TEXT:

Davis, M. L., and Cornwell, D. A.  Introduction to Environmental Engineering,”  Third Edition, McGraw-Hill, 1998.  ISBN:  0-07-015918-1.

 

COURSE GOALS:

·        To understand the nature of water and air pollutants

·        To learn to apply engineering solutions to water and air pollution problems

·        To understand environmental regulations and their consequences on the design pollution control systems

 

SUMMARY OF COURSE OBJECTIVES:

At the conclusion of the course the student will be able to:

·        Apply basic science concepts (chemistry, physics, biology and mathematics) to understand the nature and impact of pollutants on the aquatic and air environments

·        Evaluate the impact of pollutants upon these environmental media and to determine the degree of environmental control to minimize this impact while complying with federal environmental regulations

·        To apply engineering criteria to basic engineered pollution control systems

 

CONTRIBUTION OF COURSE TO MEETING THE PROFESSIONAL COMPONENT:

This course provides the student with the necessary background to perform entry-level professional work in environmental engineering.

 

RELATIONSHIP OF COURSE TO PROGRAM OBJECTIVES:

This course satisfies the environmental engineering components of the civil, agricultural and geological engineering programs.

* 5% of the participation/attendance grade will be deducted for each unjustified absence.  Justified absences are death in the family and illness (medical proof required).

 

Final grades will be determined by converting the total numerical ranking into a letter grade as follows:

FINAL GRADE SCALE

A+ = 97-100

B+ = 87-89

C+ = 77-79

D = 60-69

A = 94-96

B = 84-86

C = 74-76

F < 60

A- = 90-93

B- = 80-83

C- = 70-73

 

 

GENERAL POLICIES

There will be one midterm exam and a final comprehensive exam in this course.  Unless there is a justifiable reason, the student is expected to take both exams (see dates in syllabus).  The final exam is comprehensive (includes all the material covered during the semester).

Students enrolled in this course (2.0 cr) are expected to attend one of the two laboratory sessions (1.0 cr).  Laboratory grade will be based on student attendance, quizzes, participation and laboratory reports.  Additional information on lab experimentation and student responsibilities will be provided during the first laboratory class.

Homework problems are due on the dates shown in the syllabus table.  These problems may be worked out in teams, but each student is expected to turn his/her own assignment.  Late homework will be penalized 20 percent for each workday after the deadline.  In order to take full advantage of the points obtained through the homework the student is encouraged to make sure that his/her answers are scientifically correct, and that the work is presented in a professional manner.  Please check the class web site to download the assignments corresponding to the homework dates shown in the syllabus.

A computer program (a model of dissolved oxygen in streams) will be assigned March 16.  The program must be written in BASIC, C, FORTRAN, MATHCAD (or other advanced computer language approved by the instructor).  This computer assignment must be turned in as a technical report including: a) front page, b) introduction, c) mathematical description of the model, d) numerical input e) numerical output, and f) graphical presentation of the output {only computer-generated graphics are acceptable} g) conclusions h) printout of the program as an appendix.  Deadline for submission of the program is December 7 (in class).  Other rules given for homework are also applicable to this report.  Students are encouraged to work in teams, however every student must turn in an original report and computer program.

STUDENTS WITH DISABILITIES

If you have or believe you have a disability, you may wish to self-identify.  You can do so by providing documentation to the Services for Students with Disabilities, SSD, located at Garcia Annex (Phone: 646-6840).  Appropriate accommodations may then be provided for you.

 

If you have a condition which may affect your ability to exit safely from the premises in an emergency or which may cause an emergency during class, you are encouraged to discuss this in confidence with the instructor and/or the director of SSD.  If you have general questions about the Americans with Disabilities Act (ADA), call the ADA coordinator at 646-3333.
