Environmental Engineering Design: Managing Saltwater Intrusion in Rivers

As sea levels rise and coastal infrastructure faces new challenges, protecting freshwater rivers from saltwater intrusion is a critical task for modern civil and environmental engineers. Understanding how to evaluate and manage these estuarine dynamics is essential for preserving ecosystems and urban water supplies. This text-based course guides you through the core principles of hydraulic design and environmental assessment, using real-world river management scenarios as a foundation. You will gain the analytical skills needed to evaluate saltwater migration, assess environmental impacts, and design sustainable engineering interventions. What you'll learn: - Understand the fundamental physics of saltwater intrusion and estuarine density currents. - Analyze the environmental and structural impacts of salinity on freshwater ecosystems and municipal infrastructure. - Evaluate engineering solutions, including salt runoff barriers, flushing locks, and tidal gates. - Incorporate modern climate change projections and sea-level rise scenarios into hydraulic design models. - Apply basic environmental impact assessment workflows to evaluate river restoration projects. The course begins with essential terminology, fluid mechanics basics, and salinity dynamics before moving into practical engineering solutions and design evaluations. You will progress from foundational theory to reviewing modern, sustainable water resource management strategies through detailed written explanations and guided analysis. This course is designed for aspiring civil and environmental engineers, students, and sustainability enthusiasts seeking a clear, beginner-friendly introduction to water resource engineering without any prior advanced math prerequisites.
