Outline of Final Research Achievements

Darcy's law is generally applied to water movement through porous media. However, it has been indicated that flow under high Reynolds numbers does not always satisfy Darcy's law, and it is known as non-Darcy flow. This study developed a numerical model for non-Darcy flow based on Lagrangian method. Through seepage experiments in soil layer, the rage in which Darcy's law could be applied was confirmed while referring to the previous researches. The numerical model developed was also validated.
