A multi-proxy study of the Palaeocene - Eocene Thermal Maximum in northern Spain
… continental and marine sections within the same sediment routing system, and one of the first comparisons of the same OM proxies within different depositional environments. The data suggest that different OM pools were mobilised in response to the PETM, with reworking of older material, soil …

Multi-Disciplinary Analyses of Outcropping Late Cretaceous Clinoform Stratigraphy, Magallanes Basin, Chile
Shelf margins are critical transfer zones where sediment, organic matter, and associated fluids move from continents to deep-marine basins. Clinoforms, shelf-edge deltas, submarine canyons, and deep-water channels are central components of these systems, yet their stratigraphic architecture, …

Sedimentology and Architecture of a Partially Contained Deposit, Cerro Solitario, Magallanes Basin, Chilean Patagonia
The depositional styles of sediment gravity currents depend, in part, on the relationship of flow magnitude to the scale of topographically controlled containment and range from unconfined lobes to fully contained deposits. Determining the degree of containment is important for understanding …

Modeling the transport of sand and mud in the Minnesota River
… rivers is thought to be controlled by water and sediment supply, and characteristic sediment size. Here we demonstrate a novel finding: when bankfull shear velocity and bankfull depth are correlated against bed material grain size and bed slope, they are to first order independent of grain size …

Basin Evolution and Slope System Dynamics of the Cretaceous Magallanes Basin, Chilean Patagonia
… profiles commonlyhost the final accumulation of sediment that was eroded and transported from the continents. Thedeep-marine sediment archives preserved in these settings commonly offer the most completerecord of sediment transfer from continents to ocean basins over geologic time scales. This …

Multi-scale stratigraphic and statistical analysis of allogenic and autogenic controls on fluvial systems
… document how the autogenic morphodynamics of the sediment routing system control the planform shape of channel belts. Specifically, that the erosion coefficients of the subjacent and lateral material determine the final channel-belt morphology given long enough residence time on the floodplain. At …

Stratigraphic response to Cordilleran processes along the south central Andean margin
… rheology, deformation, and erodibility. The sedimentary record within convergent systems provide a unique opportunity to understand long-lived Cordilleran processes between subduction, magmatism, erosion, sediment routing, and deposition. This dissertation investigates the Phanerozoic to …

Multi-scale deep-marine stratigraphic expressions in the Cretaceous Magallanes Basin, Chile: Implications for depositional architecture and basin evolution
… one of the most significant features of sediment transfer on Earth and one of the final segments in source-to-sink routing systems. As such, they serve as conduits as well as intermediate or final storage for large volumes of sediment, paleoenvironmental signals, and pollutants on their …

Managing complexity in high-concentration flow modelling aimed at hazard assessment: numerical and practical aspects
… they are free-surface flows with intense sediment transport, often caused by intense rainfall events and involving large volumes of solid material. Because of the amount of sediments moved, the intense erosion and deposition processes typically observed and the quite unexpected character, …

Experimental study of reservoir turbidity currents venting
… of their performance is threatened by sediment deposition within the impoundment. To achieve long-term sustainable performance of reservoirs, and to reach effective sediment management techniques, it is necessary to understand the characteristics of sediment and how it behaves before, …

Tectonic and climatic control on the evolution of the Himalayan mountain front
… of mass within an orogen may lead to transient sediment storage, which in turn might affect the state of stress and the level of fault activity. Distinguishing between different forcing mechanisms causing variations of sediment flux and tectonic activity, is therefore one of the most challenging …
