“…The Nubian Aquifer System (NAS) is a significant transboundary aquifer that serves as a crucial groundwater reservoir. It covers the dry areas of Egypt, Libya, Chad, and Sudan, making it one of the largest in the world (Sultan Araffa et al, 2009;Mohamed et al, 2017;Mohamed, 2019;Mohammed et al, 2023c). The aquifers in question are of great importance in maintaining water resources and supporting the lifestyles of people in the nations mentioned (Voss and Soliman, 2014).…”

The recent research aims to investigate the petrophysical and hydrogeological parameters of the Nubian aquifer system (NAS) in Northern Khartoum State, Sudan, using integrated geophysical methods, including surface electrical resistivity and geophysical well-logging. The Nubian aquifer is a transboundary regional aquifer that covers vast areas in Sudan, Egypt, Libya and Chad. The well-logs, including self-potential (SP), natural gamma ray (GR), and long normal resistivity (RS), are integrated with Vertical Electrical Sounding (VES) measurements to delineate the hydrostratigraphical units. As a result, two aquifers are detected. An upper aquifer comprises coarse sand with an average thickness of 50 m and a lower aquifer of sandstone with more than 200 m thickness. For a thorough evaluation of the aquifers, in the first stage, the petrophysical and hydrogeological parameters, including formation factor, total and effective porosity, shale volume, hydraulic conductivity, and transmissivity, are measured solely from geophysical well-logs. In the second step, the results of geophysical well logs are combined with VES and pumping test data to detect the spatial variation of the measured parameters over the study area. As a result, the hydraulic conductivity of the Nubian aquifers ranged from 1.9 to 7.8 m/day, while the transmissivity varied between 120 and 733 m2/day. These results indicated that the potentiality of the Nubian formation is high; however, in some regions, due to the sediment heterogeneity, the aquifers have intermediate to high potential. According to the obtained results, it can be concluded that the Nubian Aquifer in Khartoum state is ideal for groundwater development. This research discovered that geophysical approaches can be used to characterize moderately heterogeneous groundwater systems by comparing the Nubian aquifer with similar aquifer systems that have similar hydrogeological settings. This study emphasized the application of universal principles in extrapolating hydraulic parameters in hydrogeophysical surveys. This approach aims to reduce the costs and efforts associated with traditional hydrogeological approaches.

“…Leptodermous expansion of the nuclear energy has proved enormously useful in calculating fission barriers, ground-state masses and deformations, and other nuclear properties [8]. Within a context related to the liquid drop model (LDM) and the leptodermous expansion of a finite nucleus, the surface and curvature energy coefficients can be extracted from semiinfinite nuclear matter [13][14][15]. This schematic geometry avoids undesired shell, Coulomb, and finite-size effects, which makes it very appropriate to study surface properties.…”

We start from the energy density of the Skyrme interaction and perform a leptodermous expansion for an asymmetric semiinfinite nuclear system. We get a liquid drop model formula for the energy of such a system. We use the obtained analytic formulae for volume, surface, and curvature energies to study the properties of asymmetric nuclear systems. We also study the effect of the asymmetry parameter on the volume, surface, and curvature properties.

Exploration of groundwater resources requires recognition of regions and their potential sources. Because of high importance in the karstic regions and their significant role in providing needed water, efforts to explore new sources of Karst is inevitable. Checking discontinuities is always an important issue in karst studies. Because of high discontinuities in rock masses, permeable areas will be created, they cause appropriate groundwater paths to flow methodology: Recognition of these regions is possible through geophysical methods based on physical characteristics of these areas such as density or resistivity. Using geophysical methods in water and geotechnical methods have less history to oil field investigations and mining exploration but have been accelerated in recent years. Results: In this research, we have tried to investigate the usage of various geophysical methods, such as how to detect and identify underground water using these methods.Conclusion: We can note of geophysical applied methods for groundwater potentiometric such as geoelectric methods, ground penetrating radar, electromagnetic, gravimetry, magnetic and seismic surveys.
