Hydrogeology is a branch of geology, the study of rocks and the structures that are formed over vast periods of time. The way that sediments have been deposited to create different layers of rock beneath the surface, or the way that rocks have been heated and folded over millions of years to create complex structures are the subjects of geology.
Hydrogeology looks at how water interacts with geological systems. But there is more to hydrogeology than wet rocks. Water is a vital natural resource for people all around the world - whether it is piped to homes or drawn out of wells. Understanding where it is and how it moves under the ground is essential in protecting this resource.
By using geological maps and taking samples of underground and surface water for analysis, hydrogeologists are able build detailed pictures of how water flows through porous rocks underground.
Why is Hydrogeology important?
Some parts of the world are blessed with frequent rainfall and plentiful surface water resources, but most countries need to use the water that is stored underground to supplement their needs. Hydrogeologists can help by locating suitable reserves and by assessing how much water it is possible to extract without permanently damaging underground aquifers or surrounding ecosystems.
By looking at the way that groundwater flows, hydrogeologists can also identify when it is at risk from pollution and how we can protect it by careful planning and land-use. Without the knowledge that hydrogeology gives us we have no way of predicting what will happen to our water resources or the future effects on the environment of water extraction.
