High groundwater elevation definition

High groundwater elevation means the higher of either the elevation to which the soil is saturated when observed as a free water surface, or the elevation to which the soil has been seasonally or periodically saturated as indicated by the highest elevation of redoximorphic features in the soil profile.

High groundwater elevation means the highest elevation to which subsurface water rises. This may by evidenced by the actual presence of water during wet periods of the year, or by soil mottling during drier periods. "Mottling" is a mixture or variation of soil colors. In soils with restricted internal drainage, gray, yellow, red, and brown colors are intermingled giving a multi-colored effect.

High groundwater elevation means the uppermost part of the soil or underlying material wholly saturated with water. The term includes perched and apparent conditions that are seasonally saturated for a time period in excess of two weeks, or permanently saturated.

More Definitions of High groundwater elevation

High groundwater elevation means the highest elevation to which subsurface water rises.
Sample 1
High groundwater elevation means the elevation of the groundwater at the upper surface of the zone of saturation as may occur during wettest periods of the year as observed as a free water surface in an unlined hole or has been saturated as may be indicated by mottling (soil color patterns), whichever of the two levels is higher. Highest groundwater elevation shall be determined by using generally accepted soils evaluation practices and shall be consistent with practices used by the U.S. Soil Conservation Service.
