TL;DR: In this article, a detailed field investigation conducted near an Australian native tree, Eucalyptus largiflorens, was described, which included field procedures such as drilling boreholes and taking soil samples, measuring the soil moisture content, soil suction, and also excavating trenches to observe the distribution of tree roots under the ground.

TL;DR: In this paper, the root-based suction of a tree improves the shear strength; accelerates the pore water pressure dissipation and it may alter the potential failure conditions of the soil-root system from a saturated to an unsaturated domain.

TL;DR: In this article, a permeable reactive barrier (PRB) was utilized to remediate the acidic water generated from acid sulfate soil (ASS) in the Shoalhaven Floodplain approximately 100 km south of Sydney, Australia, where acidic groundwater is a severe environmental, social, and economic problem.
