Soil’s infiltration characteristics remain important variables of consideration in irrigation systems designs as well as in soil and water management. This work was conducted to evaluate the performances of three different infiltration models (Kostiakov, Horton and Philip) in order to select a suitable model for use in determination of infiltration characteristics of soils neighbouring Bayero University, Kano-Nigeria. Experiments were conducted in three different locations within the study area and the performance of each model was analysed and compared against a direct measurement using double ring infiltrometer. The results showed no significant difference (Least significant difference = 0.29 @ 0.05 level of significance) between the direct measurement on field and the result obtained using Kostiakov and Horton’s model having mean infiltration rate of 1.05 and 1.04cm per minutes respectively, while the Philip’s model showed a significant difference in means (1.76cm/min) indicating higher sensitivity of its measurement. There was no significance difference (p=0.19 @ 0.05 level of significance) on replicating the experiment for the 3 different locations. Thus, the Kostiakov’s and Horton’s models were recommended for the infiltration characteristics measurement in Kano and elsewhere with similar environmental conditions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
