The effects of more frequent heavy rainfall and more severe Japanese serow attacks have been observed in some areas, indicating an increased risk of slope failure. These factors are expected to increase due to climate change, and combined slope failures are likely to occur more frequently in various regions of Japan. In order to cope with these factors, it is necessary to establish methods for early prediction and forecasting, and to develop efficient countermeasures. On the other hand, in order to predict and forecast, it is necessary to clarify the characteristics of soil infiltration capacity that changes due to erosion, and to model what kind of infiltration process occurs on the slope. To develop the model, we compared the infiltration capacity of rainwater and runoff chemical composition between the deer- and non-deer-infested areas. Based on this comparative analysis, the effects of surface soil changes due to feeding damage were determined.
