Porosity refers to the amount of open space within a rock, while permeability measures how easily water can flow through those spaces.

is the branch of geology that focuses on the distribution and movement of groundwater in the soil and rocks of the Earth’s crust (typically in aquifers). Introduction to Hydrogeology HydrogГ©ologie

Hydrogeology is the study of how water interacts with geological systems. Unlike surface water hydrology, which focuses on rivers and lakes, hydrogeology explores the hidden "groundwater" stored beneath our feet. This field is essential for ensuring sustainable water supplies and protecting environmental health. Why It Matters Porosity refers to the amount of open space

Underground layers of water-bearing permeable rock, gravel, or sand. Unlike surface water hydrology, which focuses on rivers

Groundwater provides nearly half of the world's drinking water and is a primary source for agricultural irrigation.

Understanding how water moves helps experts track and clean up pollutants from industrial or agricultural runoff. Key Concepts
