This empirical research study evaluates the slope recession in Ikpoba River Basin. The study adopted the experimental research design and direct field measurement primary data collection of rainfall events together with erosion variables at point location. The use of erosion rods to collect data involved monitoring erosion variables at the valley slope, to determine advance and retreat of eroded soil. However, the rainfall as well as the soil and slope characteristics event was monitored. This was carried out for a period of five (5) months (April to September excluding August) with the installation of thirty (30) erosion rods along a transect line down the slope. The rainfall amount was measured using autograph rain gauge at Benin Owena Meteorological station. Runoff amount was measured using an Ott-type-current meter with which the velocity was taken. The data collected were subjected to PPMCC Correlation and Regression Statistical Analyses. The hypotheses (H0) states that there is no significant relationship between rainfall amount and slope recession in Ikpoba River valley slope was tested. The result of the hypothesis showed that most rainfall events studied are unsatisfactory in predictors of slope recession but suggestion is made on that standardized diagnostic rainfall amount in slope recession, are of value only within clearly defined environment. The result of the findings also revealed the level of slope recession might be predicted with some degree of accuracy, based on rainfall. The study concluded that rainfall amount are significantly related to slope recession. The study recommended that since slope is very important, the understanding of the natural landscape to create awareness in soil erosion control, sedimentation and managing agricultural land areas along such slopes are required.
