Erosion and Aquatic Ecosystems

Dr. Rudy Rosen introduces himself as the instructor for Texas Aquatic Science, a course based on a textbook he authored in collaboration with various institutions. The course is modeled after Missouri's aquatic curriculum and funded by several organizations. The lesson focuses on watersheds, exploring their impact on water bodies, human activities, pollution types, erosion, sedimentation, and Texas's natural regions. It encourages students to consider their role in influencing water quality in their watershed.
