Outline and Purpose of the Course A method to model the mechanisms of natural and social phenomena related to water resources as a system will be introduced, and lectures will be given on planning theory and management theory for the sustainable use of water resources. Specifically, first, after explaining the idea of systematically thinking about water resource-related problems, lectures will be given on the theory and methodology of the mathematical planning approach to water resource planning/management, as well as the water resource dynamics modeling relationship between water supply-demand balance and production/economic activity. Next, the evaluation method, simulation model, the comprehensive basin management method, and so forth that incorporate environmental elements such as water volume, water quality, ecology, and landscape, aiming to form a proper water circulation system throughout the basin, will be explained.
Course Goals Understanding the fundamental techniques for modeling natural and social phenomena related to water resources as a system, and acquiring the ability to collect, analyze, and design data for the sustainable use of water resources.
Schedule and Contents Optimal design theory of water management system (3 times)
Regarding the planning and design of a water management system consisting of facilities for water supply and water disaster prevention, lectures will be given about the method of finding the optimum configuration based on the performance index and the cost index, while paying attention to the setting and formulation of problems, the search method of a solution, and its efficiency.

Management of water resources system and decision support (2 times)
Discussions will be conducted about the management of the water resources system consisting of reservoirs and weirs for both flood defense and water use. Specifically, methods for optimizing operations of facility groups and coping with uncertainty will be explained, and the technology that supports management decision making based on recent technical trends, such as a knowledge base approach, fuzzy theory, and neural network, will also be explained.

Recent topics about water management (2 times)
Deepening understanding about recent topics related to water management and water disaster prevention with a focus on discussions among students. The problems to be covered will vary depending on the year.

World water management (3 times)
The actual condition of water resource management in various basins in various places around the world, climate conditions, geographical conditions, socio-economic development stages, problems, and examples of past efforts will be introduced.

Land surface process model and its application to water management (4 times)
The method of maintenance of input parameters for operating the land surface process model, and the model describing the water circulation in the basin will be outlined, as well as how effective and useful model output elements, such as soil moisture content, evapotranspiration volume, irrigation necessary water volume, snow water volume, and runoff amount are as water resources management support information. Examples of the impact of climate change on water resources utilizing the land surface process model output will be introduced.

Confirmation of learning achievement (1 time)
The achievement degree will be evaluated according to assignments, and feedback will be provided.
Evaluation Methods and Policy The results will be evaluated by combining regular tests and points given for participation.
Course Requirements It is desirable that students have basic knowledge on hydrology and water resource engineering.
Study outside of Class (preparation and review) It is necessary to review based on lecture materials and to complete the report assignments given during the lecture.
Textbooks Textbooks/References not specified. Research papers and so forth will be distributed as necessary.
