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.
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 ...

In India, 2.19 million ha of land has been reported to suffer from waterlogging in irrigation canal commands. Also, 3.47 million ha were reported to be seriously salt-affected, [25] [26] In the Indus Plains in Pakistan, more than 2 million hectares of land are waterlogged. [27]
Canal Lining. Canal lining is the process of reducing seepage loss of irrigation water by adding an impermeable layer to the edges of the trench. Seepage can result in losses of 30 to 50 percent of irrigation water from canals, so adding lining can make irrigation systems more efficient.
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
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.
In geotechnical engineering, watertable control is the practice of controlling the height of the water table by drainage.Its main applications are in agricultural land (to improve the crop yield using agricultural drainage systems) and in cities to manage the extensive underground infrastructure that includes the foundations of large buildings, underground transit systems, and extensive ...
