groundwater table information

Water table - Wikipedia

Form. The water table may vary due to seasonal changes such as precipitation and evapotranspiration.In undeveloped regions with permeable soils that receive sufficient amounts of precipitation, the water table typically slopes toward rivers that act to drain the groundwater away and release the pressure in the aquifer.

Infiltration systems: groundwater risk assessments - GOV.UK

How to assess the risks to groundwater for treated effluent discharges.

Groundwater-issues-SUDS

The infiltration rate must be considered in conjunction with the water table elevation which for most schemes should be at least 1 m below the base of the SuDS scheme. This unsaturated thickness is necessary to ensure that there is space for a local rise in groundwater that may result from stormwater infiltration.

FAQ groundwater flooding

Groundwater flooding is most likely to occur in low-lying areas underlain by permeable rocks (aquifers). These may be extensive, regional aquifers, such as Chalk or sandstone, or may be localised sands or river gravels in valley bottoms underlain by less permeable rocks.
