Modeling the transport of suspended particulate matter by Kwa Ibo River, Umudike, South-eastern Nigeria: Implications for pollutant dispersion

Modeling the transport of suspended particulate matter by the Kwa Ibo River, Umudike, south-eastern Nigeria is the focus of this paper. The model solves the 3D hydrodynamic equations and the suspended matter equations including advection/diffusion of particles, settling and deposition. It is aimed at assessing the extent of the interaction between the Kwa Ibo River and the viable groundwater wells located within the...

Rondon project: Addressing water issues in socio-economically disadvantaged communities in Brazil

The northeastern region of Brazil has embattled a severe drought for centuries making it almost impossible to supply the local communities with adequate drinking water.  As part of their outreach program the university of Zumbi dos Palmares was contracted by the Ministry of Defense to provide the necessary technical expertise to build a water cistern in the town of Maranhao. One of the project requirements was that...

Integration of very low-frequency electromagnetic (VLF-EM) and electrical resistivity methods in mapping subsurface geologic structures favourable to road failures

An integrated geophysical survey involving very low-frequency electromagnetic (VLF–EM) and the dipole-dipole electrical resistivity methods was carried out along the Auchi-Ibillo road in Igarra, Nigeria with a view to examining factors responsible for road failures in the area. Analysis of very low frequency electromagnetic current density sections and dipole-dipole pseudo-sections were made along three traverses....
