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.
Over-irrigation can cause deep drainage from rising water tables that can lead to problems of irrigation salinity requiring watertable control by some form of subsurface land drainage. However, if the soil is under-irrigated, it gives poor soil salinity control , which leads to increased soil salinity with the consequent buildup of toxic salts ...
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.
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.
Water pollution is a major environmental issue in India. The largest source of water pollution in India is untreated sewage. [1] Other sources of pollution include agricultural runoff and unregulated small-scale industry. Most rivers, lakes and surface water in India are polluted due to industries, untreated sewage and solid wastes.
As per the Millennium Ecosystem Assessment of 2005, land degradation is in defined as "the reduction or loss of the biological or economic productivity of drylands". [6] A similar definition states that land degradation is the "degradation, impoverishment and long-term loss of ecosystem services".
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.
Stream ripping (also called stream recording) is the process of saving data streams to a file. The process is sometimes referred to as destreaming.. Stream ripping is most often referred in the context of saving audio or video from streaming media websites and services such as YouTube outside of the officially-provided means of offline playback (if any) using unsanctioned software and tools.
