Environmental Transport Processes: Diffusion, Advection, and Dispersion

Understanding how pollutants and substances migrate through natural systems is critical for environmental protection and engineering. This course provides a clear, structured guide to solving the fundamental transport equations that govern our environment. You will transition from understanding basic physical concepts to confidently setting up and solving mass transport problems, enabling you to predict pollutant concentrations over space and time. What you'll learn: 1. Learn the fundamental physics of diffusion, advection, and dispersion in environmental systems. 2. Master the mathematical formulations of Fick's laws and the advection-dispersion equation. 3. Calculate pollutant concentration profiles in rivers, lakes, and groundwater aquifers. 4. Apply boundary conditions to solve transport equations for real-world scenarios. 5. Understand modern numerical approximation concepts and basic computational modeling frameworks. 6. Practice step-by-step problem-solving techniques for environmental engineering assessments. The course begins with foundational definitions of mass transfer, fluid dynamics basics, and transport mechanisms. You will then work through guided analytical problems, gradually moving from simple diffusion to complex multi-dimensional dispersion scenarios. Designed for beginning engineering students, environmental consultants, and science professionals, this course requires only basic calculus and physics.
