Abstract
A field study was conducted for graduate students, that is, those pursuing master's course, to help them
understand the topographical environment of the 2004 flood inundation of the Maruyama River in northern
Hyogo Prefecture. Furthermore, the topographical environment of the break/overflow points and areas where
internal flooding occurred was assessed. Consequently, through educational practice, the following results
were observed: (1) The number of participants who recognized that the confluence of rivers is related to the
inundation-prone lands along the Maruyama River increased. (2) The number of students who understood the
reasons underlying the land inundation remained unchanged. (3) The number of students who understood
external and internal flooding increased. Our findings indicate that after the class, the students became more
aware of the tributaries of the Maruyama River, and their understanding of the water system deepened.
