Influence of potable water in the characterization of habitat in African Sub-Saharan countries: Application to Cameroon
By reason of its necessity, habitat is a fundamental index in the description of the standard of living in a society. This habitat has at the center of its design and function water for consumption and sanitation. The procurement of these two essential elements for life is still a problem in Africa, particularly in Sub- Saharan Africa. Every scheme relevant to the raising of the standard of living of the...

Topology optimization method for materials zoning of a concrete face rockfill dam
For finding a reasonable layout of the fill materials in the dam body of a concrete face rockfill dam (CFRD), a new algorithm is proposed based on continuum topology optimization. In the present approach, the materials in dam are classified into several materials with different moduli and each material has a material number (an integer) according to the value of modulus. Material with higher modulus has a...

Simulation of interaction of side weir overflows with bed-load transport and bed morphology in a channel (SSIIM2.0)
To describe the complexity of flows accurately around side spillways, a 3D numerical flow model has been tested. In this study 3D numerical model SSIIM2.0 is used to simulate unsteady flows in side spillways in a schematic test channel. Side channel spillways are one of the types of outlet works at dams with wide applications in irrigation, drainage systems, in water and wastewater facilities....

Mud rotary drilling in Southern Nigeria: Potential adverse effects of its by-products on the environment
Boreholes are the major sources of potable water for households, communities, institutions and industries in Nigeria and the number of these boreholes continues to rise and does not show any sign of abatement. Among the current methods used for drilling boreholes, mud rotary drilling has been consistently chosen due to its low cost and efficient operation. However, no attempt has been made to assess the...

Water quality assessment of a wastewater treatment plant in a Ghanaian Beverage Industry
The research is aimed at assessing the performance of the wastewater (excluding sewage) treatment plant in a Ghanaian beverage industry. Sixteen (16) water quality parameters were analyzed by collecting influent and effluent wastewater samples of the treatment plant for a year and their average values were compared with EPA (Ghana) guidelines for beverage industries discharging into water bodies. Most of the...

Stratigraphic mapping of subsurface structures and groundwater potentials from electrical resistivity soundings in Onicha Olona, Atuma Iga and Akwukwu-Igbo, Delta State Nigeria
Onicha Olona, Atuma Iga and Akwukwu-Igbo have experienced severe hardship in getting reliable boreholes over many years due to their high topography. They are transition towns as it is from here that marked variations in subsurface structures and topography commence. Although the entry point at onicha Olona which is tied to Issele Uku is a flat land by contouring, the western end of the town has evidence of...
