Environmental Transport Processes: Continuous Source Modeling

Understanding how pollutants disperse from a permanent, ongoing release is critical for managing water quality, air pollution, and environmental health. This text-based course introduces the core principles of environmental transport processes, focusing specifically on continuous source modeling. You will learn how to conceptualize, set up, and solve the transport equations that describe how contaminants behave when they are constantly introduced into an ecosystem. Starting with fundamental definitions of diffusion, advection, and dispersion, you will build a solid theoretical foundation before moving on to practical modeling scenarios. Through clear written explanations and step-by-step mathematical breakdowns, you will explore how physical boundaries, flow velocities, and decay rates impact pollutant concentration profiles over time and space. What you'll learn: Understand the fundamental physics of advection, diffusion, and turbulent dispersion in environmental systems; Derive and apply the continuous source transport equations for rivers, estuaries, and the atmosphere; Analyze the spatial distribution of contaminants under steady-state and transient conditions; Account for decay, reaction rates, and boundary conditions in your transport calculations; Evaluate modern environmental modeling assumptions and identify potential sources of error. This course begins with essential fluid mechanics and transport terminology before guiding you through one-dimensional, two-dimensional, and three-dimensional analytical solutions for continuous releases. This course is designed for beginners in environmental engineering, hydrology, or civil engineering who want to build a strong quantitative foundation in pollutant transport, with no advanced prerequisites required.
