Looking for a Solution: Unipillar Bridging at Chah Hossaini

Iranian Baluchestan, especially the Bampur Valley, in which Chah Hossaini is located close to the Jaz Murian Depresion, has had a long history of floods and droughts. The environmental setting of the region is significant from two perspectives, trans-regional and regional. From the trans-regional perspective, the region is situated in atransitional climate area, located between tropical and subtropical areas. Therefore, it has been faced with periodical changes, including droughts and floods. From the regional perspective, a striking feature in much of western and central Asia is the number of enclosed basins that have no drainage outlet to the sea. More than half the IranianPlateau is covered by enclosed basins, of which the Jaz Murian is one. Floods and wind sediments in the area where Chah Hosseini is located result from the most characteristic environmental disasters that are related to droughts and floods. During the first season of excavation, Sept.-Oct. 2019, evidence of flooding and wind sediments were reportedfrom 18 small tranches, each with an average depth of 4-metres. A research goal is to identify conclusive evidence of Neolithic and Chalcolithic remains at the site, in order to solve the problem of the gap between Chah Hosseini and previous periods in Paleolithic sites. To advance our knowledge of these issues in the next season of excavation,sedimentological techniques will be applied to understand and date environmental changes in the stratigraphic layers.
