River engineering was and has been an empirical engineering, but scientific knowledge and methodology are also applied in modern river engineering. In this course, students will study the basics of terrestrial hydrological cycle for river engineering. Then, students will study three major aspects of rivers and water resources management: flood protection, water utilization, and the environment, that leads to a comprehensive understanding of rivers and water resources. Specifically, topics/themes include hydrological cycle and runoff analysis, flood control planning and statistical hydrology, water disasters from the past to the current, water resources and water use, and the environment and development of rivers and water-resources. In addition, latest important topics such as climate change and water will be introduced.
This course has two aims. The first aim is to let students obtain a set of basic and comprehensive knowledge and perspective at undergraduate level for each topic/theme written above, The second aim is to let students to experience for himself/herself the following three exercises individually or by group: development of runoff modeling, application of hydrological statistics to actual data and its discussion, and investigation on an actual example of river disaster and management.
By the end of this course, students will be able to:
1) obtain a set of basic and comprehensive knowledge and perspective at undergraduate level for each topic/theme: hydrological cycle and runoff analysis, flood control planning and statistical hydrology, water disasters from the past to the current, water resources and water use, and the environment and development of rivers.
2) explain comprehensively river and water resources management in terms of three major aspects: flood protection, water utilization, and the environment, based on basic knowledge and perspective written in 1).
3) complete three important exercises individually or by group: development of runoff modeling, application of hydrological statistics to actual data, and investigation on an actual example of river disaster and management.
River, Hydrology, Water cycle, Water resources, Water disasters
|✔ Specialist skills||Intercultural skills||Communication skills||✔ Critical thinking skills||Practical and/or problem-solving skills|
Lecture, discussion and small-exam are mixed in every lesson. There are opportunities of group-based investigation and presentation. Students are requested to individually compute a rainfall-runoff model and an extreme value analysis. Because of the nature of river that is inherently integrated and complicated, topics of 1-15 may be integrated in every lesson.

Handouts will be distributed in the class.
Reports (or exams) will be assigned to three themes: hydrological cycle and runoff analysis, water disasters and flood control planning, and the environment and development of rivers/water-resources. Each theme will cover approximately 1/3. For each theme, several small reports and small exams rather than a single report may be assigned. Assessment is based on the quality of the written reports (or answer sheets).
