Comparison of Saturated Hydraulic Conductivity Estimated by Three Different Methods
This study compares saturated hydraulic conductivities (Ks) of three sandy soils such as coarse, medium and fine sand. The Ks was obtained using three different methods: empirical methods based on the grain size analysis, the relative effective porosity model (REPM), and breakthrough curve analyses based on tracer tests. Column drainage tests were performed to characterize the water retention p...
متن کاملComparison of three measurement methods of saturated hydraulic condutivity
After pointing out the importance of the saturated hydraulic conductivity (ks) measurements and the difficulties and uncertainties that are present, and after recalling salient aspects of three well-known measurement methods of this parameter (i.e. constant-head tension infiltrometer (TI) method, constant-head pressure infiltrom5 eter (PI) method and soil core (SC) estimates method), the result...
متن کاملEffect of pH on Saturated Hydraulic Conductivity and Soil Dispersion
The adverse effects of exchangeable sodium on soil hydraulic conductivity (K) are well known, but at present only sodicity and total electrolyte concentration are used in evaluating irrigation water suitability. In arid areas, high sodicity is often associated with high dissolved carbonate and thus high pH, but in humid areas high sodicity may be associated with low pH. To evaluate the effect o...
متن کاملMeasurement methods of saturated hydraulic condutivity
Papers published in Hydrology and Earth System Sciences Discussions are under open-access review for the journal Hydrology and Earth System Sciences Abstract After pointing out the importance of the saturated hydraulic conductivity (k s) measurements and the difficulties and uncertainties that are present, and after recalling salient aspects of three well-known measurement methods of this param...
متن کاملMeasurement 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. ...
