The hydrological environment must be understood before water flow can be adequately controlled to prevent slope failure without impacting unduly on the hydrological mountain slope environment. We conducted field studies to determine current sites and measurement of ground temperature 1 meter deep to clarify groundwater flow passageways on the slope behind the cultural heritage temple Kiyomizudera in Kyoto. Results showed anomalous temperature 1 meter deep bands on the slope and several springs that are extensions of these bands. Several of these bands coincide with terrain deformations such as gullies and slope failure scars indicating the probability of relationships between groundwater flow and topological deformation.
