| Abstract | Infiltration as a term describes the flow of water through the soil surface. It also describes the process by which water soaks and is absorbed by the soil. Slopes of varying steepness and aspect will get different amount of rainfall-runoff which may influence the amount of infiltration. The study is aimed at examining the influence of slope on the variability of infiltration capacity in Obudu Local Government Area of Cross River State, Nigeria. The slope was dichotomized into three segments based on the geomorphological zonation. Four transects were marked out in each of the slope segment. Two soil samples were randomly collected at the upper, middle and bottom slopes and were taken to the laboratory for the analysis of moisture content. The steel cylinder were firmly driven into the soil to a depth of 5cm with the aid of a hand hammer. The wooden plates were then used to ascertain if the steel cylinders are balanced enough. The wooden plates were then placed on the steel cylinder and invert the already filled bottle on it through a hole on wooden plate. Reading starts immediately the bottles have been inverted over the steel cylinder. The data from each test were expressed in the form of the Talsma-Parlange equation which is also similar to the Philip‟s two equation in terms of sorptivity, S, and the saturated hydraulic conductivity, ks. The results revealed that there was no obvious variation in the values of infiltration on the upper, middle and bottom slope segments. The ANOVA results further established the difference between the values of infiltration, diffusion and transmission contents and the mean of infiltration capacity on the upper, middle and lower slope segments along the toposequence. The result revealed an insignificant variation in the values on the various segment of the slope. The study has established how much of an influence slope has on water infiltration as a geomorphic process. |
