The study shows the results of the survey and excavation processes conducted in 2019 in Wadi As Sakhin and its vicinities, which is located in the state of Saham. The archaeological evidences found there, reveal richness of the site that indicates occupation that spanned from pre-Islamic to the late and modern Islamic period, with interruption of settlement in some locations during some Islamic periods due to some circumstances .The archaeological survey revealed 23 archaeological sites belonging to different periods, 20 of them inhabited during the Islamic periods. The early Islamic period witnessed a growth in occupation activity, followed by a slight decline in settlement activity during the medium Islamic period, while in the late and recent Islamic period; the evidence indicates significant increase in settlement density. The excavation also revealed four buildings and a copper melting oven, representing a part of the Islamic settlement in Dahwa (DH7), which appear to be the remains of copper mining workshops, which were built with stone foundations and in various ways. The results of the archaeological survey and excavation in this area provided important information on the organization, planning, location and economy of the settlements in the various Islamic periods. The residents' economy of these settlements depended mainly on agricultural production as evidenced by the widespread agricultural fields in some settlements and the diversity of water sources used to irrigate these fields, along with copper mining where copper mining mines and workshops indicate that. There is also an evidence of communication of the residents of Wadi As Sakhin with the residents of the coastal areas, where some shells and fish bones were found in the building layers. Besides, there was also communication with the residents of the interior where local pottery indicates this. On the other hand, the pottery sherds of imported indicates a trade exchange with neighboring regions such as Iraq , Iran, India and China during the various Islamic periods, perhaps through Sohar, by virtue of being the closest central commercial city to Wadi As Sakhin.
