Abstract
Previous seasons of excavation at the site of Humayma in southern Jordan have revealed an<br>important Roman fort, dating from the early 2nd century to the late 4th century AD, which is the earliest<br>known Roman fort in Jordan. Several other settlement areas were found at the site covering an<br>occupation span of almost 900 years. Three geophysical tools -- ground-penetrating radar, electrical<br>resistivity, and magnetic gradiometry -- were used to conduct a geophysical survey of the Roman fort, in<br>order to verify the layout of the many well preserved interior and exterior structures. The survey<br>focused mainly on the areas inside and immediately surrounding the exterior walls of the fort. The 200<br>m by 150 m structure was surveyed inside using eleven small sized zones with a 1 m profile spacing and<br>outside using five larger sized zones with a 2.5 m profile spacing. The survey has revealed several<br>internal structures of the fort, as well as some major features outside the fort, such as a possible semicircular<br>defense structure and sections of the site’s water supply system.
