Micro-hydropower considered to have a small environmental load, but since a water abstraction reach exists, it is necessary to evaluate the impact on the river ecosystem correctly. In this study, the influence of water abstraction by micro hydropower was quantitatively evaluated for each habitat type of mountain streams using benthos as a sensitive index. As a result of field investigation, in the Kaji River, the influence on the benthic animal population, the number of taxonomic groups, and the community structure by water abstraction were not statistically recognised in all mountain stream habitats. In the Kamo River, the number of benthic animals and the number of taxonomic groups decreased in the water abstraction reach in some habitats, including step, cascade, rapid and stagnation.

In this study, we attempted to develop information that can be used as an adaptation measure to prepare spatio-temporal sediment disaster prone areas risk information according to maximum heavy rainfall from the past to the future forecast. The target area is Nagano Prefecture. The risk information of the warning area was derived using the probable maximum precipitation as the maximum rainfall. In addition, we have developed probability risk map from the past to the future of the caution zone obtained by using slope failure probability model as spatio-temporal sediment disaster prone areas risk information. As a re-sult, The sediment disaster prone areas risk information has been developed in each climate condition (present, near furture and future), and the quantification of risks has been attempted the time change according to local area. Information on local governments was obtained to need to support of counter measure. In addition, resulting output data was suggested to use a case study of adaptation measures.
