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. ...
متن کاملsimultaneous scaling of soil water retention and hydraulic conductivity functions
abstract scaling methods, which are based on similar media theory, are used to simplify the statistic description of soil spatial variations. to simulate the water flow in heterogeneous soils, simultaneous scaling of soil hydraulic functions, including soil water retention and unsaturated hydraulic conductivity functions, is highly desirable. in the similar media theory, the simultaneous scalin...
متن کاملDiscussion “Determination of the Hydraulic Conductivity Function of a Highly Compressible Material Based on Tests with Saturated Samples”
The discussers have read this paper with considerable interest and, like the authors and many others, they have also observed that compressibility can significantly influence the unsaturated properties of soft materials. Obtaining valuable experimental results on these types of materials is quite a challenge, and the authors should be commended for their effort to measure the WRC of deinking re...
متن کاملWater Retention and Characteristic Curve
A soil-water characteristic (SWC) curve describes the amount of water retained in a soil (expressed as mass or volume water content, m or v) under equilibrium at a given matric potential. An SWC is an important hydraulic property, related to size and connectedness of pore spaces, hence strongly affected by soil texture and structure, and by other constituents, including organic matter. Modeling...
متن کاملEstimation of Water Retention Curve for Unsaturated Fine Soils
In order to obtain the soil water retention curve of an unsaturated soil which is defined as the relationship between water content and suction, extensive laboratory tests are essential. These laboratory tests are usually costly and time consuming. Moreover, for most practical problems, it has been found that approximate unsaturated soil properties are adequate for analysis. Thus, empirical pro...
