Hydrogeological insights in antiquity as indicated by Canaanite and Israelite water systems

Hazor, one of the largest fortified city during the Israelite (Iron-Age) period, encompasses a gigantic underground water system within its perimeter, supplying water to thousands of its inhabitants. It is considered as the ultimate example that Iron-Age engineers had mastered the concept of regional groundwater table. However, evaluating the hydrogeological conditions and the degree of success in finding water in Hazor and other contemporary cities, and thereby assess to what extent this concept was known at that time has seldom been done. Resurveying the water system of Hazor indicates that its water chamber was dug along a major strand of the Dead Sea Fault, a boundary between the Arabian and African (Sinai) plates. Hydrological simulations have shown that water ascends into the water chamber, utilizing this strand. Hazor's engineers initially planned to connect the city with the springs at the foot of the mound (tell) through a shaft and tunnel as has been done at other biblical cities, but adjusted their plan when groundwater was encountered within the mound perimeter. This accidental success as well as the failure to reach the aquifer in deep water wells dug in the contemporary cities of Lachish and Beer Sheba, imply limited hydrogeological understanding at the beginning of the first millennium B.C.E.     

The Iron Age Maritime Interface at the South Bay of Tel Dor: results from the 2016 and 2017 excavation seasons

The aim of the Tel Dor joint Sea and Land Project is to reassess and expand understanding of the maritime interface of Iron Age Dor. During 2016 and 2017 five features excavated under water provided new data about the development and chronology of this interface. The results support a revised dating and interpretation of previously excavated structures and the identification of several new stone‐built coastal fortification and maritime features, dating to the Early Iron Age. A later phase of construction attributed to the 7th century BCE Assyrian period at Dor was also documented. The outcome of the excavation is the introduction of new aspects of the development of Dor in the Iron Age, including what is likely part of the Iron Age II city's harbour. This may encourage revisiting current views of harbour evolution in the eastern Mediterranean.
