“…Penelitian ini diharapkan dapat memperoleh gambaran geologi bawah permukaan, terutama susunan litologi dalam kaitannya dengan fungsi batuan yang bersangkutan sebagai akuifer dari airtanah, sehingga dapat mengetahui data kondisi hidrogeologinya (gambar 1). Untuk melihat kondisi geologi hidrogeologinya diperlukan pendugaan bawah permukaan hal ini dapat dilakukan dengan pendekatan metode geolistrik (Oni et al, 2019;Nair et al, 2019). Hasil dari pengukuran geolistrik ini diharapkan dapat menginterpretasikan kondisi bawah permukaan litologi batupasir daerah telitian sehingga dapat menghitung potensi akuifernya (Issar & Levanon, 2010).…”

The purpose of this study was to determine the potential of groundwater in Alasombo, Weru District, Sukoharjo Regency, Indonesia. The investigation has been carried out using geophysical methods that are integrated with surface geological data to obtain an interpretation of the hydrogeological control of the aquifer. The lithology of the aquifer is dominated by sandstone which controls its role as 2 types of aquifers, namely unconfined aquifers or free aquifers and semi-confined aquifers or semi-free aquifers. The geoelectrical section shows that the groundwater-carrying layer that functions as an aquifer is the sandstone layer in the second layer and sandstone in the base layer. As an artesian aquifer or a confined aquifer, sandstone aquifers have a water volume between 31.5 to 260 m3/day, in a northwest-southeast direction. In terms of the quality of the conductivity value of water in the field, below 1500 µs/cm is freshwater type groundwater that can be recommended as a source of clean water.

For the humanity to the whole and all the creatures of this world, the underground water is the greatest resource to rely upon that highly forms an indispensable factor toward augmented livelihood. In spite of the lack of detailed knowledge, global warming is found to profoundly influence underground water resources through changes in underground water recharge. Prediction of the underground water under a changing climate is essential to living beings. In this article, underground water prediction using optimal deep neural networks (optimal DNN) has been attempted. Initially, the features of temperature and rainfall among the input data have been selected and after which, the chosen data have been fed to the DNN to predict the underground water. In DNN, weight parameters are optimally selected with the help of fish swarm optimization (FSO). The implementation has been done on MATLAB. The simulation results found that the proposed FSO-DNN prediction approach outperforms the existing prediction approaches by 78.9% accuracy, 83% sensitivity, 88% specificity, 95.8% positive predictive values, 52.3% negative predictive values, and 95.8% F-measure.

“…In recent years, around the world many researchers have extensively used Vertical Electrical Sounding for the assessment of groundwater potential zone [21] , [22] , [23] , [24] , [25] . Consequently, much research has also been carried out in various parts of India and the state of Tamil Nadu by various researchers [26] , [27] , [28] , [29] , [30] . This present study mainly focuses on deciphering the groundwater potential zone in the Karumeniyar river basin employing geophysical vertical electrical sounding (VES).…”

In the Karumeniyar river basin, the groundwater demand increases for irrigation, industrial and larger per capita needs, and the recent year's groundwater table is drastically falling due to both natural and anthropogenic activities. In this context, a study on geophysical vertical electrical sounding (VES) using Schlumberger configuration has been carried out across 72 locations in the Karumeniyar river basin to demarcate the subsurface geoelectrical parameters and to identify the groundwater potential zone along with aquifer protective capacity. The acquired data were inverted using the 1D (resistivity variation with respect to depth) inversion approach IPI2Win demonstrated the presence of three to six subsurface geoelectrical layers in the study area with H type sounding curve being dominant. Furthermore, the deciphered result from VES is cross-validated with lithology data of four wells in the study area. Based on the interpreted results the parameters such as longitudinal conductance, overburden thickness, reflection coefficient and basement resistivity were calculated. It revealed that 36 VES location signifies good to moderate aquifer protective capacity. According to the reflection coefficient value and overburden thickness, the basin was divided into four distinct groundwater potential zones as high (42%), medium (38%), low (15%) and very low (5%). The inverse Distance Weighting (IDW) interpolation method is adopted to generate the spatial distribution maps in ArcGIS environment. The findings of the present study provide the vital geo-database for groundwater potential zones in the Karumeniyar river basin and have important implications for designing, intendance and management of sustainable groundwater resources. • Vertical Electrical Sounding method is a noninvasive, low cost and effective method for locating groundwater potential zone. • It measures the vertical wise variation of subsurface resistivity distribution based on surface measurement. • This technique provides a quantitative evaluation of different subsurface layers.
