Abstract The Nubian sandstone aquifer (NSA) is defined by using 19 vertical electrical sounding (VES) stations, 201 gravity which define the structures that control configuration of NSA, and 183 land magnetic lower surface NSA determining depth basement surface. In order to assess top we collected analyzed deep VESes. upper spans from 707 1154 m, according interpretation results for various geo...

Water is a natural resource; its availability depends on climatic and geological conditions, it invariably controlled by human activities. Agbado-Ijaye lies within coastal area, where local communities have been facing incessant water shortages, especially during the dry season. This study investigated groundwater-bearing unit(s) using hydrogeophysical techniques in environment. The electrical ...

Geoelectrical resistivity sounding surveys was carried out at two locations (A and B) in the new CanaanCity residential estate of Canaan land Ota, Ogun state order to locate possible targets for groundwater explorations. A total twelve (12) vertical electrical soundings were conducted using Schlumberger array configuration. The interpretations VES curves revealed five six geoelectrical layers l...


 In Nnewi, Anambra State Nigeria, twenty vertical electrical sounding (VES) were performed to delineate vulnerability and transmissivity of identified aquifer within the study area. Hydraulic parameters (transverse resistance, longitudinal conductivity, hydraulic conductivity transmissivity) delineated from geoelectrical (depth, thickness, apparent resistance). The geo- aquifer: resistanc...

The interpretation of simultaneous ionospheric Doppler sounding and ground magnetometer observations of low-latitude Pi2 waves is revised. We compare the theoretical estimates of the ionospheric Doppler velocity for the same amplitude of the ground magnetic disturbances produced by a large-scale compressional mode and an Alfvén mode. The plasma vertical displacement caused by the wave electric ...

Site characterization is a prerequisite for the successful and economic design of engineering structures earthworks by providing geological information any proposed project. Until now, no detail study has been carried out on site classification using shear wave velocity (Vs) up to top 30 m depth in Hawassa town. For this study, multichannel analysis surface waves (MASW) was used determine varia...

In this study, building failures were investigated in Damaturu metropolis, using Electrical resistivity method which involves, both Vertical Sounding (VES) and Resistivity Tomography (ERT). The study reveal that the area is composed of five geologic layers, are topsoil, clay, sand, sandy-clay, sand. topsoil thickness ranged from 0.7 to 1.9 m has values 127.6 171.5 Ωm. second layer a clay format...
