“…Around the world, different methods have been used in delineating GWPZs such as integration of remote sensing and GIS with resistivity data [77], influence factor (IF) [47,51,66], statistical methods [78,79], groundwater modeling [80], and analytical hierarchy process (AHP) [63,74,81]. These methods have been proven as reliable and effective, and have been used by many researchers.…”

Rapid population growth has raised the groundwater resources demand for socio-economic development in the Shatt Al-Arab basin. The sustainable management of groundwater resources requires precise quantitative evaluation, which can be achieved by applying scientific principles and modern techniques. An integrated concept has been used in the current study to identify the groundwater potential zones (GWPZs) in the Shatt Al-Arab basin using remote sensing (RS), geographic information system (GIS), and analytic hierarchy process (AHP). For this purpose, nine groundwater occurrence and movement controlling parameters (i.e., lithology, rainfall, geomorphology, slope, drainage density, soil, land use/land cover, distance to river, and lineament density) were prepared and transformed into raster data using ArcGIS software. These nine parameters (thematic layers) were allocated weights proportional to their importance. Furthermore, the hierarchical ranking was conducted using a pairwise comparison matrix of the AHP in order to estimate the final normalized weights of these layers. We used the overlay weighted sum technique to integrate the layers for the creation of the GWPZs map of the study area. The map has been categorized into five zones (viz., very good, good, moderate, poor, and very poor) representing 4, 51, 35, 9, and 1% of the study area, respectively. Finally, for assessing the effectiveness of the model, the GWPZs map was validated using depth to groundwater data for 99 wells distributed over the basin. The validation results confirm that the applied approach provides significantly solid results that can help in perspective planning and sustainable utilization of the groundwater resources in this water-stressed region.

“…At this stage, a number of questionnaires were distributed among water resources and water engineering experts, the main question of which is to introduce the effective parameters in groundwater potential. By summarizing these questionnaires, the effective factors are: ground slope, direction of ground slope, vegetation density, type, and grading of soil, rate of annual rainfall [20]. These selected factors should be evaluated separately.…”

“…It should be noted that this was done by special forms that were prepared for this research. After completing the evaluation forms for the layers, weights are assigned to each layer using Analytic Hierarchy Process (AHP) [20][21][22][23].…”

Iran is currently experiencing serious water-related issues. Frequent droughts combined with over-abstraction of surface and groundwater through a large network of hydraulic infrastructure and deep wells have brought the country's water situation to a critical level. Symptoms of this condition include drying of lakes, rivers and wetlands, declining groundwater levels, land subsidence, water quality degradation, soil erosion, desertification and dust storms. For example, the agricultural sector of Garmsar and Aradan counties has been damaged due to the lack of a coherent and codified plan, so that now, in addition to the problems of soil erosion and water salinity, farmers' motivation to work in this productive sector has decreased. Using experts' views in the field of water engineering and resources, the main factors affecting feeding of the Garmsar groundwater aquifers were identified and each one was classified and evaluated, then using a two-by-two comparison method known as the AHP, each of these factors was weighted and by means of the Arc GIS software, the identified factors were implemented in layers on the digital map of the Garmsar region. The overlap of the obtained layers of each factor in each of the mentioned methods leads to reaching the potential area of the region, i.e. The area where the probability of precipitation is higher and the risk of flooding is lower, and comparing the obtained area with the catchment area indicates the accuracy of the calculations. Now, by identifying the potential groundwater area as well as the flood prone areas, it is possible to propose solutions and suggestions to prevent wastage of water flow or reduce its effects, one of the advantages of which is the filling of groundwater aquifers.

“…Lineaments are as the linear or curvilinear surface expression of structural features in underlying bedrock, including faults, cleavages, fractures, and other surfaces of discontinuity (O’Leary et al 1976 ; Yeh et al 2008 ), that can regulate groundwater accumulation (Roy et al 2021 ). Because the existence of lineaments generally implies a permeable zone, the density of lineaments in each region can immediately disclose the groundwater potential (Saranya and Saravanan 2020 ). Lattman and Parizek ( 1964 ) were the first to adopt a lineaments map to exploit groundwater.…”

Ground water is a precious natural resource in every aspect of human life from natural to artificial environment. Ground water is an indicator of regional development by improving the economic domain through intensive agricultural practices, and aesthetic value through sufficient ground water supply as drinking water, fertile soil, and healthy vegetation. However, ground water availability and associated human perceptions were the main themes of the present study. In this study, both primary and secondary data were incorporated to understand the human adaptation behaviour in drought-prone areas of the fringe of Chhotanagpur plateau region (Bankura-I and II blocks) to ground water storage. GWPZ mapping is a very important exposure to knowing the ground reality. So, the MCDM-AHP method has been developed based on the eight dominant conditioning factors viz. geomorphology, lithology, lineament density, soil, drainage density, LULC, average slope, and slope aspect using GIS analytics with field expertise. The output result was validated with comparing 105 inventory stations where 0.850 AUC value was good for accepting the GWPZ model. As a result, a major portion of the study area is dominated by poor to moderate possibilities of ground water level (ground water level drops 1–2 m during the pre-monsoon) due to Proterozoic granite gneiss formation over the study area. With comparing demographic status, it was not favourable for a healthy lifestyle. Agriculture dominated rural environment of Bankura-I and II blocks is far away from the modern digital environment that is why ground water has played a very crucial role in the field of development. Moreover, to build up a good level of ground water recharge zone through rainfall harvesting, and sustainable land use planning will be the best management practices. So, availability of ground water should be a positive sign of development in the field of the economic sector and sustainable human society.
