Assessment and Prediction of Groundwater for Irrigational SuitabilityBy C.F. Ikebude, C. Ukpaka
Abstract: Assessment of ground water suitability for irrigation purposes in Egita community has been investigated. The study gave sodium absorption ratio (SAR) values for different weeks of study. The values obtained ranges between 0.33 to 0.37 for both empirical model and finite element method respectively. The research demonstrates the suitability of using finite element method in predicting and monitoring sodium absorption ratio in groundwater water modelling and investigations. The correlation between …

Predictive Model on Constant Pressure Drop Variable: Area Fluid Flow System in a PipeBy C. Ukpaka, Tamuno-omie Alalibo
Abstract: The effect of density, pressure drop, and orifice area was examined in this research. The basic equation developed to represent steady-state fluid flow is the Bernoulli equation which assumes that the total mechanical energy is conserved for steady incompressible, in viscid, isotherm flow with no heat transfer or work done. These restrictive conditions can actually be representative of many physical systems. The Bernoulli’s principle was applied in explaining the design …

Mathematical Models and Forecast of Effect of Flow Rate on Turbidity and Total Suspended Solids Within Water Bearing AquiferBy C. Ukpaka
Abstract: The aim of study is to develop mathematical models to predict turbidity and total suspended solids upon the influences of recharge and flow rate as a functional parameter in distribution interaction of water parameters within the water bearing aquifer taking a main well A as dispersing point to other wells. Predictive models have been generated to account for the effect of flow rate on turbidity and total suspended solids within …

Empirical Model Relativity of Flexural and Compressive Strength of Concrete Produced with Foundry Waste Sand as Partial ReplacementBy C. Ukpaka, G. C. Jula
Abstract: The evaluation presented in this research is to establish the correlation between compressive strength of concrete and flexural strength of concrete of grade 20 at mix ratio of 1:2:4 produced using foundry waste sand as a partial replacement for river sand at different replacement level of 0%, 5%, 10%, 15%, 20% and 25%. The aimed compressive strength was achieved at 15% replacement and the corresponding flexural strength of 3.14 N/mm2was …

Simulation of Sediment Deposit and Maintenance Requirements for Sani- Abacha Road Culvert, Rivers State, NigeriaBy C. Ukpaka, C.G. Jula
Abstract: Empirical model of sediment yield equation was applied to develop the sediment deposit monitoring equation of the Sani-Abacha road culvert. The culverts were selected based on field observation of continuous overflow, road overtopping and channel contraction in the course of heavy storm due to sediment built up within and inside the culvert barrel. The result of the assessment shows that the way sediment load varies with discharge is consistent and …

Rating of Water Quality of Rivers Water in Asari Toru L.G.A, Rivers State, NigeriaBy C. Ukpaka, J.C. Ozota
Abstract: The aim of the assessment was to compute the water quality index (WQI) of Sama and Tema River at 20metres interval along horizontal direction of the river to determine the suitability of the water for purposes of public drinking, recreation and other usage. In this paper the functional parameters in evaluating quality of a water body were used in evaluating the water quality index (WQI) of the two river and …
