Master the Dynamics of Our Planet: An In-Depth Guide to Environmental Fluid Mechanics
Have you ever watched smoke rise from a chimney, wondered how dust storms form, or pondered the movement of pollutants in groundwater? These phenomena are all governed by the principles of Environmental Fluid Mechanics (EFM). This fascinating branch of science sits at the intersection of fluid dynamics, environmental engineering, and geophysics, providing the tools to understand and model the natural flows that shape our world.
For postgraduate students, researchers, and professionals in Civil Engineering, Mechanical Engineering, and Environmental Sciences, a deep understanding of EFM is no longer a niche skill—it's a critical necessity. Addressing modern challenges like climate modeling, pollution remediation, and sustainable energy requires a firm grasp of how fluids behave in our environment.
About the Course: Delving into Naturally Driven Flows
This comprehensive 8-week course is designed to introduce and demystify the core concepts of Environmental Fluid Mechanics. The course focuses on buoyancy and density-driven flows—those that occur due to differences in temperature, salinity, or particle concentration. From the dispersion of industrial exhaust to the spread of saline water in aquifers, these flows are ubiquitous in nature and industry.
Students will be equipped with both analytical and experimental techniques used to model these complex flows in various settings: the atmosphere, oceans, and subsurface. The curriculum is built on a solid foundation of applying the conservation laws of mass, momentum, and energy to derive solutions and predict the behavior of environmental flows.
Learn from an Expert: Instructor Profile
The course is led by Dr. Chunendra K. Sahu, an Assistant Professor in the Department of Civil Engineering at IIT Kanpur. Dr. Sahu brings a wealth of international research experience to the classroom:

Essential Reading Materials
To supplement the lectures, the following textbooks are highly recommended:
- Cushman-Roisin, B. (2022). Environmental Fluid Mechanics, 1st Edition. John Wiley & Sons. A modern and dedicated text on the subject.
- Kundu, P.K., Cohen, I.M., & Dowling, D.R. (2015). Fluid Mechanics, 6th Edition. Academic Press. A classic and comprehensive reference for fundamental fluid dynamics principles.
Industry Relevance and Applications
The principles taught in this course have direct and significant industrial applications. Industries that will find this knowledge invaluable include:
- Companies involved in air and water pollution remediation and control.
- Environmental consulting firms.
- Energy sector companies dealing with subsurface flows (e.g., geothermal, carbon sequestration).
- Government bodies and agencies engaged in environmental policy-making, regulation, and disaster management.
Understanding how pollutants disperse in air or water, how to model the spread of contaminants, or how to harness natural convective flows for energy are just a few examples of the practical skills gained.
