机译：An approximate projection of availability of the fresh groundwater resources in the South West district of NCT Delhi, India: a case study
The future availability and sustainability of fresh groundwater resources in the South West district of the national capital territory (NCT) Delhi, India, have been projected. Due to a rapid decline in groundwater level and quality, the district has been required by the Government of India to regulate development of groundwater resources. Shallow groundwater is mostly saline and water resources in the area are limited. The methodology applied here involves microzonation of the district in terms of thickness of fresh groundwater and then quantification of present and future availability of freshwater in different freshwater zones, including tentative timescales. The calculation method has been aided by data on historic trends in water level at representative groundwater monitoring stations, located either in fresh groundwater zones or near to them. It is estimated that the presently available 481 million m(3) of resources will be reduced to 374 million m(3) by year 2007 and to 303 million m(3) by the year 2012, and by 3 the year 2022 the district will have only 176 million m of available fresh groundwater resources.
