Spatial patterns of wetting characteristics in grassland sandy soil

Journal of Hydrology and Hydromechanics, 2016
In grasslands where organic and inorganic resources are alternating at scales of individual plants, the transient character is given to certain wetting properties of soil, which then become highly variable both in space and in time.

Estimation of Soil Hydraulic Properties Curve through Beerkan Infiltration Experiment Algorithms

علوم آب و خاک, 2019
Nowadays, the Beerkan computational algorithms (BESTslope and BESTsteday) are known as the suitable indirect methods for estimating soil saturated hydraulic conductivity (Ks) and sorptivity (S), as well as the scale parameter (hg) in van Genuchten soil ...

Does no-till cover crop influence in situ measured soil water potential and saturated hydraulic conductivity?

Soil and Water Research
Soil water energy determines soil water balance, plant water uptake, and soil thermal properties, but the effects of cover crops (CCs) on in situ measured soil water energy and temperature are not well understood.

Experimental study of lightweight concrete prepared from super absorbent polymers (SAPs) and glass fibers (GF)

Journal of Asian Architecture and Building Engineering
This study investigates the effect of super absorbent polymers (SAPs) and glass fiber (GF) additions on the properties of lightweight concrete. The SAPs act as a pore-forming agent, with the addition of various GF contents (0.1–1.0% by weight of dry ...

New automatic minidisk infiltrometer: design and testing

Journal of Hydrology and Hydromechanics, 2015
Soil hydraulic conductivity is a key parameter to predict water flow through the soil profile. We have developed an automatic minidisk infiltrometer (AMI) to enable easy measurement of unsaturated hydraulic conductivity using the tension infiltrometer ...
