An experimental study of the relationship between water content and strength of unsaturated expansive soil on canal slope

Shuiwen dizhi gongcheng dizhi, 2022
The soil layer in the canal first section of the Middle Route of the South-to-North Water Transfer Project (MR-SNWTP) is mainly composed of expansive soil, and changes in water content of the expansive soil affect the stability of the slope.

Infrared Drying for Water Content Measurements of Soils

Geotechnical Testing Journal, 2023
Abstract The water content of soils is frequently needed, and its reference value is currently obtained by conventional convection ovens. Infrared (IR) ovens appear to be overlooked by the geotechnical community even though they allow for precise control over temperature, much faster heat transfer, and much better energy efficiency ...

Soil water-balance-based approach for estimating percolation with lysimeter and in field with and without mulch under micro irrigation

Revista Ambiente & Água, 2021
Precise, accurate knowledge of percolation is key to reliable determination of soil water balance and a crop’s water-use efficiency. This work evaluated an approach to estimate the amount of water percolated in the root zone using soil water content (SWC)

Soil water regime estimated from the soil water storage monitored in time

Soil and Water Research, 2008
During the vegetation season, the water storage in the soil aeration zone is influenced by meteorological phenomena and by the vegetated cover. If the groundwater table is in contact with the soil profile, its contribution to water storage must be ...
