Description Ph. d. thesis
Groundwater is under stress in almost all parts of India due to rapid development in agricultural activities, industrialization, urbanization, education, improved sanitation and increase in population. These scarcities of water make groundwater more precious. Faridabad district is also marked by off and on water crisis. All the districts of Faridabad are notified by Central Ground Water Authority (CGWA). Faridabad is situated 32 km. from Delhi, at 28° 25' 16" north latitude and 77° 18' 28" east longitude.
India in general and Faridabad in particular is facing a serious water resource problem and as trends suggest, it is expected to become ‘water stressed’ by 2025 and ‘water scarce’ by 2050 (IDSA, 2010). The Faridabad district is critically reliant on groundwater for both drinking water and non–potable uses. The area comprises both rural and urban area. Better understanding of groundwater flow, identification of recharge and discharge area will ensure sustainability of groundwater resources. ArcGIS (ESRI, USA) is a geographic information system (GIS) for working with maps and geographic information. It is used for creating and using maps; compiling geographic data; analyzing spatial information and managing database in GIS platform. It is used for making DEM, water table contour map interpolation, spatial analysis and raster analysis etc. This has resulted in increased groundwater draft for construction purpose and further leading to decline of water level. The close inspection of four hydrographs reveals that there is distinct pattern in hydrograph behaviour. Ballabhgarh and Bhoapni indicates sharp decline in water level because these monitoring wells lies in urban area. Whereas Kabulpur and Sikri water level is almost constant as these two well fall in rural/agricultural area. In urabn area paved area restricts recharge whereas in rural area return flow from irrigation recharge the aquifer. The groundwater depression is noticeable in Faridabad city due to heavy groundwater withdrawal. The villages like Pali, Mangar, Gothda mohbtabad and Bhankri shows diverging flow indicating it as recharge areas. The hydrogeological setting and assumptions used for analytical solutions are obtained from the hydrogeological study, mean hydraulic conductivity of 17 m/d, specific yield of 0.17 and original water level about 25 meter below ground level. A recharge value of 0.7 m/d, and the recharge basin schematized as a rectangular recharge basin of 100 m by 100 m. At the centre of the basin after 100 days, the height of groundwater mound rises to about 5 m above the present groundwater table. In order to assess the aquifer volume available for recharge GIS based analysis was carried out. Post Monsoon water level is used to estimate unsaturated thickness of aquifer which is available for recharge. Water level more than 3 meter has been considered as maximum water level for recharge above this it will create water logging condition. Groundwater draft has been increased on the assumption that urbanization, increase in population and industrialization will result into increased groundwater draft. Accordingly, groundwater draft has been increased for 2025 and 2050.The results from numerical groundwater modelling shows that the rate of increase if groundwater draft will adversely affect availability of groundwater resources. The western part of the district comprising Bhankri, Bajri, Ghazipur, Nagla Gujran Faridabad, Sirohi, Fatehpur, Sarurpur, Tikri, Dhoj, Paota, Alwalpur, Alampur, and Zakopur, will face severe water shortage in 2025 and 2050. It was concluded from the study that through natural recharge processes only 30 percent of the groundwater is being replenished whereas 70 percent aquifer capacity is still under severe water stress. If the same will continue, by the year 2050 the aquifer storages will about to reach to its minimum storage capacity. Ground water recharge from the treated wastewater from STPs through selected infiltration basins may be one of the strategy to control the declining ground water storage of the aquifers in Faridabad.
