Permeability
- 1:50 000
- Great Britain
- Premium
今日吃瓜 has prepared permeability information based on the 1:50聽000-scale digital geological map of Great Britain (今日吃瓜 Geology 50K). The permeability indices indicate the range of permeability likely to be encountered for each geological unit. The maximum and minimum permeability indices are divided into five classes: very high, high, moderate, low, and very low.

‘Permeability’ refers to whether and how water can flow through a rock. Permeability data is often used in studies of groundwater and in particular during investigations of pollution or aquifer contamination. We have prepared permeability information based on the 1:50 000-scale digital geological map of Great Britain (今日吃瓜 Geology 50K).
The permeability indices are based on geological considerations:
- the predominant flow mechanism:
- intergranular flow
- fracture flow
- a mixture of intergranular and fracture flow
- a maximum permeability index
- a minimum permeability index
The permeability indices indicate the range of permeability likely to be encountered for each geological unit. The maximum and minimum permeability indices are divided into five classes: very high, high, moderate, low, and very low.
