Course description and aims

This course provides the fundamental knowledge and techniques to understand, assess, and manage aquatic ecosystems. It covers aquatic chemistry, biogeochemistry, and aquatic ecology while the applied aspects emphasize ecosystem managements taking rivers and lakes as examples.
Aquatic ecosystems have close relation to human activities, including flood control, water use, water environment, fishery, and so forth. Therefore, it is critically important to understand how aquatic ecosystems are complex, dynamic, and vulnerable from the physical, chemical and biological perspectives in order to properly assess and conserve aquatic ecosystems in relation to human activities. This lecture aims to provide such fundamental knowledge as well as techniques for practical applications so that students can obtain the overview of ecosystem management.

Student learning outcomes

By the end of this course, students will be able to:
1. Explain basics of biogeochemical process and water quality formation process in water environment.
2. Describe key components of the aquatic ecosystem and major ecological processes.
3. Present the concepts and techniques that are useful for environmental management, based on the hydraulic characteristics of each body of water including rivers , lakes, and coastal areas.


Water Chemistry, Microbiology, Trophic Relations, Aquatic Ecosystem, Water Environmental Management

Competencies that will be developed

Specialist skills Intercultural skills Communication skills Critical thinking skills Practical and/or problem-solving skills

Class flow

Basically, one of key components/processes of aquatic environment will be described in each class. About 80 minutes of lectures including exercises will be allocated, and about 20 minutes will be allocated to subsequent quizzes and questions. In addition, report assignments will be given in the middle and end of the term.

Out-of-Class Study Time (Preparation and Review)

To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 40 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.
