“…where X ij is normalized pair-wise matrix value at i th row and j th column, C ij is the value assigned to each criteria at i th row and j th column and L ij is the total values in each column of the pair-wise matrix. Subsequently, a standard weight was calculated for variable i by dividing each normalized pairwise matrix elements by criterion number (N) (Equation (5)) [64,65].…”

Mapping groundwater recharge zones (GWRZs) is essential for planning artificial recharge programs to mitigate groundwater decline and saltwater intrusion into coastal aquifers. We applied two multi-criteria decision-making approaches, namely the analytical hierarchy process (AHP) and the multi-influencing factors (MIF), to map GWRZs in the Korba aquifer in northeastern Tunisia. GWRZ results from the AHP indicate that the majority (69%) of the area can be classified as very good and good for groundwater recharge. The MIF results suggest larger (80.7%) very good and good GWRZs. The GWRZ maps improve groundwater balance calculations by providing estimates of recharge-precipitation ratios to quantify percolation. Lithology, land use/cover and slope were the most sensitive parameters followed by geomorphology, lineament density, rainfall, drainage density and soil type. The AHP approach produced relatively more accurate results than the MIF technique based on correlation of the obtained GWRZs with groundwater well discharge data from 20 wells across the study area. The accuracy of the approaches ultimately depends on the classification criteria, mean rating score and weights assigned to the thematic layers. Nonetheless, the GWRZ maps suggest that there is ample opportunity to implement aquifer recharge programs to reduce groundwater stress in the Korba aquifer.

“…Groundwater use is continuously increasing. These increasing demands usually result in overexploitation, putting a pressure on the limited supply of freshwater (Jahan et al, 2019). Furthermore, groundwater problems have worsened, particularly in the tropical and subtropical zones, as a result of unregulated irrigation practices, high population density and climate change.…”

PurposeThe present study aims to construct ensemble machine learning (EML) algorithms for groundwater potentiality mapping (GPM) in the Teesta River basin of Bangladesh, including random forest (RF) and random subspace (RSS).Design/methodology/approachThe RF and RSS models have been implemented for integrating 14 selected groundwater condition parametres with groundwater inventories for generating GPMs. The GPM were then validated using the empirical and bionormal receiver operating characteristics (ROC) curve.FindingsThe very high (831–1200 km2) and high groundwater potential areas (521–680 km2) were predicted using EML algorithms. The RSS (AUC-0.892) model outperformed RF model based on ROC's area under curve (AUC).Originality/valueTwo new EML models have been constructed for GPM. These findings will aid in proposing sustainable water resource management plans.

“…Groundwater is thought to provide almost one-third of the world's fresh water where 36, 42, and 27 % is utilized for domestic, farming, and industrial applications respectively (Taylor et al, 2013). Bangladesh is located in lower riparian country in the Ganges-Brahmaputra-Meghna (GBM) delta system in South Asia, and the second most vulnerable country in the world from socio-economic standpoint (Jahan et al, 2019). Due to significant increase in population, the global demand for fresh water is rising.…”

The southwestern coastal zone in Bangladesh faces freshwater scarcity as aquifers are more vulnerable to seawater intrusion resulting increase its salinity level. But here fresh groundwater resource badly needed for drinking, agricultural, and industrial uses to sustain livelihood. The present study has made attempt to demarked available fresh groundwater zones in Khulna district in the southwestern coastal zone using multi-criteria decision making (MCDM) tool and analytical hierarchy process (AHP) with remote sensing (RS) and GIS approach. To delineate fresh groundwater potential zones, twelve thematic parameters such as groundwater salinity, groundwater electrical conductivity, groundwater chloride, rainfall, concentration of soil salinity, land slope, geomorphology, surface geology, land use and land cover, drainage density, lineament density, topographic wetness index have processed utilizing ArcGIS overlay analytic tool. Accordingly, the area has classified as very good [18 km2 (0.52%)] - safe for drinking and agriculture; good [858 km2 (25%)] - useful only for agriculture purposes; low [354 km2 (11%) - use for irrigation of certain high salinity tolerate crops having high risk for human consumption; and very low [2148 km2 (64%)] - unsuitable to use due to seawater intrusion or high salinity of the total area. The salinity-prone zone covers 75% of the total area requires especial management approach. Finally, findings will aid in identification of fresh groundwater potential zone for human consumption and agriculture in salinity effected coastal zone of the country to ensure sustainable groundwater use and extraction in this coastal areas, and findings of the present study can be utilized as a guide for addressing groundwater issues for this region.
