 The study examined the potential impact of climate change on the hydrology of the Nianto River and Lake Tana catchments in Ethiopia. It found that climate change could lead to increased mean river flow and extreme peak flows in the Nianto catchment, but not in the Lake Tana catchment. Additionally, the hydrological models used in the study had difficulty accurately predicting extreme flows in the Lake Tana catchment, suggesting that further research should be done to verify their accuracy.
