The increasing demand for environmentally sustainable and cost-effective landfill liner materials has created interest in the utilization of agricultural waste products as engineering materials. This study investigated the suitability of compacted bentonite admixed with Oil Palm Empty Fruit Bunch Ash (OPEFBA) as a comp…
Urban drainage systems in growing cities tend to experience capacity deficiencies and intensified runoff in the face of a changing climate. The resilience of urban drainage corridors in Asaba, Delta State, Nigeria, was investigated through scenario-based hydrologic and hydraulic modelling of five drainage corridors: Ok…
Small tropical streams used for community water supply experience simultaneous dilution, sediment mobilisation and oxygen-balance responses during seasonal transitions. This study quantified dry- and wet-season hydrodynamic and physicochemical variation along four reaches of Ikwu Stream in southeastern Nigeria and eval…
Hexavalent chromium [Cr(VI)] in industrial wastewater requires treatment methods that are efficient, affordable and adaptable to resource-constrained settings. This study compared nitric-acid-modified and non-modified rice husk in a 29-run response surface design comprising initial chromium concentration (20-100 mg/L),…
