We discussed influence of landslip landforms on rivers in Maetsue area, Hita city, Ooita prefecture. ln this study area, there are 195 landslip landforms, and they were classified into four types by their landforms interpreted by aerial photographs. We considered that existence of cap rock is to be a geologic factor of developing larger landslip landforms in this area.<BR>We investigated relationships between landforms of river and landslip landforms by using stream profile and profile of channel slope. Where larger landslip lobes close to the river, some sections of the stream profile and the profile of channel slope become convex curve caused by aggradations of elevation of river bed. By the form of convex lines on the profile of channel slope, the profile can present more and clearer sections affected by landslip landforms than the stream profile.<BR>Consequently, we consider that we can estimate easily the affected areas by landslip landforms on investigation of such sections of the stream profile. Furthermore, we can indicate the area more clearly from the drawing of the profile of channel slope.<BR>It is easy for us to present the landforms of the river by using GIS software and detailed geographic information.
