[Class Outline]
Lectures and exercises in hydrodynamics and hydraulics will provide students with a foundation for environmental management in river basins. Students will learn to represent fluids, such as water and air, in mathematical terms. Students will learn the conservation laws of mass, energy, and momentum in the mechanics of a perfect fluid, which models the fundamental mechanical behaviour. Students will learn about viscous fluid mechanics and the equations of fluid motion, including laminar and turbulent flows. Students will practice the lecture content above through exercises.

A grade will be given on a comprehensive evaluation of the results of exercises (30%), mid-term examination (35%), and final
examination (35%) based on the degree of understanding of the lecture objectives. However, if the attendance rate for the
entire lecture, including practices, is less than 80%, it will not be evaluated. The evaluation criteria are that if you can
reliably solve the lecture exercise problems and similar problems, you will be at the 60% level.

Take the lecture ”Calculus and Exercises 1” or similar contents in advance. Ability to perform calculations using a scientific
calculator or PC (Excel, etc.).
- At the lecturer’s room in the Omiya campus during the lunch break on the lecture day. It is highly recommended that you make a reservation by an e-mail to the Professor in advance.
- Upload additional content explanations and related materials to the lecture folder.
- This lecture is an introductory lecture on fluid mechanics/hydraulics, and it cannot be said to be easy at all, as there are many mathematical formulas. However, the basic laws are only the three conservation laws of energy, momentum, and mass, and the idea is simpler than it appears.
- Currently, due to global warming and torrential rains, appropriate environmental management of the hydrosphere, including rivers and lakes, is becoming increasingly important. In this lecture, you will learn the basics of mechanical thinking and methods that form the basis of environmental management of the aquatic environment. The professor hopes you will study hard to obtain the essentials in basic fluid mechanics/hydraulics.
- Course that cultivates an ability for utilizing knowledge
- Course that cultivates a basic self-management skills
