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

Authors

Abstract:

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 different classes were initialized through hierarchical analysis to potential areas of groundwater and after modeling in GIS Environment, Mahdishahr zone was classified according to the potential groundwater basins. The results show that in the 7 reviewed criteria by the expertise and Analytical Hierarchy Process, geological criterion and lineaments with the relative importance of 0.33 and 0.22, respectively, have greatest importance and priority for potentiality of groundwater in the region. Also in the studied area, Quaternary Alluvium consisted of old and new terrace and river sediments have the highest relative importance and desirability and terrace resources and the elevated old and low height new Foothill Alluvial fans are considered as good potential areas of groundwater. Shemshak Sandstone formations and Barut with a high density lineaments and Tizkouh formation with the thick layers of limestone and Barut are also good areas for groundwater

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...

Survey Fertility Mapping of the Maghan Area Using Global Information System (GIS) and Analytic Hierarchy Process (AHP)

In the face of rapid growth of the population and the need for food production sectors, one of the ways to achieve this is to increase the production per unit area. In modern agriculture, the preparation of soil fertility map seems to be necessary to plan for appropriate use of fertilizers for crops. This study was conducted to prepare a distinct map for evaluating the soil fertility according ...

Land cover land use mapping and change detection analysis using geographic information system and remote sensing

Land cover/land use categories are relevant components in land management. Understanding how land cover/land use change over time is necessary to assess the consequences of humans and natural stressors on the earth’s environment and resources. The aim of the study was to map and monitor the spatial and temporal change in land cover/land use for the periods of 1977, 1991 and 2016 and to predict ...

Inland wetlands mapping and vulnerability assessment using an integrated geographic information system and remote sensing techniques

The understanding of inland wetlands’ distribution and their level of vulnerability is important to enhance management and conservation efforts. The aim of the study was to map inland wetlands and assess their distribution pattern and vulnerability to natural and human disturbances such as climate change (temperature increase) and human activities by the year 2080. Inland wetland types i.e. for...

A geographic information system for gas power plant location using analytical hierarchy process and fuzzy logic

This study recommends a GIS-based (Geographic Information Systems) and multi-criteria evaluation for site selection of gas power plant in Natanz City of Iran. The multi-criteria decision framework integrates legal requirements and physical constraints related to environmental and economic concerns. It also builds a hierarchy model for gas power plant suitability. The methodologies used for site...
