Modeling spatio-temporal flow dynamics of groundwater-surface water interactions of the Lake Tana Basin, Upper Blue Nile, Ethiopia

Tibebe B. Tigabu, Paul D. Wagner, Georg Hörmann, Nicola Fohrer
2020 Hydrology Research  
However, combined use of groundwater (GW) and surface water (SW) is still inadequate due to knowledge gaps about the flow dynamics of GW and SW. Mostly, there is no information about groundwater use.  ...  Therefore, this study aims to investigate the dynamics of GW-SW interactions on a spatio-temporal basis in three of the main catchments (Gilgelabay, Gumara and Ribb) that drain into Lake Tana.  ...  Therefore, the application of coupled models to predict multiple outcomes across multiple spatial and temporal scales in the upper Blue Nile basin is recommended.  ...
