Fostering Peat Moss Feedbacks to Accelerate Peatland Restoration
Alternative stable states and peat moss and vascular plant feedbacks in peatlands. Selected feedbacks in a peat moss‐dominated state or a vascular plant‐dominated state. The two insets show ecosystem states (dot) in resilience landscapes (bottom).

Frost heaving forces in Leda Clay
The frost heaving forces developed under a 1 ft (30.5 cm) diameter steel plate were measured in the field throughout one winter. The steel plate was fixed at the ground surface with a rock-anchored reaction frame. Heave gauges and thermocouples were installed at various depths to determine the position and temperature of the active heaving zone.The ...

Evaluate H2RI Wicking Fabric for Pavement Application - Year 2 [PDF]
The Tencate H2Ri wicking fabric has proven to work well on two roadway sections on the Dalton Highway. In each the fabric has reduced the water content in the embankment resulting in a maintenance free section.

Confinement effects in premelting dynamics
We examine the effects of confinement on the dynamics of premelted films driven by thermomolecular pressure gradients. Our approach is to modify a well-studied setting in which the thermomolecular pressure gradient is driven by a temperature gradient ...

Frost heave model calculations for the Calgary frost heave test facility
Frost heave calculations using the Segregation Potential (SP) model and the Incremental Ice Segregation (DISR) model are compared ta the observed frost heave data from chilled pipeline sections at the Calgary Frost Heave Test Facility. Madel calculations are performed with the measured temperature gradients and measured frost depths for a range of SP ...
