Water resources management including mitigation of floods and droughts as well as related ediment disasters under changing environments is one of key factors for sustainable rural development. Safe and secure water supply is "essential" for promoting sustainable resource management and conservations. Much more comprehensive approaches for water resources management is required in various scales from regional to watersheds in Europe, Asia, Africa, and America. Detail information for understanding hydrological and geomorphic processes is necessary for not only progress of sciences but also developing simulation model for future prediction. This research team aims to develop a sustainable green infrastructure through appropriate forest and agricultural land management. We focus on establishment of indicators of volume and quality of water and sediment dynamics. This study is consisted by (1) evaluating of hydrological and geomorphic processes water for appropriate management in watershed, and (2) establishing an international platform of green infrastructure of watershed and integrated resources management.


it is necessary for water to implement sustainable "water supply" and to mitigate disasters by excessive water in terms of regional disaster prevention for maintain the local community and sustainable agriculture. Because of changes in magnitude and frequency of extreme weather events, both local and global viewpoints for hydrological and geomorphic processes in multiple land use such as forest and agriculture lands. In water resources management and regional disaster prevention, we integrate knowledge in various fields including "agricultural engineering", "forestry science", and "erosion control engineering". Then, we further develop numerical simulation for predict future scenarios and analysis.
In this study, we particularly focused on clarifying various functions such as soil conservation from agricultural and forest lands with environmental and social changes (i.e. population). Establishing appropriate methods and applications of green infrastructure for maximizing and optimizing the natural functions. We will integrate existing and new data in watersheds of various locations around the worlds such as Japan, Asia, and North America. Then, we develop model for simulation and prediction of runoff and sediment transport by changing land use and management practices for regional resources assessment. In this study, we also compare watersheds in various land use, climate, vegetation and geology types for comprehending processes and models.


We combine new and existing data for effective researches and numerical simulations. In 2018, we will obtain further field information which is necessary for process understandings and model development. For the core sites of this study, Gomi will continuously work in FM Karasawayama in which data had also been accumulated by JST/CREST project. Toda, Shiraki and Gomi will focus on watersheds in Kanagawa Prefecture management by Nature Conservation Center. Kato will focus on Inbanuma basin. Furthermore, Saito and Gomi will work on landslides and slope stability in areas affected by Kumamoto earthquake. In addition to such field investigation, we also utilize long-term observation data from the United States and Canada as inter-site comparison study. Collaborative research with Kasetsart University, Gajah Mada University and Vietnam Forestry University will be continued by all member.
Our project will advance a research by the two wheels of field observation and modeling for green infrastructure. Professor Sidle who is specialized in field-based watershed hydrogeomorphology and analysis on comprehensive sustainability in the context of green infrastructure. Together with Dr. Lee MacDonald, we will focus on from the viewpoint of sediment-related disasters and regional disaster prevention measures, water resources, water quality, ecosystem, soil and slope in watershed scales.
