The PEG treatment is often paired with vacuum freeze-drying, as the eutectic point of most PEG solutions is below the freezing point of water. This allows the "free" waterlogging water to sublimate in the process of freeze-drying, which minimizes damage to the wood by preventing ice from forming within the cells and expanding, causing more ...
Antique Dutch windmills used to pump water into the embanked river to prevent waterlogging of the lowlands behind them. Waterlogging water is the saturation of soil with water. [1] Soil may be regarded as waterlogged when it is nearly saturated with water much of the time such that its air phase is restricted and anaerobic conditions prevail.
Waterlogging or water logging may refer to: Waterlogging (agriculture), saturation of the soil by groundwater sufficient to prevent or hinder agriculture; Waterlogging (archeology), the exclusion of air from an archeological site by groundwater, preserving artifacts; Underwater logging, the process of harvesting trees that are submerged under water
Drainage system (geomorphology), pattern of natural drains, streams, rivers, etc. Land drainage in the United Kingdom - a legal and operational term in the UK to define a range of functions and responsibilities of drainage boards. Surface runoff, surface runoff of excess rainfall from the land
Such waterlogging preserves perishable artifacts. Thus, in a site which has been waterlogged since the archaeological horizon was deposited, exceptional insight may be obtained by study of artifacts made of leather , wood , textile or similar materials. 75-90% of the archaeological remains at wetland sites are found to be organic material.

Soil salinity is measured as the salt concentration of the soil solution in tems of g/L or electric conductivity (EC) in dS/m. The relation between these two units is about 5/3: y g/L => 5y/3 dS/m. Seawater may have a salt concentration of 30 g/L (3%) and an EC of 50 dS/m.
