    The result is a 10–15 meter rise in water level, with nutrient rich waters. Várzea forests can be split into two categories: low várzea and high várzea. Low várzea forests can be categorized by lower lying areas where the annual water column has an average height of more than 3 meters, where the period of flooding is greater than 50 days ...

  3. Surface runoff - Wikipedia

    en.wikipedia.org/wiki/Surface_runoff

    Surface runoff often occurs because impervious areas (such as roofs and pavement) do not allow water to soak into the ground. Furthermore, runoff can occur either through natural or human-made processes. [1] Surface runoff is a major component of the water cycle. It is the primary agent of soil erosion by water.

    This is an accepted version of this page This is the latest accepted revision, reviewed on 20 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 ...

  5. Water table - Wikipedia

    en.wikipedia.org/wiki/Water_table

    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.

  6. Wetland - Wikipedia

    en.wikipedia.org/wiki/Wetland

    A simplified definition of wetland is "an area of land that is usually saturated with water". [14] More precisely, wetlands are areas where "water covers the soil, or is present either at or near the surface of the soil all year or for varying periods of time during the year, including during the growing season". [15]

    en.wikipedia.org/wiki/Blood_residue

    Blood residue are the wet and dry remnants of blood, as well the discoloration of surfaces on which blood has been shed. In forensic science, blood residue can help investigators identify weapons, reconstruct a criminal action, and link suspects to the crime. [1] Analysis of blood residue is also an important technique in archeology. [2]

  8. Infiltration (hydrology) - Wikipedia

    en.wikipedia.org/wiki/Infiltration_(hydrology)

    Infiltration is the process by which water on the ground surface enters the soil. It is commonly used in both hydrology and soil sciences. The infiltration capacity is defined as the maximum rate of infiltration. It is most often measured in meters per day but can also be measured in other units of distance over time if necessary. [1] The ...

  9. Groundwater recharge - Wikipedia

    en.wikipedia.org/wiki/Groundwater_recharge

    [7] [8] Groundwater recharge occurs through mineral soils found primarily around the edges of wetlands. [9] The soil under most wetlands is relatively impermeable. A high perimeter to volume ratio, such as in small wetlands, means that the surface area through which water can infiltrate into the groundwater is high. [8]
