rosetta: a computer program for estimating soil hydraulic parameters with hierarchical pedotransfer functions
TL;DR: In this paper, the authors describe a computer program, rosetta, which implements five hierarchical pedotransfer functions (PTFs) for the estimation of water retention, and the saturated and unsaturated hydraulic conductivity.
Journal ArticleDOI
Neural network analysis for hierarchical prediction of soil hydraulic properties
TL;DR: In this article, neural network models were developed to predict water retention parameters using a data set of 1209 samples containing sand, silt, and clay contents, bulk density, porosity, gravel content, and soil horizon as well as water retention data.
Journal ArticleDOI
Database-related accuracy and uncertainty of pedotransfer functions
Marcel G. Schaap,Feike J. Leij +1 more
TL;DR: Three databases are employed for calibration and validation of PTFs to predict soil hydraulic properties from soil texture, bulk density, and organic matter content.
Journal ArticleDOI
Improved Prediction of Unsaturated Hydraulic Conductivity with the Mualem-van Genuchten Model
Marcel G. Schaap,Feike J. Leij +1 more
TL;DR: In this paper, the Mualem-van Genuchten model was used to predict unsaturated hydraulic conductivity from water retention parameters and neural network analyses confirmed that K 0 and L could indeed be predicted in this way.
Journal ArticleDOI

Harry Vereecken,Mélanie Weynants,Mathieu Javaux,Mathieu Javaux,Ya. A. Pachepsky,Marcel G. Schaap,M. Th. van Genuchten +6 more
TL;DR: In this article, the authors reviewed the use of the van Genuchten-Mualem (VGM) model to parameterize soil hydraulic properties and for developing pedotransfer functions (PTFs).
