2. Groundwater - Wikipedia

   en.wikipedia.org/wiki/Groundwater

   This is an accepted version of this page This is the latest accepted revision, reviewed on 15 January 2025. Water located beneath the ground surface An illustration showing groundwater in aquifers (in blue) (1, 5 and 6) below the water table (4), and three different wells (7, 8 and 9) dug to reach it. Groundwater is the water present beneath Earth's surface in rock and soil pore spaces and in ...

3. Submarine groundwater discharge - Wikipedia

   en.wikipedia.org/wiki/Submarine_groundwater...

   Both types of water can circulate in marine sediments due to tidal pumping, waves, bottom currents or density driven transport processes. Meteoric freshwaters can discharge along confined and unconfined aquifers into the sea or the oppositional process of seawater intruding into groundwater charged aquifers can take place. [ 1 ]

4. Pore water pressure - Wikipedia

   en.wikipedia.org/wiki/Pore_water_pressure

   If the water table is at depth d w in fine-grained soils, then the pore pressure at the ground surface is: [4] =, where: p g is the unsaturated pore water pressure (Pa) at ground level, g w is the unit weight of water (kN/m 3), = / d w is the depth of the water table (m),

5. Watertable control - Wikipedia

   en.wikipedia.org/wiki/Watertable_control

   In geotechnical engineering, watertable control is the practice of controlling the height of the water table by drainage.Its main applications are in agricultural land (to improve the crop yield using agricultural drainage systems) and in cities to manage the extensive underground infrastructure that includes the foundations of large buildings, underground transit systems, and extensive ...

6. Water table - Wikipedia

   en.wikipedia.org/wiki/Water_table

   The slope of the water table is known as the “hydraulic gradient”, which depends on the rate at which water is added to and removed from the aquifer and the permeability of the material. The water table does not always mimic the topography due to variations in the underlying geological structure (e.g., folded, faulted, fractured bedrock).
