 note = {This is the fourth of a series of papers on the Ura River basin (AOKI et al 1981, 1982 and 1983) and deals with the results of the research carried out in 1983. The results can be summarized as follows: 1. In order to analyze the possibility of landslide, a boring test with 80m depth was carried out in the hazardous slope as shown in Fig. 1.  2. In the area of the lower stream of the Ura river, we found the distribution of pyroclastic flow derived from the Kazabuki volcano. 3. From July to October in 1983, we observed 21 debris flows in the Kanayama river by using T.V. cameras (Table 2). Observation data are shown in Table 3 and Table 4. The results of soil tests for debris flow deposit are shown in Tables 5 to 8 and Fig. 3. 4. From the multivariate analysis on the relationships between the rainfall and the occurrence of debris flows, the results suggest that the occurrence of debris flows was related to not only the rainfall but also to other factors (Fig. 9 and Table 12). 5. A change in the electrical conductivity of river water by recorder suggests the occurrence of flowing water with high electrical conductivity before the occurrence of debris flow as shown in Fig. 11.},
