Generation

## Aquifer Permeability **Permeability** is the measure of how easily water can flow through the pore spaces and fractures in an aquifer material. It depends on the size, shape, and connectivity of these openings. High-permeability materials like gravel and coarse sand allow water to move quickly, while low-permeability materials like clay restrict flow. ## Common Misconception **Misconception:** "High porosity always means high permeability." **Reality:** Porosity (the amount of empty space) and permeability (how well those spaces are connected) are different properties. Clay, for example, can have very high porosity (40-70%) but extremely low permeability because its tiny pore spaces are poorly connected and create high resistance to water flow. Conversely, well-sorted gravel may have lower porosity (25-35%) but much higher permeability due to large, well-connected pore spaces.
