Open Access Resources for Teaching & Learning

The COVID-19 pandemic caused a sudden shift to online teaching for most universities in the United States, and many globally. With little time to prepare, water resource and hydrology professors and lecturers must generate online content rapidly for at least the spring and summer semesters of 2020, with an increasing possibility this format will extend into the fall 2020 term. At the same time, there is large variation in access to and preparation for online delivery among institutions and individual faculty. In the hydrologic sciences, we expect preparation for the transition to online instruction and the resultant learning to vary based on program size, institution, instructor experience, and availability of instructional support. Taken together, there is a significant risk that hydrologic instruction will divide into “haves” and “have nots” as a result of these critical differences. Equal access to critical support and instructional resources during the transition from traditional to distance learning in response to the COVID-19 pandemic is critical to closing this gap and providing equal access to high quality instruction in the hydrologic sciences. Thus, our goal is to enable access to educational infrastructure and training for instructors, and ultimately students, in the hydrologic sciences in response to the COVID-19 pandemic.

Among many resources we developed and organized, I put teaching materials for several of my courses on CUAHSI's HydroShare. The full database we assembled can we accessed here. In addition to the materials posted on HydroShare, selected video recordings to supplement my lecture recordings are posted below.

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.

Short course on Stream Solute Tracers

v2.0 - HydroLearn Module
This short course is now freely available and significantly more organized via HydroLearn. This 'tracer boot camp' covers the design, execution, and interpretation of stream solute tracer studies.

v1.0 - (OLD STUFF) CUAHSI Virtual University lectures
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)
