Abstract Nowadays Egyptian Great Pyramids and Great Sphinx are suffering from rising of Groundwater table. This problem promoted the need to characterize the groundwater occurrences in and around Pyramids Plateau. Multidisciplinary geophysical techniques deployed at the Pyramids Plateau area where, electric resistivity, seismic refraction, and georadar techniques, conducted to delineate the water table. The groundwater table located at elevations of 13 to 17 m asl at the Great Sphinx area, in urbanized area surrounded the Pyramids plateau, located at elevations of 4 to 62 m asl. The groundwater table detected is above the marly limestone which is the formation of the Sphinx, which causes a serious problem of dissolution that cause the monuments fractures. It is recommended to lower the water table by a system of dewatering borehole. Sewage water from the near residence places, nearby Canals, are a sustainable threat for the heritage sites |
