TxDOT Hydraulic Design Manual

Description: Hydraulics is a broad area with many sub disciplines. This class will focus on fundamental hydraulic principles as illustrated through laboratory experiments. Rather than attempting to cover the entire field, we will focus in detail surface water hydrology, groundwater hydrology, open channel flow, and flow in pipes. Hydraulics is very much a laboratory oriented course and cannot be properly learned in the absence of a laboratory. Laboratory exercises are featured prominently in the class and grading.

  Mastery of fundamental concepts will facilitate the student in learning more detailed hydraulics applications throughout his/her career. Although computer codes are frequently used in engineering practice to perform many of the calculations we will cover, the computer codes change with time whereas the fundamental principles upon which the codes are based do not change. The class will focus on fundamentals rather than cook book solutions.

Students are responsible for familiarity with all assigned reading. Quantitative problems on tests will be limited to problems similar to homework problems and problems solved in class. Conceptual and fact questions will be drawn from reading, presentations, and online assignments.

Class format will consist of a combination of brief lectures, presentation of auxiliary materials (e.g., subject matter videos), class exercises, and solution of homework problems. It is assumed that the student has read the textbook chapter and attempted all homework prior to the class period where it is assigned. Unless specifically requested homework does not have to be turned in but may be the subject of quizzes.

Lesson 1: Introduction

Class Introduction, Chapter 1: Fundamental Properties of Water
Chapters 1 and 2 of Textbook

In the 1960's Dr. Hunter Rouse, an expert on fluid mechanics, made a series of videos with physical models made to demonstrate many of the concepts discussed in this class. The videos are excellent and the physical models are much more instructive than the computer simulations prevalent today. I recommend that you watch all of them. The link to the full files is:

Basic Hydraulic Principles

Closed Conduit Flow

Note: presentations are put online in video format that allows you to watch the videos inside. It works for me if you right click and download the PowerPoint file then open it on your computer. Just clicking on the link gives nonsense, maybe a computer savy student can explain why? Also you may have to put in the .pptx file dot delimiter when saving.

Pipe Flow Presentation

Note: This chapter is a review of material covered in Thermal-Fluid Systems, a prerequisite to this class. If you chose to take this class without the prerequisite you are responsible for learning much of the material on your own.

Final Exam Schedule

Final Exam Cheat sheet: two 8.5x11 sheets/ one side per sheet (equations)

Tuesday May 12, 1-3:45 PM


Laboratory Schedule


Laboratory 15%, 2 midterm exams (2 20%), final exam 25%. Quiz average (20%). Laboratory grade includes attendance, active participation, and lab reports. Tests will all be closed book. A sheet of equations, graphs, and constants will be provided in advance of the test.  If a test is missed the final exam will serve as the makeup exam. Grade on the final exam will be used to replace the lowest prior exam or quiz score. The times on the syllabus will change during the semester depending upon where we are in class. However the test dates will not change. The student should clear test dates from work and other schedules in advance.

Examinations: During examinations all books, mobile phones, and notes are to be left along the wall at the front of the room. Only the allowed calculators are allowed.

Allowed Calculators

The following will be the only calculators allowed in exams:

These are the same calculators that are currently being allowed in the Fundamental of Engineering (FE) and Professional Engineering (PE) exams ( It is your responsibility to get acquainted with the features of the calculator you decide to use. I recommend that you use this calculator for all your work (including other courses) since this will help you learn how to use all the features of your calculator

Absence from laboratory exercises must be approved in advance.  Anyone retaking the class can accept last year's laboratory grade or retake the lab.

Graduate Students taking Undergraduate Class for Graduate Credit

Graduate students taking Hydraulic Engineering for graduate credit must prepare and deliver a class session including an enhanced mini-lecture and an interactive cooperative classroom exercise. This session will be reviewed and approved by the instructor in advance.

Policy on Cheating

  Students are expected to be above reproach in all scholastic activities. Students who engage in scholastic dishonesty are subject to disciplinary penalties, including the possibility of failure in the course and dismissal from the university. "Scholastic dishonesty included but is not limited to cheating, plagiarism, collusion, the submission for credit of any work or materials that are attributable in whole or in part to another person, taking an examination for another person, any act designed to give unfair advantage to a student or the attempt to commit such acts." Regents' Rules and regulations, Part One, Chapter VI, Section 3, Subsection 3.2, Subdivision 3.22. Since, scholastic dishonesty harms the individual, all students, and the integrity of the university, policies on scholastic dishonesty will be strictly enforced. In short, cheating will not be tolerated.
