abstract = "The practical application of determination of the soil
water retention curves (SWRC) is in seepage modelling
in unsaturated soil. The models based on the physics
behind the seepage mechanism has been developed for
predicting the SWRC. However, those models rarely
consider the combined effects of initial volumetric
water content and soil density. One of the best routes
to study these effects is to formulate the SWRC
models/functional relations with volumetric water
content as an output and the soil density, initial
volumetric water content and soil suction as input
parameters. In light of this, the present work
introduces the advanced soft computing methods such as
genetic programming (GP), artificial neural network and
support vector regression (SVR) to formulate the
volumetric water content models based on the suction,
density and initial volumetric water content. The
performance of the three models is compared based on
the standard measures and goodness-of-fit tests. The
findings from the statistical validation reveals that
the GP model performs the best in generalizing the
volumetric water content values based on the suction,
density and initial water content. Further, the 2-D and
3-D plots, evaluating the main and the interaction
effects of the three inputs on the volumetric water
content are generated based on the parametric procedure
of the best model. The study reveals that the
volumetric water content values behave non-linearly
with respect to soil suction because it first decreases
till a certain point of soil suction and then increases
suddenly.",
