An easily installable groundwater lysimeter to determine waterbalance components and hydraulic properties of peat soils [PDF]

open access: yesHydrology and Earth System Sciences, 2003
A simple method for the installation of groundwater lysimeters in peat soils was developed which reduces both time and financial effort significantly. The method was applied on several sites in the Rhinluch, a fen peat land 60 km northwest of Berlin,

Effect of Soil-Water Characteristic Curve on the Stability of Unsupported Vertical Trenches in Unsaturated Soils [PDF]

open access: yesE3S Web of Conferences, 2023
In geotechnical engineering practice, unsupported vertical trenches are typically excavated in unsaturated soils. In this case, the variation of shear strength and hydraulic conductivity with respect to soil suction is key information to analyze the ...

Closed‐form hydraulic conductivity equations for multimodal unsaturated soil hydraulic properties [PDF]

open access: yesVadose Zone Journal, 2021
Abstract Closed‐form expressions of the hydraulic conductivity function for linearly superposed subretention (multimodal) functions were derived for arbitrary sets of the Brooks and Corey (BC), van Genuchten (VG), and Kosugi (KO) water retention models.
