Terminal fall velocity: the legacy of Stokes from the perspective of fluvial hydraulics

open access: yesProceedings of the Royal Society A, 2019
This review article, dedicated to the bicentenary celebration of Sir George Gabriel Stokes' birthday, presents the state-of-the-science of terminal fall velocity, highlighting his rich legacy from the perspective of fluvial hydraulics.

Fluvial sediment transfer in the Changjiang (Yangtze) river-estuary depositional system

open access: yesJournal of Hydrology, 2018
Knowledge of the transfer of sediment through river systems is essential for understanding the physical, chemical and biological processes on the Earth’s surface.

River discharge variability as the link between climate and fluvial fan formation

open access: yesGeology, 2020
There are two contrasting hypotheses on whether fluvial fans need specific climate conditions to form. Deduction of climatic and tectonic signals from landscapes and the sedimentary record is a key aim in geology and geomorphology.

Evolution of a late triassic fluvial system, NW Libya [PDF]

open access: yes, 2007
Fluvial systems, channel sandbodies and valley fills have been widely studied and documented in the literature, with particular attention paid to their internal structures.

Influence of catchment processes on fluvial morphology and river habitats [PDF]

open access: yes, 2011
Fluvial morphology is conditioned by three basic elements: flow regime, sediment yield and valley characteristics. These elements are controlled by factors operating at different spatial and time scales, within and outside of the basin.

An unusual titanosaur axis from the Upper Cretaceous of Brazil and its significance for sauropod anatomy and systematics

open access: yesThe Anatomical Record, EarlyView.
Abstract The Upper Cretaceous São José do Rio Preto Formation (Bauru Group, southeastern Brazil) has yielded a fragmentary but taxonomically diverse record of titanosaur sauropods, although elements from cervical series remain scarce. Here, we describe a nearly complete sauropod axis from the Vila Ventura Paleontological Area, representing an uncommon ...

Extreme Coastal Water Levels Exacerbate Fluvial Flood Hazards in Northwestern Europe

open access: yesScientific Reports, 2019
Compound flooding, such as the co-occurrence of fluvial floods and extreme coastal water levels (CWL), may lead to significant impacts in densely-populated Low Elevation Coastal Zones. They may overstrain disaster management owing to the co-occurrence of

Retention of dissolved silica within the fluvial system of the conterminous USA

open access: yes, 2013
Dissolved silica (DSi) is an important nutrient in aquatic ecosystems. Increased DSi retention within the fluvial system due to damming and eutrophication has led to a decrease in DSi exports to coastal waters, which can have severe consequences for ...

A new species of Lonchidiidae (Hybodontiformes) from the Late Jurassic of Brazil (Aliança Formation, Jatobá Basin)

open access: yesThe Anatomical Record, EarlyView.
Abstract The Aliança Formation (Jatobá Basin) represents lacustrine deposits formed in oxygenated waters that hosted a diverse fauna, including Hybodontiform sharks. Within this group, the Family Lonchidiidae comprises 11 valid genera, with Parvodus previously reported in Brazilian deposits from the Brejo Santo Formation (Araripe Basin, Late Jurassic ...

Critical dependence of morphodynamic models of fluvial and tidal systems on empirical downslope sediment transport [PDF]

open access: yes, 2019
The morphological development of fluvial and tidal systems is forecast more and more frequently by models in scientific and engineering studies for decision making regarding climate change mitigation, flood control, navigation and engineering works ...
