About this document
Van Genuchten Equation for Soil-Water Curve by Kárita Kanaiama is a document available to read on EtoBox.
The document proposes a new equation to characterize the soil-water characteristic curve over the entire suction range based on pore-size distribution. It reviews existing equations that do not accurately fit data over the full range. The proposed equation models the curve as an integrated frequency distribution function. Non-linear regression is used to determine best-fit parameters for experimental data from literature. The equation provides a good fit for sands, silts and clays from 0-10,000kPa suction.
