Comparison of Pedotransfer Functions for Determination of Saturated Hydraulic Conductivity for Highly Eroded Loess Soil

نویسندگان

چکیده

Saturated hydraulic conductivity is one of the most essential soil parameters, influencing surface runoff and water erosion formation. Both field laboratory methods measurement this property are time or cost-consuming. On other hand, empirical very easy, quick costless. The aim work was to compare 15 pedotransfer models determination their usefulness for assessment saturated highly eroded loess soil. mean values obtained by use analyzed functions fluctuated between 2.00·10−3 4.05·100 m·day−1. results calculations were compared within them with method. function that best comparable method ones proposed Kazeny-Carman, based on void ratio specific area, Zauuerbrej, total porosity effective diameter d20. In turn, completely differed Seelheim, d50 Furnival Wilson, bulk density, organic matter, clay silt content. important analysis among others

Scale-Dependent Pedotransfer Functions Reliability for Estimating Saturated Hydraulic Conductivity

Saturated hydraulic conductivity Ksat is a fundamental characteristic in modeling flow and contaminant transport in soils and sediments. Therefore, many models have been developed to estimate Ksat from easily measureable parameters, such as textural properties, bulk density, etc. However, Ksat is not only affected by textural and structural characteristics, but also by sample dimensions e.g., i...

Changes of the Saturated Hydraulic Conductivity of Soil Influenced and Exchangeable Sodium Percentage (%ESP)

Sodic soil is one of the most common problems of limiting agricultural production that related on irrigation. Saturated hydraulic conductivity is one of hydrodynamic characteristics in evaluating transmission flow through underground levels. To investigate the role of increment of exchangeable sodium in hydraulic conductivity changes (as characterized by the mobility of water in soil) an experi...
