| Abstract | The study was conducted at Surakarta- Indonesia during rainy
season in 1987. The double ring infiltrometer method was used to
measure 15 field infiltration for 5 plots.
To characterize the infiltration, the Green-Ampt, Kostiakov,
Horton and Philip model were used. Philip model provided the
best agreement with experimental data, with some underestimation
at early stages and good estimation for the following stages with
mean = 0.994. Horton model gave more underestimation at early
stages and also provided good of fit for the following stages
(mean Ri = 0.964 ) . Kostiakov model overestimated at small time
and underestimated at large time (mean R2 = 0.975 ) . Green- Ampt
model gave negative A- contant , and seems to be least applicable.
In Kostiakov model (I =atn ), n-parameter increases with
initial wetness (0i), ~ = 0 .790) and dry bulk density ( b)
(r *=0.765 ), whereas a - parameter decreases with fb (r *=0 . 799 ) . The
parameters in Horton model ( I =ic t +1/ k (io- ic ) [1- exp(- kt ) ] do
not depend on initial volumetric wetness (0i), dry bulk density
( fb ) , total porosity (0s) and saturated conductivity (Ks), as
well as there is no any relation among parameter. While in
Philip model (I =Sp tt + Ap t ) , Sp-parameer has poor relation
with initial wetness and saturated conductivity, but it would be
increased with available storage in the topsoil ~ = 0.649 ) , total porosity ~ =0.597 ) and clay content in the topsoil ~
=0.871 ) . Sp-parameter dcreases with dry bulk density ~
=0.674 ) , and sand content in the topsoil (r ~ =0.925 ) . Ap- parameter does not have relation with any soil properties. |
