Abstract
Significance of the integrated watershed management was quantified considering individuals' daily activity-travel patterns in Lake Biwa and the Yodo River basin. Time taken to move in the basin by car and railway was calculated using geographic information system (GIS) to establish a “person trip model”. The condition of person trip to attend office and school was estimated and its variation tendency in the future was evaluated. The results show that the interchange region in Lake Biwa and the Yodo River basin has been expanded and the basin has been united.
