Stratigraphic architecture of fluvial fans shaped by downstream changes in avulsion style Open
Natural river diversion, or avulsion, controls the distribution of channels on a floodplain and channel sandstone bodies within fluvial stratigraphic architecture. Avulsions establish new flow paths and create channels through several reco…

Delft3d Barataria Basin Sediment Budget Results Open
These zip files contain results from Delft3D FlexMesh model runs that simulate overbank sedimentation in Barataria Basin from a flooding Mississippi River and Bayou Lafourche. There are two sets of simulations, the Predam_Simulations.zip c…

Morphodynamic limits to environmental signal propagation across landscapes and into strata Open
The sedimentary record contains unique information about landscape response to environmental forcing at timescales that far exceed landscape observations over human timescales. However, stochastic processes can overprint and shred evidence…

Quantifying environmental signal propagation and preservation in ancient sediment routing systems using field data Open
<p>The assertion that stratigraphy will store environmental signals, such as sediment flux signals related to paleoclimate and tectonics, is debatable because that same stratigraphy can also store signals of autogenic processes that …

A Stratigraphic Framework for the Preservation and Shredding of Environmental Signals Open
The stratigraphic record contains unique information about past landscapes and environmental change. Whether landscapes faithfully transmit signals of environmental change to stratigraphy is unknown because autogenic processes, such as riv…
