近世・近代における富山藩領の土地利用と治水に関する研究

Abstract

This study is to analyze the history of Toyama town, which had been struggled with repeating damages of floods since it was founded, focusing on its geography, land-use and river management. The resulted findings are as follows. 1) The Joganji-River as well as the Jintsu-River flooded the town. 2) Three major measures taken by the rulers to develop their territory made damages more serious. That is, harnessing the Jintsu-River as a castle moat, expanding the town into the bottomlands along the two rivers and making irrigation systems from the Joganji-River, which also could draw the flood water to the town.
