Study on the River Conservacy policy to make river channels straight in middle Edo era and Kyuso Muro

Abstract

In this paper, we discuss on the river conservancy policy to make river channels straight in middle Edo era. Firstly, a proposal contained in “KenkaRoku” of Kyuso Muro, a confucianist, is made clear the source of the thought. Secondly, the contents of the proposal is proved to be a misconstruction of the original literatures, Jia Rang's three policies of harnessing the Yellow River, concerning the river conservancy thought of old China.
