Abstract

Hydraulic properties of soils and their applications in water flow models have a marked role in solution of some managemental problems. There are many models to predict soil moisture retention curve. Such a curve was determined for three sites (silt loam, and loam) were determined. Then the performances of four common oversea PTFs (Rawls and Brakensiek, Vereecken et al., Wosten, and Wosten et al.) and four local ones (Ghorbani Dashtaki and Homaee, and Farrokhian Firuzi and Homaee) were traced. Sand table and pressure apparatus were used for soil water content values corresponding to low (0-1 meters) and high suctions (> 1 meter), respectively. All the measurements were done on undisturbed samples. A statistical evaluation test was conducted on measured and predicted water contents. Although the results were not so good, yet Vereecken et al., and Wosten PTFs, among oversea models, were relatively acceptable. The performances of both models of Ghorbani Dashtaki and Homaee, especially at higher suctions, were good. The other local PTFs of Farrokhian Firuzi and Homaee resembled unsatisfactory performance. Therefore, there is a need that suitable PTFs are to be determined for gupsum and CARBONATED SOILS corresponding especial features of Iran.
