In order to predict the influence of the water cycle change accompanying a future climate change on the safety of water resources, research in the Fujikawa basin, Nepal Katmandu basin, etc. was conducted aiming at a final purpose of development of the new microbiological-hydrology technique in which hydrology and microbiology were united.As a result, the multi-scale distributed-parameter runoff model used in hydrological analysis and the measurement technique for the pathogenic microbe used in microbiological analysis were developed. Moreover, these techniques were applied to an actual river and groundwater, and we found the relationship between the results of DNA analysis of microbial community structure and isotope analysis, and also found the influence of both rainfall and land use on the behavior of pathogenic microbes.

为了预测伴随未来气候变化的水循环变化对水资源安全的影响，在富士川流域、尼泊尔加德满都流域等地进行了研究，最终目的是开发新的微生物-水文技术，其中水文学和微生物学相结合。建立了用于水文分析的多尺度分布参数径流模型和用于微生物分析的病原微生物测定技术。将这些技术应用于实际的河流和地下水中，发现了微生物群落结构DNA分析结果与同位素分析结果之间的关系，还发现了降雨和土地利用对病原微生物行为的影响。
