Scientific study of water in terms of occurrence, distribution, circulation, physical and chemical properties, reaction with the environment.

3. What is Groundwater hydrology? The science that deals with occurrence, distribution, movement of water below the ground surface including quality and quantity aspects The science that deals with occurrence, distribution, movement of water below the ground surface including quality and quantity aspects

4. Where does Groundwater exist? It occupies and flows through It occupies and flows through Porous media (interconnected small openings within the solid matrix) Fractured media (relatively large openings in plane of fracture) Karst or Large Passages (dissolution cavities or caves)
