Efficient Laboratory Measurements of the Soil Water Retention Curve

Geotechnical Testing Journal, 2013
Abstract The knowledge of the soil water retention curve (SWRC) is of particular importance for unsaturated soils. However common techniques to determine SWRC may be much more time-consuming than other soil property testing techniques and may lack flexibility in controlling the stress state of the soil in the field, which is of most ...

The effect of earthworm coprolites on the soil water retention curve

Eurasian Soil Science, 2008
The effect of earthworm coprolites on the water retention curves in soils of different geneses and textures was investigated by the method of equilibrium centrifuging. Coprolites sampled in the field were com- pared with the surrounding soil. The effect of earthworms on a soddy-podzolic light loamy soil (from Moscow oblast) was comprehensively analyzed

Using the energy integral of soil water retention curve to evaluate the Soil water availability

2011 International Symposium on Water Resource and Environmental Protection, 2011
The Soil water availability (SWA) reflects the degree of difficulty that plant absorbs and utilizes soil moisture. However, these SWA indexes including static criterions and dynamic indexes are inconsistent and difficult to use practically. In this paper, we thought SWA actually reflected consumption energy value of uptake water by plant, and the ...

Pedotransfer functions for the soil water retention curve

2018
Pedotransfer functions allow prediction of the soil hydraulic characteristics from basic soil data. In this study pedotransfer functions were developed in order to obtain three specific points of the soil water retention curve: field capacity, wilting point and maximum capacity, which were considered to be correspondent to the water held in soil ...

Parameter estimation of the soil water retention curve model with Jaya algorithm

Computers and Electronics in Agriculture, 2018
Abstract Parameter estimation of the soil water retention curve model using Jaya algorithm is studied in this paper. Different from conventional heuristic search algorithms, Jaya algorithm is a swarm intelligence algorithm without algorithm-specific parameters.
