Composite Goodness of Fit in Reaeration Coefficient Modeling

Determination of reaeration coefficient is an important factor in surface water quality modeling as it determines the efficiency of the Streeter-Phelps model used for predicting dissolved oxygen deficit of any stream. This study compared the efficiency of Atuwara model with ten other reaeration coefficients models by making use of three data sets obtained from river

Sustainable Groundwater Exploitation in Nigeria

In this study, a critical review of the groundwater resources history and management in Nigeria was done. The aim was to identify reasons why groundwater is increasingly being exploited in recent times, and to explore ways through which the exploitation could be done sustainably. This was achieved through literature review. It was observed that an

An Approach to Reaeration Coefficient Modeling In Local Surface Water Quality Monitoring

Abstract Reaeration coefficient (k2) for River Atuwara, Ogun State, Nigeria was calculated from dissolved oxygen and biochemical oxygen demand data collected over period of 3 months covering the two prevailing climatic seasons in the country. Both the Akaike and Bayesian information criteria were used in the selection and analysis of ten models to identify the

An Evaluation of Slaughterhouse Wastes in South-West Nigeria

This study was carried out at ten randomly selected slaughterhouses situated in Lagos and Ogun States,Nigeria. The aim was to evaluate the current waste generation and waste handling practices while exploring the possibility of reducing to the barest minimum the percentage of live weight cow that is considered as waste. This was achieved through questionnaire

Effect of industrial effluents on water quality of River Atuwara in Ota, Nigeria. In Adeyemo, R. (ed), Urban Agriculture, Cities and Climate Change. Cuvallier Verlag, Gottingen, Germany, ISBN: 978-3-86955-813-4, pp.272-280

The impacts of industrial wastewaters discharged into River Atuwara were estimated from the physical and chemical characteristics of the samples using standard methods. The quality of the effluent before and after dilition in the receiving water and impact on the use of the water for irrigation was studied using QUAL2K software for hydrodynamic analysis of

Passing on the Baton to Future Water Resources Scientists & Engineers in Developing Nations

Education is important for the proper management of water resources in any nation, especially in developing nations that are faced with other equally important competing issues. In West Africa, as a developing region, in addition to other economic problems, there exists severe groundwater related issues. Working with students in those nations is one way of

Study of Auto Purification Capacity of River Atuwara in Nigeria

The aim of this paper was to study and predict the self-purification capacity of River Atuwara. This was done primarily by measuring the Dissolved Oxygen (DO) downstream of a pre-selected pollution discharge point on River Atuwara and then predicting the same using the modified Streeter-Phelps equations. Other data gathered from each of the 17 sampling

Reaeration Coefficient Modeling: A Case Study of River Atuwara in Nigeria.

A study of the self purification capacity of River Atuwara was done with the aim of developing a reaeration coefficient model, k2, for the river. The k2 model was evaluated and validated by comparing its performance with the Streeter-Phelps and Agunwamba models. Atuwara model was developed using non-linear regression while its performance was checked by

Comparative Germination Studies of Cowpea (Vigna unguiculata Linn. Walp) and Soy bean (Glycine max Linn. Merr) on Whole and Water Saturated Fractions of Hydrocarbon (Hexane)

The effects of whole and water saturated fractions (WWSF) of hydrocarbon hexane on the germination of two leguminous crops: Vigna unguiculata (Linn) Walp and Glycine max (Linn) Merr were investigated at the green house of Botany and ecological department university of Uyo Akwa- Ibom State, using Petri dishes at room temperature (±280C), between July and
