Water Resources Utilization

Water Resources Utilization
Water is a resource that maintains lives. The water cycle, water utilization, water resources development and management, flood control, and river environments are explained in this lecture. Moreover, water issues on a global scale and water utilization abroad are introduced by some examples.

Environmental Impact Assessment
Environmental impact assessment is a process by which projects and plans are evaluated by taking the environment into account. In this process, the environmental impacts of development projects and plans are investigated, forecasted, and evaluated in advance, and the results are announced and comments are included in these projects and plans. The significance and necessity of environmental impact assessment, its system, and its methods are explained, and some examples are given.

Research Topics
  • Impact assessment of climate change and human activity on the Tedori River Basin

    The impacts of climate change and human activity on water resources, nutrients (e.g., nitrogen, phosphorus, and silica), and water temperature are assessed in the Tedori River Basin by using numerical simulation and field observation. Adaptation strategies to reduce these impacts are also investigated.

  • Development of water management methods compatible with water saving and heat injury prevention in rice crops

    Water and soil environments (e.g., water temperature, soil temperature, and oxidation-reduction potential), transpiration of rice, and temperature of leaves and heads are monitored under water saving cultivation conditions such as SSC (Soil Saturated Culture) and AWD (Alternative Wetting and Drying). Qualities of rice are examined and water management methods compatible with water saving and heat injury prevention in rice crops are developed.

  • Reconstruction of the dyke system in the flood-prone rice-growing area of the Mekong Delta

    Adaptations to flooding, such as construction of dykes, planting flood-resistant rice varieties, and selection of sowing dates, are clarified for the flood-prone rice-growing area of the Mekong Delta. Moreover, the effects of flooding on agricultural land environments are elucidated. Water and land management strategies that are compatible with flooding are presented.

Expectations of Students Try many things and meet various people.
