There is no golden rule concerning the optimal equations to estimate reference potential evapotranspiration (PETref) under various climates because even in the same climatic type, different studies have produced mixed results in relation to the performance of the empirical PETref equations...

The production of bio-pellets is an alternative to add value to the residual biomass of the oil palm-extraction process. In this work, an experimental study of the pelletising process of oil palm residual biomass blends is presented. An experimental full factorial design that uses as factors the...

Deep groundwater data reflects hydrological processes, climate change and variability, as well as any anthropogenic influence. Decomposition of deep groundwater signal examines the history of the groundwater region. Detrending is a vital step in decomposition of groundwater time series because it is...

The purpose of the present work is to test the possibility of using the spent tea dust and raw coir pith for the removal of methylene blue (MB) from aqueous solution. The effects of the contact time, adsorbent dosage and solution pH were studied in batch experiments at 27 °C. Results showed that a...

Removal of Al 3+ and Mn 2+ from solution by Trichoderma asperellum BHU216 immobilized on Irvingia gabonensis matrix in a batch system was investigated. Effect of biosorption conditions contact time, pH, bead size and spore load were studied. Equilibrium isotherms and re-usability of biosorbent were...

Poor appreciation of Wetlands has been linked to their massive destruction in Nigeria. This results in a considerable loss of benefits on income generation, food security and environment sustainability. This study assesses people’s perception of benefits from selected Wetlands in South West, Nigeria...

The Alfeios River is the greatest in length and flow-rate river in Peloponnisos and constitutes an important water resource and ecosystem of Western Greece. A number of infrastructure works and human activities have been constructed and are operating in Alfeios River Basin, while in the past...

Physicochemical parameters and nutrient loads of major rivers and streams in Abakaliki, Ebonyi State were studied for a period of seven (7) months from May to November, 2011. Regular and constant monitoring of water bodies is vital to ensure that water quality characteristics are maintained. The...

The Great Lakes form an important freshwater drinking source for many urban areas surrounding the Lakes but also provide a sink for pollutants and runoff. Consequently introducing new drinking water intakes into any of these water bodies requires investigation into local pollutant sources and their...

A key component in the implementation of Water Framework Directive is the development of a river basin management plan for each river basin district. Water quality models are important tools to test the effectiveness of alternative management plans on the water quality of the respective water bodies...
