## Teaching Resources

In response to the COVID-19 pandemic and the near-instantaneous switch to distance learning, I am making much of my teaching content available for public use. The video playlists below include lectures, examples, exercises, and more from some of my recent courses. My hope is that these will be a resource for instructors and students.

## Water Quality Modeling

This playlist is organized in parallel with the textbook Surface Water Quality Modeling by S. Chapra.These videos are not formally associated with the textbook in any way, but have been developed to supplement the learning of students in my course. I have organized the videos with titles as "Lecture X" to help users see which of Chapra's Lectures (i.e., chapters) are associated with each video.

List of videos included in the Water Quatliy Modeling playlist above, organized by the associated Lecture in the Chapra text. In the future I will add the slides that go with each lecture and so students take notes along with each of these videos.

1. Introduction

2. Reaction Kinetics

3. Mass Balance, Steady-State Solution, and Response Time

4. Particular Solutions

5. Feedforward Systems of Reactors

6. Feedback Systems of Reactors

8. Diffusion

9. Distributed Systems (Steady-State)

10. Distributed Systems (Time-Variable)

14. Rivers and Streams

19. BOD and Oxygen Saturation

20. Gas Transfer and Oxygen Reaeration

21. Streeter-Phelps: Point Sources

22. Streeter-Phelps: Distributed Sources

24. Photosynthesis/Respiration

25. Sediment Oxygen Demand

27. Pathogens

30. Heat Budgets

31. Thermal Stratification

## Fluid Mechanics

## Short course on Stream Solute Tracers

As part of CUAHSI's Virtual University I have offered a short course focused on stream solute tracers. While designed as a synchronous, online course for those enrolled, these videos have been requested by others. You can download the syllabus, including the prereads for each lecture, here. The slides that I used for each lecture are also linked below so you could take notes along with the lectures as you see fit.

Lecture 1: Stream solute tracer intro (what, why, basics) - (get the slides here)
