Turbidity current sediment waves on irregular slopes: observations from the Orinoco sediment–wave field

Highstand vs. lowstand turbidite system growth in the Makran active margin: Imprints of high-frequency external controls on sediment delivery mechanisms to deep water systems

“…As it is distinctively observed in the adjacent NIOP-472 and KS21 cores (Fig. 5), we suggest that topographically induced autogenic processes such as local flow velocity increase and decrease or local confinement preclude a definitive allogenic facies change in this environment (Migeon et al, 2001;Ercilla et al, 2002).…”

The tributary valley systems of the Almeria Canyon (Alboran Sea, SW Mediterranean): Sedimentary architecture

“…The presence of levees is related to changes in the characteristics of the channelized turbidity currents, which may be the result of variations in the slope gradient. Where the gradient is reduced, the flow suffers a hydraulic jump with the subsequent increase in the flow thickness and decrease in the flow velocity (Komar, 1971;Garcia and Parker, 1989;Mulder and Alexander, 2001;Ercilla et al, 2002). As the flow thickness exceeds the depth of the valley, the flow overspills and deposits the finer sediments forming the levees along the margins.…”

The influence of dunes on mixing in a migrating salt‐wedge: Fraser River estuary, Canada

“…On the basis of these estimates, a Seavalley turbidity current would plot in the supercritical region of Figure 4 and would thus likely affect mixing in a similar fashion to the dunes we document herein in the estuarine salt-wedge. Similar calculations can be made for unconfi ned turbidity currents and an associated sediment wave fi eld in the submarine Orinoco Valley (Ercilla et al, 2002). Estimates by Ercilla et al (2002) …”
