Evaluation of Olu-Obasanjo Groundwater Parameters: Application of Finite Element Concepts
Abstract
Simulation, prediction and monitoring of groundwater parameters using Galerkin's Finite Element Method were used to investigate the mass transport of groundwater parameters concentration within Olu-obasanjo Road Area in Port Harcourt upon a given distance. The mathematical model developed on the process revealed the polynomial expression of the components considered during the investigation in terms of equation of the best fit as well as the square root of the curve. The mathematical presentation of the polynomial expression is given asPc = 0.000x2 - 0.092x + 3.236 with coefficient of determinationR² = 0.963 for nitrate, Pc = 0.000x2 - 0.051x + 1.798, R² = 0.963 for chloride andPc = 1E-05x2 - 0.002x + 0.075 with the coefficient of determination R² = 0.959.All these indicate a strong relationship as established by Polynomial Regression Model. The concentration of each component can be monitored and predicted with variation in distance as well with variation in the discharge coefficient
