ABSTRACT

A study was carried out to determine the efficiency of different models for estimating hydraulic conductivity in soils of coastal plain sands of Oboro clan – Ikwuano Local Government area in Abia State. Representative undisturbed soil samples were collected from 8 communities and their properties determined using standard laboratory methods and experimental models. Five different models were used to estimate the saturated hydraulic conductivity (Ks) of the soils of the study area, these models were Hazen, Relative Effective Porosity Model (REPM), Slitcher, Terzaghi and Kozeny-Carman Models.  Soil properties determined include depth, aggregate sizes, bulk density and porosity. The predicted and observed soil properties were compared using multiple linear regression test. Further evaluation of the accuracy of prediction on the models used in comparison with the laboratory Ks values were carried out with absolute mean percentage error. Generally, the results showed that the soils are of Sandy Basic soil type. There was a significant positive correlation (P<0.001) between bulk density and porosity. The hydraulic conductivity maximum and minimum values of Kozeny-Carman, Hazen, Slitcher, Terzaghi and Relative Effective Porosity Model (REPM) were 67.68m/day and 0.86m/day, 18.72m/day and 0.86m/day, 9.50m/day and 0.29m/day, 68.25m/day and 1.15m/day, 191.52m/day and 2.59m/day respectively. The result indicated that the hydraulic conductivities calculated by Slitcher models is in all cases lower than that from the other models as well as from pressure plate apparatus test result. Saturated hydraulic conductivity estimated using REPM gave the highest Ks value of 191.52m/day. This study therefore concluded that the best overall estimation of Ks is reached based on relative effective porosity model followed by Terzaghi and then Kozeny-Carman models. The research recommended that Relative Effective Porosity Model (REPM) as the best and useful alternative for estimating Ks of soils within the South-Eastern Nigeria.
