The optimization effects of the particle swarm optimization (PSO) on the parameters of Van Genuchten (VG) equation for the soil water characteristic curve were investigated. The results indicated that the VG parameters determined by the PSO were very close to those of experiments with a very high accuracy. The PSO was proven to be used as an optimization method for estimating VG parameters for the soil water characteristic curve. The PSO had the higher parameter precision than the damped least squares method and the nonlinear simplex method. The particle swarm optimization was improved and its convergence accuracy was higher than that of constriction factor particle swarm optimization (CFPSO) and PSO of Filedsend.
