WATER RETENTION CURVES IN DRAINAGE PHASE OF NON-WOVEN GEOTEXTILES ESTIMAED BY SATURATED HYDRAULIC CONDUCTIVITY

Determination of unsaturated hydraulic conductivity by internal drainage assuming a uniform soil water profile

Prediction of the saturated hydraulic conductivity from Brooks and Coreys water retention parameters

[1] Prediction of flow through variably saturated porous media requires accurate knowledge of the soil hydraulic properties, namely the water retention function (WRF) and the hydraulic conductivity function (HCF). Unfortunately, direct measurement of the HCF is time consuming and expensive. In this study, we derive a simple closed-form equation that predicts the saturated hydraulic conductivity...

Measurement Scale Effect on Prediction of Soil Water Retention Curve and Saturated Hydraulic Conductivity

Soil water retention curve (SWRC) and saturated hydraulic conductivity (SHC) are key hydraulic properties for unsaturated zone hydrology and groundwater. In particular, SWRC provides useful information on entry pore-size distribution, and SHC is required for flow and transport modeling in the hydrologic cycle. Not only the SWRC and SHC measurements are time-consuming, but also scale dependent. ...

Hydraulic conductivity measurment for subsurface drainage system

Characterization of field saturated hydraulic conductivity

Papers published in Hydrology and Earth System Sciences Discussions are under open-access review for the journal Hydrology and Earth System Sciences Abstract In the context of studies aiming at the estimation of effective parameters for unsaturated zone modelling, this work tackles the problem of experimental data quality, considering the large collection of data gathered at an experimental sit...
