xi 
dimensionless coordinate (see 
xi0 
displacement of wetting front expressed as
dimensionless coordinate (see 
a 
vector of coefficient returned by

the dimesioneless solution, i.e. the variable H
The expession for the dimensionless coordinate (Song at al., 2007) is ξ=x (\frac{2 \, s }{η_1 \, K_s \, t^{α+1} } )^{1/2} and the solution for the dimensionless equation derived by Boussinesq Equation is: H = ∑_{n=0}^{∞} a_n (1\frac{ξ}{ξ_0} )^n for ξ<ξ_0 , otherwise is 0 .
