Course description and aims

This course focuses on the theoretical aspects and analysis methods of "Water Environmental Flow". Topics include "surface wave caused on the water surface", "water flow caused by spatial density change", and "numerical methods to analysis water environmental flows". In addition to lectures on the theoretical aspects, students will learn how to analyze flow with computational simulations thorough some computer practices.

Student learning outcomes

By the end of this course, student will be able to:
I. Understand the physical features and analysis method of "surface wave of water".
II. Acquire skills to conduct a numerical analysis of "surface wave of water".
III. Understand the impacts of spatial density changes on water flows and their features.
IV. Acquire skills to conduct a numerical analysis of "density driven environmental flow".
