Short summary
This research investigates how water flows through porous media, focusing on tiny swirling currents called eddies that form around particles. Using experiments and computer, we found that faster flow and larger particles create more eddies, which trap pollutants and slow down their cleanup. A new method is developed to measure these eddies and showed how they can be accurately represented in standard transport models. This study provides a clearer physical basis for predicting pollutant spread.
