Abstract
Overestimation of vertical infiltration rate as a result of diverges laterally flow is a major
problem in the use of infiltrometers. Although, the double-ring infiltrometer minimizes the
error associated with lateral divergence, no specific dimension has been given for its usage.
This report gives an investigation of the effect of dimension of double rings infiltrometer on
the infiltration rate at the University of Agriculture Abeokuta. This study was conducted
during the dry season and wet season on a vegetated land in the year 2011. Three pairs of
double rings infiltrometer were used comprising of 30:60, 15:30 and 7.5:15 cm diameter
rings. The 15:30 dimension offered the best accuracy with significant (p = 0.01) coefficient of
determination of infiltration, followed by the 7.5:15 cm rings and lastly the 30:60 cm ring.
The relative reliability of each dimension in terms of accuracy of measured infiltration data
utilized was assessed by the mean of result of infiltration rate from the three pairs of double
rings infiltrometer.
