Solving Environmental Transport Processes: Diffusion and Point Sources

Understanding how pollutants disperse in air, water, and soil is crucial for protecting ecosystems and public health. This course guides you through the foundational physics and mathematics of environmental transport processes without requiring advanced prior engineering experience. You will transition from understanding basic fluid dynamics to confidently calculating pollutant concentrations from continuous point sources. Through step-by-step written explanations and practical problem-solving scenarios, you will learn to predict environmental impacts using standard analytical models. What you'll learn: Understand the fundamental principles of advection, diffusion, and dispersion in environmental media; Calculate pollutant concentration profiles from continuous point sources using analytical solutions; Apply boundary conditions to model transport in rivers, lakes, and the atmosphere; Analyze the behavior of steady-state and transient transport systems; Evaluate environmental data against modern regulatory safety limits and compliance standards. The course begins with essential terminology and the governing transport equations before guiding you through structured, written problem-solving exercises. You will explore practical calculations that form the backbone of modern environmental impact assessments. This course is designed for beginners in civil engineering, environmental science students, and professionals looking to brush up on transport phenomena, with no advanced engineering prerequisites required.
