ArcSWAT-based modeling of climate-driven changes in discharge and groundwater recharge in Nigeria’s Benue basin

Key Points

• Discharge and groundwater recharge are projected to change significantly due to climate variations.
• A projected 15% increase in discharge is noted during the wet season in future climate scenarios, reflecting hydrological shifts.
• ArcSWAT modeling was employed to simulate the impacts of climate change on hydrology within the Benue Basin region.
• Highlights the need for improved water management strategies in response to projected hydrological changes.
