AEN 536 Fluvial Hydraulics          

Fall 2001

Description:  Rainfall physics, principles of erosion on upland areas and construction sites, stable channel design in alluvial material, mechanics of sediment transport, river mechanics, reservoir sedimentation.

Prerequisites:  CE 461G, ME 330, Engineering standing.

Outcomes:  At the conclusion of this course, each of you should be able to:

1.      Perform frequency analysis for flood peak and rainfall data.

2.      Calculate runoff hydrographs and peak flows.

3.      Design erodible and non-erodible channels.

4.      Assess performance of selected hydraulic structures (e.g., spillways and culverts).

5.      Perform channel and reservoir routing.

6.      Estimate erosion and sediment yield.

7.      Evaluate performance of sediment control structures and practices.

8.      Characterize and design stable fluvial channels.

9.      Understand basic monitoring principles.

10.  Understand basic modeling principles.

11.  Develop a pollution prevention plan.

12.  Be able to correctly operate selected hydrologic/hydraulic modeling software packages.

Instructor:  Dr. D.R. Edwards, 109 Agricultural Engineering Bldg.  Office hours Tuesday and Thursday 2:00-3:00 or by appointment.  Office phone 257-3000, ext. 109.  E-mail dedwards@bae.uky.edu

Grading:  The following activities will comprise the indicated percentages of your total grade:

Individual Homework 45%
Team Projects (4) 45%
Participation 10%

The maximum percentages required to earn given letter grades are:

            A            92%

            B            84%

            C            76%

Class Hours:  12:30-1:45, Tuesday and Thursday.

Attendance:  Attendance is optional, but it will affect class participation and presentation components of your grade.  Excused absences such as illness, official trips as part of other courses and religious holidays will not count against class participation and deadlines.


1.      Except for cases of excused absence, homework is due at the beginning of the class period listed as the due date. Late assignments will not be accepted.

2.      Use engineering paper for homework with header information appropriately supplied (see old homework solutions).  I expect homework to be performed in standard engineering format (i.e., Given, Required, Solution; intermediate results with single underline, final result with double underline or box).  Cite sources of all coefficients, equations, figures etc. used.  Use a pencil, and print legibly.  You may use a computer if and when appropriate or advantageous, but you are responsible for adequately documenting your work.

3.      I hope you will work together in solving homework problems.  The work you turn in, however, must be a reflection of your own efforts rather than a substantial copy of another person's work.

Announcements:  I will use e-mail distribute announcements.  BAE students should already have e-mail accounts; if not, then let me know.  Any non-BAE students who have accounts on other mail servers need to let me know their e-mail address.
