The formative processes of archaeological sites are connected with the effects of topographical environment. In this regard, this paper deals with the result of the excavations in the Yoshida campus of Kyoto University, situated in the north-eastern part of the City of Kyoto. In the area these effects are mainly recorded on the change of sediment formation which consists of sand beds and covers a marginal part of the Kitashirakawa alluvial fan. It should be pointed out that the formation date of the Yellow Sand Bed, the key bed of the area, is confirmed to be the early Middle phase of the Yayoi period judging from the artefacts and from the fact that the Bed was worn out after the formation by the old Takano River, having made a step at the east of the Higashi-Oji Avenue. The step was readjusted with a different level about 2.5m high from the west side, as we see it now, at the Edo period. It is seen that the water-courses have changed topographical environments and man has made the best use of these kinds of changes from the prehistoric age to the present.
