Improved model for predicting the hydraulic conductivity of soils based on the Kozeny–Carman equation

open access: yesHydrology Research, 2021
The saturated hydraulic conductivity of soils is a critical concept employed in basic calculation in the geotechnical engineering field. The Kozeny–Carman equation, as a well-known relationship between hydraulic conductivity and the properties of soils ...

Using X-ray micro CT imaging data to obtain particle morphology and soil fabric parameters [PDF]

open access: yesE3S Web of Conferences
In addition to the well-understood effects of void ratio and effective confining stress on the mechanical behavior of finegrained soils, past experimental research at the University of British Columbia (UBC), Vancouver, Canada, has revealed a ...

Thermoluminescence dating studies of rapidly deposited silts from south-central British Columbia

open access: yes, 1985
To determine whether Quaternary sediments from small lake and fan deposits can be dated by thermoluminescence (TL) methods, I have applied recently proposed techniques for TL dating to known-age, rapidly deposited silts and have examined the sensitivity
