An international scientific society that fosters the transfer of knowledge and practices to sustain global soils. Based in Madison, WI, and founded in 1936, SSSA is the professional home for 6,000+ members dedicated to advancing the field of soil science. It provides information about soils in ...
Water that infiltrates and moves laterally through the upper soil horizons and emerges downslope as seepage before entering a stream.
Industry:Earth science
The estimation or determination of the kinds or amounts of minerals present in a rock or in a soil.
Industry:Earth science
The pH of a solution in equilibrium with soil. It is determined by means of a glass, quinhydrone, or other suitable electrode or indicator at a specified soil-solution ratio in a specified solution, usually distilled water, 0. 01 M CaCl2, or 1 M KCl.
Industry:Earth science
The distribution coefficient, Kd, calculated on the basis of organic carbon content. Koc=Kd /foc where foc is the fraction of organic carbon.
Industry:Earth science
The shallow layer below a streambed that serves as the hydrologic connection between the stream and the groundwater thereby controlling the exchange of water and solutes.
Industry:Earth science
The amount of eroded soil that is delivered to a point in a watershed or transported out of a stream section over a period of time. It includes the contributions of erosion from slopes, channels, and a mass wasting of streambanks minus the sediment deposited before the point of interest.
Industry:Earth science
The rate at which water moves through a unit cross-sectional area of an aquifer of specified thickness under a unit hydraulic gradient. It is equal to the hydraulic conductivity times the thickness of the aquifer.
Industry:Earth science
Those forces caused by electriical attractions and repulsions.
Industry:Earth science
The volume of water flow through a stream or open channel past a point in a given time period.
