Sustainable Groundwater Potential Zoning with Integrating GIS, Remote Sensing, and AHP Model: A Case from North-Central Bangladesh

نویسندگان

چکیده

Groundwater is one of the most valuable natural resources, and dependable source fresh water. For sustainable groundwater management, present study aimed to model potential zones in north–central region Bangladesh using GIS, remote sensing, analytical hierarchy process. The included eight thematic layers: lineament density, geomorphology, soil types, slope, land use/land cover, drainage elevation, rainfall features delineate a zone area. Integration layers was performed through weighted overlay analysis, which assisted delineating zones. This simple systematic method successfully provides satisfactory result concerning delineation resulted map, identifies about 11.51% area as being under very high zone, covering an 504.09 km2. AHP analysis shows that physiographical parameters, such meteorological factors annual rainfall, have greater influence over potentiality. obtained from verified with actual well yield depth data, show significant positive correlation. outcome will help taking effective measures ensure use extraction this region.

Groundwater potentiality through Analytic Hierarchy Process (AHP) using remote sensing and Geographic Information System (GIS)

Nowadays the use of remote sensing and Geographic Information System (GIS) is one of the most powerful cost effective tools to identify and discover the available groundwater resources. In this paper, Lithological Units, Lineaments, Slope, Topography, Drainage density, Vegetation and Isohyets lines have been achieved by stations and through remote sensing and GIS techniques. All layers of diffe...

Using geographic information system (GIS) and remote sensing (RS) in zoning nitrate concentration in the groundwater of Birjand, Iran

Previous studies have shown that the presence of nitrate in drinking water can cause several diseases especially in the infants, such as cancer and blue baby. The Environmental Protection Agency (EPA) has since adopted the 50 mg/l standard as the maximum contaminant level (MCL) for nitrate for regulated public water systems. This study aimed to evaluate the concentration of nitrate in the drink...

Identification of Groundwater Potential Zones in Moalleman, Iran by Remote Sensing and Index Overlay Technique in GIS

Water plays a vital role in the development of activities in an area. The surface water resources are inadequate to fulfill the water demand. Productivity through groundwater is quite high as compared to surface water, but groundwater resources have not yet been properly exploited. Keeping this view, the present study attempts to select and delineate various groundwater potential zones for the ...
