Course Description: Chemical, physical, and biological processes defining surface water quality and
other hydrologic feature that affect surface water quality; construction and application of computer
models for lakes and streams.

Objectives: Familiarize students with concepts, terminology, chemistry, and math skills required to solve
and model surface water quality problems.

Topics Covered:

• Introduction to surface water impairment; history of water quality modeling

• Chemical Reaction chemistry

• Completely Mixed Systems (lakes, ponds): oxygen, nutrients, pathogens

• Incompletely Mixed Systems (streams, rivers): oxygen, nutrients, pathogens

• Watershed Systems

• Model calibration, testing, sensitivity analysis

• Modeling for Total Maximum Daily Loads (TMDLs)

• Water Quality Models: LAKE2K, QUAL2K, SWAT, BASINS
