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 …

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

Flow deflection over a foredune
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 …
