建部井堰 ― 現存する日本最大の農業用の総石張取水堰 ―

 Takebe-Iseki weir is the largest existing stone-built diversion weir in the Edo era, but it's existence is almost unknown even among the specialists of historical river engineering. Once this weir was preserved as the tangible cultural structure of Takebe Town, but it was dissolved when Takebe Town was acquired by Okayama City. This paper try to evaluate the importance of the weir using historiographical materials, comparative analysis and detailed surveying, which anticipates possible re-designation of the weir to the important cultural property.
