Monitoring temporal variations in groundwater levels provides a key to sustainable freshwater resource utilization and management, sustainable land use, and sustainable crop acreage, yield, and production. This study used ground penetrating radar (GPR) to monitor temporal variations in groundwater levels in urban areas, and to define the factors that control these variations. The city of Ismailia, Egypt, was selected as a test site because it is experiencing a rise in groundwater levels that poses potential environmental risks, and it lacks the groundwater wells necessary for monitoring and mitigation.

Groundwater samples from deep Nubian aquifer wells (total depths 747 to 1250m) have Ra and Ra activities ranging from 0.168 to 0.
