Assessment of Pedotransfer Functions for Saturated Hydraulic Conductivity of Anatolian Soils

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...

Estimating Hydraulic Conductivity Using Pedotransfer Functions

development of some pedotransfer functions to predict the saturated hydraulic conductivity of gravel soils using partial least square regression method

abstract saturated hydraulic conductivity (ks) is one of the most important physical properties of soils which is expensive and time-consuming to directly measure. hence, indirect methods, such as pedotransfer functions (ptfs), were developed to predict the ks. previous studies showed that most of the ptfs common in the literature can not suitably predict the ks. hence, this study was conducted...

Estimating the Saturated Hydraulic Conductivity of Soil Using Gene Expression Programming Method and Comparing It with the Pedotransfer Functions

Saturated hydraulic conductivity of soil is an important physical property of soil that affects water movement in soil, Since the measurement of saturated hydraulic conductivity by direct methods in the field or in the laboratory is hard, time-consuming and costly, the indirect methods are being used.The aim of this study is to estimate the saturated hydraulic conductivity from other soil prope...

Evaluation of two methods for measuring saturated hydraulic conductivity of soils under two vegetation covers

The main goal of this work is to determine and to evaluate the saturated hydraulic conductivity for a silt loam soil in field and laboratory conditions. The experimental area was located in the Vallcebre research catchments, in headwaters of the Llobregat River (NE Spain). Hydraulic conductivity was measured in the field using the Guelph permeameter and field saturated hydraulic conductivity (K...
