Modeling Pesticides in the Aquatic Environment
Principles and Methods of Modeling Transport and Fate (Course ID: HYD-403)
Hosted by Northwest Environmental Training Center

Description: This workshop will focus on modeling methodologies as they are typically used to estimate pesticide concentrations in surface water. The course will follow a hands-on approach and will be geared toward environmental scientists with minimal modeling experience. The course is designed to instruct attendees on the use of these models so that the attendees may reproduce and interpret generated pesticide assessments in the future.

Course material will be presented through interactive lectures with accompanying hands-on exercises. The exercises will be based on a single example so the students build a surface water assessment from the ground up. This will simulate a normal modeling risk assessment process which would include parameter selection, simulation, output, and output interpretation. The US EPA has developed a model shell called PE5 that combines the field-scale runoff/leaching model PRZM with the surface water model EXAMS to estimate pesticide concentrations in surface water. Using this shell, students will be guided through a typical surface water exposure assessment along with examination of results. This will be followed by examination of PRZM and EXAMS model use outside of the shell.
