcings (RCM) on surface components of the regional water cycle. These RCMs are a derivative of the Global Circulation Models (GCM). The management interventions to the climate impacts should therefore be according to the sub-basins water balance sensitivities while keeping the equilibrium in the closed CRVB water requirements. Finally, an investigated integrated watershed, agricultural water use, and farm management in Water-Agriculture-Land and Climate nexus approaches following each sub-basin climate responses and other alternative resource management options for the closed CRVB must be fetched and applied to cope up with the hydroclimatic impacts.
