An aquifer cross-section. This diagram shows two aquifers with one aquitard (a confining or impermeable layer) between them, surrounded by the bedrock aquiclude, which is in contact with a gaining stream (typical in humid regions).
This diagram shows two aquifers with one aquitard (a confining or impermeable layer) between them, surrounded by the bedrock aquiclude, which is in contact with a gaining stream (typical in humid regions). The water table and unsaturated zone are also illustrated. Aquifers occur from near-surface to deeper than 9,000 metres (30,000 ft). [2]
aquitard A bed or layer of rock that slows the conveyance of water from an aquifer due to its low permeability or low hydraulic conductivity. archipelago A collection of islands in a sea. arête A sharp, narrow mountain ridge, often resulting from the erosive activity of alpine glaciers flowing in adjacent valleys. [2] arroyo. Also wash.
