Prerequisite: CVEN 3313, Theoretical Fluid Mechanics

Textbook: Required: Hydrology and Floodplain Analysis, Philip D. Bedient Wayne C. Huber

3rd edition, Prentice Hall, 2002

 

Course Goal: To develop the ability to apply fluid mechanic principles to solve water resource engineering problems. The course will provide you with an understanding of the current practices in hydraulic and hydrologic Engineering and will provide you practical experience in the use of software tools for analysis and design of water resources engineering applications. You will be required to be able to synthesize this knowledge in a real-world design project. This course will also prepare you for further study in open channel flow, surface water hydrology, sediment transport, and environmental fluid mechanics.

Homework: Assignments are to be turned in before class the day they are due. Late homework will be accepted only if you obtain my permission before the due date or there are extenuating circumstances.

Reading Assignments: Your comprehension of the lectures is significantly improved if you have some background, therefore you are required to read the material to be covered that day before the lecture period. Students will be asked to answer questions in class during the year. If you do not want to be asked questions during class, please let me know (personally, email or any other method of communication).

Design Projects:  You will gain experience synthesizing information from your reading, the lectures and other sources, including manufacturers and suppliers, you will learn to use software that is widely used in engineering practice, and you will gain experience preparing professional reports. The project does not have a single correct answer and is designed to give you experience using engineering judgment.

Tests: Two In-class exams will be given. The final exam will be an oral presentation of your final project.
