Saltwater Intrusion in Nigeria: A Review

Environmental Technology and Science Journal
Across some areas in Nigeria such as; Lagos State and the Niger Delta region, freshwater supplies have been negatively impacted by saltwater intrusion, a growing environmental hazard that has affected coastal aquifers worldwide. The causes, effects and mitigating techniques of saltwater intrusion in the coastal areas of Nigeria are examined in this ...

A novel subsurface adjustable dam for preventing active seawater intrusion in coastal aquifers

Frontiers in Marine Science
Subsurface physical barriers are widely used to prevent seawater intrusion in the world. After the construction of physical barriers, the residual saltwater is trapped upstream the barriers.

Optimized Selenium‐Doped Nanocomposites for Enhanced Polymer Gel Performance in Permeability Reduction

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Excessive water production in mature oil fields necessitates robust shut‐off treatments, yet conventional polymer gels often fail under high‐temperature and high‐salinity conditions. This study aims to enhance gel thermal stability and mechanical strength by incorporating selenium‐doped Ag/AgO–ZnO nanocomposites synthesized via a novel green ...

Does sea-level rise have an impact on saltwater intrusion?

, 2011
Climate change effects are expected to substantially raise the average sea level. It is widely assumed that this raise will have a severe adverse impact on saltwater intrusion processes in coastal aquifers.

Synergistic Physicochemical Inhibition of Reactive Shale Formations Using Hydrothermally Synthesized Hydroxyapatite Nickel Tungstate Nanocomposites in Water‐Based Drilling Fluids

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Wellbore instability driven by the volumetric expansion of reactive shale formations remains a primary operational challenge in modern drilling engineering, causing severe mechanical failures and substantial economic deficits. The objective of this study is to formulate and evaluate a novel dual‐action chemical additive capable of ...

Potassium hydroxide activation of microalgal biochar for improved adsorption efficiency

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Activated carbon was prepared from Chlorella by carbonization and potassium hydroxide activation, and its structural properties and methylene blue (MB) adsorption performance were evaluated. Raw Chlorella exhibited an adsorption capacity of 287.2 mg g−1, which decreased to 214.8 mg g−1 after carbonization.
