Scale-dependent perspectives on the geomorphology and evolution of beach-dune systems

IJ Walker, RGD Davidson-Arnott, BO Bauer… - Earth-Science …, 2017 - Elsevier
Despite widespread recognition that landforms are complex Earth systems with process-
response linkages that span temporal scales from seconds to millennia and spatial scales …

A review of the application of the fetch effect to modelling sand supply to coastal foredunes

I Delgado-Fernandez - Aeolian Research, 2010 - Elsevier
The fetch effect is an increase of the aeolian sediment transport rate with distance downwind
over an erodible surface. The first observations of the fetch effect go back 70years and the …

Meso-scale aeolian sediment input to coastal dunes: The nature of aeolian transport events

I Delgado-Fernandez, R Davidson-Arnott - Geomorphology, 2011 - Elsevier
Observations of aeolian transport in coastal areas have focused on short-term experiments
because of limitations imposed by instrumentation. This paper uses a case study at …

Aeolian sand strip mobility and protodune development on a drying beach: examining surface moisture and surface roughness patterns measured by terrestrial laser …

JM Nield, GFS Wiggs… - Earth Surface Processes …, 2011 - Wiley Online Library
Ephemeral aeolian sand strips are commonplace on beaches. Their formation during high
energy sand transport events often precedes the development of protodunes and their …

Controls on the geomorphic response of beach-dune systems to water level rise

RGD Davidson-Arnott, BO Bauer - Journal of Great Lakes Research, 2021 - Elsevier
This paper offers a synthesis of the disparate evidence on the importance of the magnitude
and duration of water level rise in both lacustrine and marine environments in relation to …

Measuring and modeling the effect of surface moisture on the spectral reflectance of coastal beach sand

C Nolet, A Poortinga, P Roosjen, H Bartholomeus… - PloS one, 2014 - journals.plos.org
Surface moisture is an important supply limiting factor for aeolian sand transport, which is
the primary driver of coastal dune development. As such, it is critical to account for the …

Annual to decadal morphodynamics of the foredune system at Greenwich Dunes, Prince Edward Island, Canada

J Ollerhead, R Davidson‐Arnott… - Earth Surface …, 2013 - Wiley Online Library
The purpose of this study was to quantify relationships between season, sediment
availability, sediment transport pathways, and beach/foredune morphology at Greenwich …

Flow deflection over a foredune

PA Hesp, TAG Smyth, P Nielsen, IJ Walker, BO Bauer… - Geomorphology, 2015 - Elsevier
Flow deflection of surface winds is common across coastal foredunes and blowouts. Incident
winds approaching obliquely to the dune toe and crestline tend to be deflected towards a …

High‐frequency sediment transport responses on a vegetated foredune

RGD Davidson‐Arnott, BO Bauer… - Earth Surface …, 2012 - Wiley Online Library
Wind flow and sand transport intensity were measured on the seaward slope of a vegetated
foredune during a 16 h storm using an array of sonic anemometers and Wenglor laser …

Meso-scale modelling of aeolian sediment input to coastal dunes

I Delgado-Fernandez - Geomorphology, 2011 - Elsevier
The collection of a time series coupling hourly wind data (speed and direction) with sand
transport over months has provided new insights into the dynamics of transport events that …
