Research Abstract

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.
