چکیده:

Bahman weir is one of the most famous ancient structures located in Fars province in southwest of Iran. The weir is a masonry rock structure with 7 meters height. The weir dates back to 2000 years ago. It is constructed on GhareAghaj River as a diversion structure to supply Kavar plain irrigation demands. The weir has undergone limited partial repairs several times. The weir has been studied completely in 2002 and its detailed rehabilitation plan has been developed. Site geology, main body geotechnical aspects, weir stabilities against sliding and overturninghave been addressed with especial consideration to its age and historical value. The study also encompasses the weir appurtenance structures including its intake structure and downstream conveyance channel. Investigations show that the ancient Iranian had a deep knowledge on site selection, hydraulic structures, and construction materials.
