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.
This may cause the following issues: rising water tables; increased storage of groundwater that may be used for irrigation, municipal, household, and drinking water by pumping from wells; waterlogging and drainage problems in villages, agricultural lands, and along roads - with mostly negative consequences. The increased level of the 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.
The primary man-made cause of salinization is irrigation. River water or groundwater used in irrigation contains salts, which remain in the soil after the water has evaporated . The primary method of controlling soil salinity is to permit 10–20% of the irrigation water to leach the soil, so that it will be drained and discharged through an ...
Employing almost 44% of India's working population, agriculture is one of the most important occupations in India. Consequently, up to 80% of the groundwater in India is used for irrigation. [37] The Indian Agriculture Institute has been promoting the drip irrigation technology to relieve the water scarcity in India for decades. The technology ...
Groundwater is fresh water located in the subsurface pore space of soil and rocks.It is also water that is flowing within aquifers below the water table.Sometimes it is useful to make a distinction between groundwater that is closely associated with surface water, and deep groundwater in an aquifer (called "fossil water" if it infiltrated into the ground millennia ago [8]).
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
The country accounts for 18% of the world's population but has access to only about 4% of the world's water resources. One of the proposed measures to address India's water challenges is the Indian Rivers Interlinking Project. [2] Approximately 80% of India's land area receives rainfall of 750 millimetres (30 in) or more annually.
