Environmental Transport Processes: Advection and Diffusion Modeling

Understanding how pollutants disperse in air, water, and soil is critical for environmental engineers and scientists. This course demystifies the complex mathematics behind environmental transport processes, helping you analyze real-world contamination scenarios. You will transition from understanding basic fluid mechanics to confidently modeling how substances move through the environment. Through guided step-by-step problem-solving, you will learn to apply the governing equations of advection and diffusion to predict pollutant concentrations over time. In this course, you will: 1. Understand the foundational principles of mass transport, including advection, molecular diffusion, and turbulent dispersion. 2. Calculate pollutant concentrations for instantaneous release scenarios using analytical solutions. 3. Apply the advection-diffusion equation to real-world environmental systems like rivers, lakes, and the atmosphere. 4. Analyze boundary conditions and spatial scales to select appropriate modeling assumptions. 5. Explore modern numerical modeling frameworks and computational approaches used by today's environmental consultants. The course begins with core terminology and physical concepts before guiding you through mathematical derivations and practical, step-by-step problem-solving exercises. You will read clear explanations of complex transport phenomena and practice applying these formulas to realistic environmental scenarios. This course is designed for beginner-level environmental engineering students, science professionals, and consultants looking to build a strong foundation in transport processes. No prior advanced modeling experience is required. Start reading today to master the mechanics of environmental transport and dispersion.
