  2. Soil liquefaction - Wikipedia

    en.wikipedia.org/wiki/Soil_liquefaction

    If the soil is saturated by water, a condition that often exists when the soil is below the water table or sea level, then water fills the gaps between soil grains ('pore spaces'). In response to soil compressing, the pore water pressure increases and the water attempts to flow out from the soil to zones of low pressure (usually upward towards ...

  3. Dispersion (geology) - Wikipedia

    en.wikipedia.org/wiki/Dispersion_(geology)

    In soil layers where clays are saturated with sodium ions ("sodic soils"), soil can break down very easily into fine particles and wash away. This can lead to a variety of soil and water quality problems, including: large soil losses by gully erosion and tunnel erosion; Soil structural degradation, clogging and sealing where dispersed particles ...

  4. Groundwater - Wikipedia

    en.wikipedia.org/wiki/Groundwater

    Groundwater is fresh water located in the subsurface pore space of soil and rocks.It is also water that is flowing within aquifers below the water table.Sometimes it is useful to make a distinction between groundwater that is closely associated with surface water, and deep groundwater in an aquifer (called "fossil water" if it infiltrated into the ground millennia ago [8]).

  5. Groundwater recharge - Wikipedia

    en.wikipedia.org/wiki/Groundwater_recharge

    Deeper ponding exerts pressure that forces water into the ground faster. Faster flow dislodges contaminants otherwise adsorbed on soil and carries them along. This can carry pollution directly to the raised water table below and into the groundwater supply. Thus, the quality of water collecting in infiltration basins is of special concern.

  6. Soil sloughing - Wikipedia

    en.wikipedia.org/wiki/Soil_sloughing

    Due to precipitation, seasonal changes in Water content can lead to soil sloughing. [7] Soil sloughing is also an indicator of active soil movement and frequently requires action to reduce or prevent bank and slope failure. Soil water content is highly related to the mass erosion that leads to soil sloughing or even slopes failure. [7]

    The research team traveled to the lake in the summers of 2019 and 2020, and with the help of ground-penetrating radar, discovered that Lake Enigma—true to its name—contained a secret: liquid ...

  8. Soil water (retention) - Wikipedia

    en.wikipedia.org/wiki/Soil_water_(retention)

    Pores (the spaces that exist between soil particles) provide for the passage and/or retention of gasses and moisture within the soil profile.The soil's ability to retain water is strongly related to particle size; water molecules hold more tightly to the fine particles of a clay soil than to coarser particles of a sandy soil, so clays generally retain more water. [2]

    A major water main break in the Bronx caused severe flooding and left cars submerged in feet of water on Monday night, FDNY officials said. The main burst around 7:30 p.m. on Webster Avenue ...
