“…Hierarchical cluster analysis (HCA) is a significant form of multivariate analysis that has been used to sort different groundwater samples into groups or clusters based on their similarities (Helena et al 2000). Principal component analysis (PCA) is also a useful method to assess the interrelationship among the hydrochemical variables by reducing the number of variables (Chakraborty et al 2021). Initially, Ward's clustering method, followed by extraction method with Eigen value set to 1 based on Kaiser criterion, and finally the Varimax method selected as the rotation factor were followed.…”

“…Correlation matrix (Table 5) was used to demonstrate the interrelationship between the analysed parameters to identify their sources of origin. Correlation analysis is a powerful tool of statistics which explains the interrelation between two parameters and indicates the dependency of each parameter to others to control water quality (Belkhiri and Narany 2015;Chakraborty et al 2021). Correlation coefficient result shows that there was a moderately positive correlation between KR and PI (r = 0.61).…”

Groundwater alone comprises nearly about 80% of the available water for irrigation purpose in Murshidabad and this usage of groundwater for irrigation is yet to increase further in the upcoming years. The present study was carried out to access the groundwater’s suitability for different agricultural purposes in and around Sagardighi block of Murshidabad district, West Bengal, India. Groundwater samples from thirty three different locations around Sagardighi were collected and then tested in the laboratory for various physical as well as chemical parameters such as electrical conductivity (EC), total dissolved solids (TDS), pH, some major cations (Ca2+, Mg2+, Na+, K+, Fe2+) and some anions (CO32−, HCO3−, Cl−). To further delineate the suitable groundwater zones for irrigation practices, the irrigation water quality parameters such as sodium adsorption ratio (SAR), sodium percentage (Na%), magnesium adsorption ratio (MAR), permeability index (PI), residual sodium carbonate (RSC), Kelly’s ratio (KR) were also calculated. Results show that most of the water samples had low to medium salinity, while only a very few of the samples show high salinity. Piper trilinear plot reveals that the water is primarily of Ca–Mg–HCO3− facies type. The SAR value of majority of the water samples in the study area are less than 10, which is within safe limits. RSC values indicate that the carbonate content is extremely low in the groundwater of the study area. Overall, the results indicate that majority of the samples are fit to be used for irrigational purpose. The findings of this study would help decision-makers in developing irrigation suitability planning and groundwater resource management in the future.

“…Figure 3 shows that rainfall varies significantly, with a minimum of 1258.06 mm and a maximum of 1398.45 mm 4. Higher rainfall in the study region ranges from 1362.67-1398.45 mm and assigned a higher rank (9), whereas low rain-fed regions 1258.06-1290.54 mm were assigned a lower rank (5) shown in Table 5.…”

Due to the indiscriminate use of limited water sources, the requirement for groundwater evaluation in India expanded substantially. Population growth and unequal distribution, poor irrigation systems, rapid urbanization/ industrialization, large-scale deforestation, droughts, and inefficient land use practises contribute to groundwater depletion.As a result, the need for water for agriculture, domestic, and industry soars. The study identifies viable zones in Visakhapatnam's emerging metropolitan metropolis by utilising the Analytical Hierarchy Process (AHP) approach with remote sensing data in ArcGIS software. Thematic layers were created by taking remote sensing data into consideration (drainage density, soil, lineament density, land use land cover, geomorphology, rainfall, slope, and geology). The method is employed to determine the weights of distinct thematic layers by obtaining the normalised weight from a pairwise matrix.To emphasize the groundwater potential zones and create a map with different zones specified, the weights and ranks extrapolated from the AHP approach have been made available in the weighted index overlay analysis tool in ArcGIS.Groundwater availability and recharge are significantly high in the good zone of the present study's four classifications of good, moderate, low, and very low. The groundwater status, potential locations for water extraction, and best practises for groundwater recharging may all be determined with the use of the acquired information from the indication map.

“…Regionally, this is a part of eastern Indian peninsular shield and Chota Nagpur Gneissic complex (CGC). This region consists with granitic rock and metasediments of Precambrian age which is considered as a basement rock or the fundamental rock of this area and the whole region is situated in the northern part of Singhbhum craton (Dunn and Dey 1942;Chakraborty et al 2021).…”

Scarcity of groundwater is a severe problem in this region due to over exploitation of groundwater from unconfined hard rock aquifers. The main objectives of this study are to analyse the spatiotemporal variability and fluctuation of groundwater table and to predict the location of groundwater depression pockets. Total 21 consecutive years (1996–2017) groundwater monitoring well data (pre- and post-monsoon) have been collected from CGWB, Government of India. The nonparametric Mann–Kendall trend analysis and standardized precipitation index (SPI) have been applied to detect the trend of groundwater level and rainfall variability, respectively. Exponential smoothing has also been fitted for future prediction. The pre- and post-monsoon results (1996–2017) showed that around 77% (22 stations) and 78% (23) monitoring stations were indicating declining trend of groundwater table at the rate of −0.006 to −0.205 m/year and −0.005 to −0.192 m/year, respectively. Similarly, future (2040) groundwater depression result predicted that around 75% (21) stations, the groundwater table will be depleted above 5 m during pre-monsoon while about 53% (16 stations) monitoring wells, the groundwater table will be fallen above 5 m during post-monsoon. Consequently, around 52% (15) and 50% (14) stations are being faced groundwater drought in the recurrent interval of above 2 years during pre-monsoon and post-monsoon, respectively. Driving factors of water table depletion are huge withdrawal of groundwater for dry farming and reduction of recharge areas due to rapid land use modification. The uniqueness of this study exhibits the nature of declining trend of groundwater table and identification of depression pockets.
