Abstract:

Groundwater is a critical resource for many regions, particularly in Africa where it serves as a primary source of drinking water and irrigation. Effective groundwater exploration and monitoring require accurate data on subsurface conditions. This article explores the integration of geophysical and hydrological data to enhance groundwater exploration and monitoring. By combining methods such as electrical resistivity tomography (ERT), ground-penetrating radar (GPR), and time-domain electromagnetic (TDEM) surveys with hydrological data, more precise models of groundwater systems can be developed. The paper reviews recent advancements in geophysical techniques and their application in various case studies, including Kenya’s use of ERT for mapping aquifer systems and South Africa’s integration of GPR and hydrological data for managing groundwater resources. The integration approach provides a comprehensive understanding of subsurface conditions, improves groundwater resource management, and enhances predictive capabilities. This article also discusses the challenges associated with data integration and provides recommendations for future research and practice. By presenting a synthesis of current methodologies and practical examples, the study offers valuable insights for researchers, practitioners, and policymakers involved in groundwater management.
