The major archaeological problem with waterlogged finds, particularly wood, is that they deteriorate rapidly when they are uncovered, beginning to dry and crack almost at once. They therefore need to be kept wet until treated in a laboratory. Conservation measures explain why wet archaeology costs around four times as much as dry archaeology.
Waterlogged wood is a wooden object that has been submerged or partially submerged in water and has affected the original intended purpose or look of the object. Waterlogged wood objects can also include wood found within moist soil from archaeological sites, underwater archaeology, maritime debris, or damaged wood objects.
A wet earthflow occurs where the loss of strength of a section of bank due to saturation increases the weight of the bank and decreases the banks material strength so that the soil flows as a viscous liquid. [2] This type of failure usually occurs on low angle banks and the affected material flows down the bank to form lobes of material at the ...
Podzolization (or Podsolization [9]) is a complex soil formation process by which dissolved organic matter and ions of iron and aluminium, released through weathering of various minerals, form organo-mineral complexes and are moved from the upper parts of the soil profile and deposit in the deeper parts of soil.
The national sampling and identification manual provides: background information on acid sulfate soil formation and disturbance processes and environmental impacts; the minimum requirements of a desktop assessment and site inspection; and a guide to sampling and field testing. Key features of the national laboratory methods manual are:
A hydric soil is defined by federal law [4] to mean "soil that, in its undrained condition, is saturated, flooded, or ponded long enough during a growing season to develop an anaerobic condition that supports the growth and regeneration of hydrophytic vegetation".
Wet conditions were the main talking point during the US women’s soccer team’s penalty shootout victory over Canada in the W Gold Cup semifinals on Wednesday.. The game was played on a heavily ...
It is prone to problems. The soil is very light, so windbreaks are necessary to protect these fields in dry weather. It also can catch fire and burn underground for months. Oxidation also removes a portion of the soil each year, making it progressively shallower.
