Effects of basal debris on glacier flow
Glacier movement is resisted partially by debris, either within glaciers or under glaciers in
water-saturated layers. In experiments beneath a thick, sliding glacier, ice containing 2 to 11% …

Slow episodic shear of granular materials regulated by dilatant strengthening
PL Moore, NR Iverson - Geology, 2002 - pubs.geoscienceworld.org
Slow, stable shear of granular materials in landslides, beneath glaciers, and along fault
surfaces is common, despite little or no intrinsic strengthening of such materials with increasing …

Deformation of debris‐ice mixtures
PL Moore - Reviews of Geophysics, 2014 - Wiley Online Library
Mixtures of rock debris and ice are common in high‐latitude and high‐altitude environments
and are thought to be widespread elsewhere in our solar system. In the form of permafrost …

Geomorphological evolution of a debris‐covered glacier surface
There exists a need to advance our understanding of debris‐covered glacier surfaces over
relatively short timescales due to rapid, climatically induced areal expansion of debris cover …

Soft-bed experiments beneath Engabreen, Norway: regelation infiltration, basal slip and bed deformation
To avoid some of the limitations of studying soft-bed processes through boreholes, a prism
of simulated till (1.8 m × 1.6 m × 0.45 m) with extensive instrumentation was constructed in a …

Stability of supraglacial debris
PL Moore - Earth Surface Processes and Landforms, 2018 - Wiley Online Library
Rock debris on the surface of ablating glaciers is not static, and is often transported across
the ice surface as relief evolves during melt. This supraglacial debris transport has a strong …

Sediment and phosphorus contributions from eroding banks in a large intensively managed watershed in western Iowa, United States
FF Williams, PL Moore, JV Allen… - JAWRA Journal of …, 2024 - Wiley Online Library
In this study, a new remote sensing tool was used in conjunction with sampling of river bank
sediments to map channel migration patterns and estimate the net contribution of bank …

Conditions for thrust faulting in a glacier
Dipping, arcuate bands of debris‐rich ice outcropping near the margins of glaciers are often
interpreted as thrust faults, assumed to originate in zones of longitudinal compression. …

[HTML][HTML] Numerical simulation of supraglacial debris mobility: implications for ablation and landform genesis
PL Moore - Frontiers in Earth Science, 2021 - frontiersin.org
Supraglacial debris does not remain fixed atop ablating ice, but can move across the ice
surface as supraglacial topography evolves. This active debris movement (distinct from passive …

Changes in lateral floodplain connectivity accompanying stream channel evolution: Implications for sediment and nutrient budgets
Floodplain storage commonly represents one of the largest sediment fluxes within sediment
budgets. In watersheds responding to large scale disturbance, floodplain-channel lateral …
