Assessment of groundwater potential zones in Allahabad district by using remote sensing & GIS techniques
The current study was conducted to identify potential ground water zone in Allahabad district using remotely sensed data and GIS techniques. In the current study, remotely sensed land use and DEM data were utilized to assess ground water potential zones. The land use data was derived by USGS (United States Geological Survey) using SPOT 4 satellite images. DEM (Digital Elevation Model) data used in current study also obtained from USGS. The presence of ground water in a given area is a result of many hydro geological factors such as land use pattern and slope. The assessment of ground water potential zone is done by taking in account an impact of land use and slope on ground water after assigning ranks and weightage to these factors. Various land use classes were given weight and ranks according to their potential towards ground water. Similarly slope of study area was weighted and ranked according to its impact on ground water potential for e.g.- areas with steep slopes were weighted and rank least because the surface water would stand long enough to get infiltrated and subsurface water in these areas will tend to less slope or to the level areas.
It is found that the ground water potential zones information analyzed for Allahabad district can be used for effective utility of ground water for domestic and other purposes. It is also useful for identification of suitable wells location for extraction of water and it’s a convenient and time saving method as compare to field methods.
The ground water potential zones map of study area were classified into four zones viz. excellent, good, moderate and poor zones gave a more realistic view to understand potential ground water areas and can be used for groundwater development & management.
Overall, this study focused on the assessment of groundwater potential zones in Allahabad district for getting the holistic view on planning, utilization, administration and management of groundwater resources.
