矢作川流域の中山間地域を対象とした流出解析

Abstract

In the hilly and mountainous area of the Yahagi River basin, which includes forests, rice paddies (including abandoned rice paddies), and small rivers, runoff analysis was conducted using the SWMM (Storm Water Management Model). By setting the SWMM parameters based on the results of previous studies, we were able to almost reproduce the observed values at the Takabashi Water Level Observation Station. Predictions were made for further runoff reduction measures for forests, rice paddies, and small rivers, and specific examples of measures in three areas of Toyota City were presented.
