Decimeter-scale in situ mapping of modern cross-bedded dune deposits using parametric echo sounding : a new method for linking river processes and their deposits
(American Geophysical Union, 2013-08)
Collecting high-resolution data to quantify the sedimentary architecture within contemporary alluvial channels remains one of the outstanding challenges in fluvial sedimentology. Here, we present data collected using a ...
Condiciones Hidráulicas e Invertebrados Bentónicos en Cauces Fluviales con Fondo Arenoso. Influencia de la Hidrodinámica y Morfología de Dunas y MeandrosHydraulic Conditions and Benthic Invertebrates in Sandy Bed Fluvial Channels. Hydrodynamic and Morphology Influence of Dunes and Meander Bends
A review of Late Quaternary inland dune systems of South America east of the Andes
Inland dune systems of South America occur in a variety of environmental settings under different climatic conditions, from humid–subhumid to semiarid–arid. This contribution provides the state of the art on dune research ...
Morphology and flow fields of three-dimensional dunes, Rio Paraná, Argentina: Results from simultaneous multibeam echo sounding and acoustic Doppler current profiling
(Blackwell Publishing Ltd, 2005-12)
 Most past studies of river dune dynamics have concentrated on two-dimensional (2-D) bed forms, with constant heights and straight crest lines transverse to the flow, and their associated turbulent flow structure. This ...
Extremes in dune preservation: controls on the completeness of fluvial deposits
(Elsevier Science, 2015-09)
Understanding sedimentary preservation underpins our ability to interpret the ancient sedimentary record and reconstruct palaeoenvironments and palaeoclimates. Dune sets are ubiquitous in preserved river deposits and are ...
