aquifercharacterisatie

Aquifer characterisation is the process of determining the physical and chemical properties of an aquifer, which is an underground layer of water-bearing permeable rock or unconsolidated materials. This process is crucial for understanding the potential of an aquifer to supply water and for managing groundwater resources sustainably. Aquifer characterisation involves various methods, including geological surveys, geophysical investigations, and hydrogeological studies.

Geological surveys provide information about the type of rock or sediment, its structure, and the presence of fractures or faults that can affect water flow. Geophysical methods, such as electrical resistivity tomography and seismic refraction, help to map the subsurface and identify the boundaries and properties of the aquifer. Hydrogeological studies involve the collection and analysis of water samples to determine the chemical composition and the presence of contaminants. Additionally, pumping tests are conducted to assess the aquifer's hydraulic properties, such as transmissivity and storage coefficient.

The results of aquifer characterisation are used to create hydrogeological models that simulate groundwater flow and contaminant transport. These models help in predicting the behavior of the aquifer under different scenarios and in designing effective groundwater management strategies. Aquifer characterisation is essential for ensuring the sustainable use of groundwater resources, protecting water quality, and mitigating the impacts of climate change on water availability.
