GEOG 110:  Modeling of Environmental Systems

Fall 2005

Course Description:

 

The environment is a dynamic and living system in which the interactions of numerous biological, biophysical and biogeochemical processes determine the rate and direction of change.  A comprehensive understanding of the past and current status of the environment and prediction for its status in the future cannot be achieved without the help of computer-based models.  On the one hand, computer-based models can integrate natural history, physiological, and ecological information that has been gathered over may years by many people; on the other hand, computer-based models can simulate the environment in various hypothetical conditions (e.g. a common hypothetical condition in global climate change is doubling the CO2 concentration).

 

GEOG 110 takes a system view of the environment, and introduces the fundamental concepts and approaches in modeling of environmental systems.  Essentially all environmental processes are driven by energy associated with the flow of matter (e.g. water and nutrients).  The course will be focused on modeling the dynamics of energy and matter flow through the environment, including the energy and matter flow in the natural environment, and in the presence of human disturbance. Throughout the course, we will use the Stella software as a tool to assist us in modeling environmental systems. The course is composed of three components: instructor lectures, hands-on lab experience in using Stella to model environmental systems, and in class discussions of exercises.  The objectives of the course include:

 

1.     Developing an understanding of the fundamental principles of how environmental systems work

2.     Developing an understanding of systems thinking

3.     Making proficient use of the Stella software in solving systems problems

Grading Policy:

 

Final course grades will be determined using the following formula:

 

Midterm 1 (Wednesday, October 5, 2005): 15%

Midterm 2 (Wednesday, November 9, 2005): 15%

Final Exam: (Saturday, December 10, 2005 at Noon) 30%

            Labs: 30%

            Exercises: 10%

 

Note: No make up tests are given. Any student failing to take an exam will score zero for that test unless a legitimate, documented reason is presented. In the latter case the student will have the average score from their other exams added in place of the missing test.
