Infiltration Models Validation in a Sandy Loam Soil in Zing, Taraba State | Chapter 13 | New Perspectives in International Plant and Soil Research Vol. 1
Predicting the infiltration
characteristics for soils is crucial for proper management and sustainable use
of soil and water resources for prevention of soil erosion. The study was
carried out to evaluate the infiltration models by measuring the field
infiltration rate on sandy loam soils in Zing. Kostiakov, Modified – Kostiakov
and Horton infiltration models were evaluated by comparing the measured and
predicted infiltration rate of the soils. Fifteen infiltration runs were made
by ponding water into double ring infiltrometer which was used to carry out the
measurements. Parameters were developed from measured infiltration data and
laboratory analyses of soil samples. Horton and Kostiakov models with an RMSE
(0.0372 and 0.0365) and the R2 value of 0.999 and 0.998 respectively, closely
predicted the measured infiltration rate, and can as well stimulate
infiltration under the field conditions.
