|Instructor name||NAKAMURA KIMIHITO (Graduate School of Agriculture Professor)|
|Outline and Purpose of the Course||Lecture on basic theory of water and substances transport in soil necessary for dealing with various environmental problems related to soil such as water and various chemicals management in agricultural soil, groundwater ans soil contamination, and desertification. In particular, we describe soil composition and structure, soil water energy, soil water movement, soil air, soil temperature and mass transport in soil. It is fundamental for applied disciplines such as irrigation and drainage, hydrology, and groundwater science.|
Understanding the mechanisms of water movement, heat transfer, solute transport, gas movement in soil.
Understanding the basic knowledge necessary for solving environmental problems related to soil.
Developing the ability to tackle the exercises by yourself.
|Schedule and Contents||
1. Introduction of soil physics
(relationship between soil and human life, function of soil)
2. Generation of soil and three phase distribution
(weathering process, three phase distribution of soil)
3.-4. Construction and structure of soil
(constituent materials of soil, clay mineral, particle size analysis, specific surface area)
5.-6. Soil water
(capillary rise, soil water energy state, soil water retention curve)
7.-8. Water flow in saturated soil
(flow in capillary, Darcy's law, hydraulic conductivity)
9.-10. Water flow in unsaturated soils
(unsaturated hydraulic conductivity, Richards equation, water vapor movement)
11. Heat transfer in soil
(heat balance, heat conduction, simultaneous movement of heat and soil water)
12. Solute transport in soil
(convection, diffusion, dispersion, convection-dispersion equation, adsorption isotherm)
13. Soil air and its movement
(composition of soil air, gas movement in soil)
14. Groundwater and its pollution
(unconfined aquifer, confined aquifer, groundwater pollution)
15. Final examination/ Learning achievement evaluation
16. Feedback: Set a period and accept and answer questions from students
|Evaluation Methods and Policy||
Final examination (60 marks) and Active participation/submissions (40 marks).
The evaluation criteria and policies are in accordance with the "Evaluation Criteria and Policies" described in the Student Handbook of the Faculty of Agriculture for the relevant year.
|Study outside of Class (preparation and review)||It is necessary to try to understand the explanation by referring to the materials distributed during the lecture, and to positively address problems in the materials and reference books.|
|Textbooks||Textbooks/References||Handouts will be distributed.|
