Synthesis of soil

We collected soil-hydraulic property data from the literature for wildfire-affected soils, ash, and unburned soils. These data were used to calculate metrics and timescales of hydrologic response related to infiltration and surface runoff generation. Sorptivity (S) and wetting front potential (Ψf) were significantly different (lower) in burned soils compared with unburned soils, whereas field

ASTM D7100

4.6 Hydraulic conductivity of a soil with water and aqueous solution can be determined using two approaches in a test program for comparisons between the hydraulic conductivity based on permeation with water and the hydraulic conductivity based on permeation with aqueous solution. In the first approach, specimens are initially saturated (if needed) and permeated with water and then the

PREDICTING SATURATED AND UNSATURATED HYDRAULIC

Hydraulic conductivity is likely the most important soil property controlling water and solute movement in soils. It is also one of the most variable and uncertain soil properties. Models for predicting soil hydraulic conductivity from other soil characteristics are, therefore, useful in both deterministic and stochastic transport studies. The new K S model compared well with measurements when

Effects of Compaction on Soil Hydraulic Properties

Unfortunately, comparative soil hydraulic properties or soil hydrologic components for various management systems are often not consistent (Culley et al., 1987b ). Given specific soil management operations, few general statements can be made to describe the effects of compaction on soil hydraulic properties and soil hydrology (Baker, 19~).

Jun 17, 2019Soil hydraulic conductivity was measured across different zones in a farmer's field, and its spatial variability was investigated by using geostatistical techniques. Since direct measurement of hydraulic conductivity is time-consuming and arduous, pedo-transfer functions (PTFs) have been developed to estimate hydraulic conductivity indirectly
