Relay ramps as pathways for turbidity currents: a study combining analogue sandbox experiments and numerical flow simulations

Unlike for subaerial settings, the impact of subaqueous relay ramps on sediment dispersal is still poorly understood. A combination of analogue laboratory experiments in a sandbox with numerical flow calculations is used to simulate relay ramp topographies on rifting continental margins and to analyse the resulting turbidity current pathways and their deposits. Various scenarios are investigated, including inflow perpendicular and oblique to the relay ramp axis as well as flow constrained by an incised channel on the ramp and by a landward‐directed tilt of the ramp. Without channelling, most sedimentation takes place on the basin floor because the bulk of the flow follows the steepest gradient down the fault and into the rift basin. With a channel along the relay ramp, significant flow occurs initially down the ramp axis, but channel spillover and basinward ramp tilting combine to redirect much of the sediment down the fault slope into the basin. When the relay ramp has a landward‐oriented tilt, most of the current flows down the ramp and deposits its sediment load there and at the foot of the ramp. However, also here a considerable amount of the flow is shed over the hanging wall fault and into the basin, forming a secondary depocentre, while ponding redistributes thin deposits over a wider area of the basin. The quantitative dependence of these results on the specific ramp geometries remains to be investigated further but may bear great importance for refined sedimentary models in subaqueous rifted settings as well as for hydrocarbon exploration therein.

“…The model was verified by comparison with experimental data for turbidity currents driven by uniform and non-uniform sediment. Groenenberg (2007Groenenberg ( , 2009) developed a 2D model that used a combination of the explicit fractional-step MacCormack scheme with a high-resolution shock-capturing technique. The model is solved numerically on a rectangular grid by means of a second-order finite-difference approximation.…”

Modeling of Turbidity Current and Evaluation of Diversion Plans at Shihmen Reservoir in Taiwan

Turbidity currents occur often at Shihmen reservoir in Taiwan that has experienced increased sediment delivery over the last two decades. Due to limited sluicing capability, a major portion of the fine sediments has deposited in the reservoir causing a significant loss of the storage capacity. Further, extreme events had produced such high sediment concentrations that water supply has been interrupted causing unexpected economic and political turmoil. Various projects have been proposed and/or started in order to extend the reservoir life and maintain water supply. In this study, a two-dimensional (2D) layer-averaged turbidity current model is developed; the calibration and application of the numerical model to Shihmen reservoir is reported. The study finds that the developed turbidity current model, with appropriate calibration, predicts well the turbidity current movement and the sediment deposition pattern.

A Gradually Varied Approach to Model Turbidity Currents in Submarine Channels

2018

We develop a one‐dimensional model to describe the dynamics of turbidity current flowing in submarine channels. We consider the flow as a steady state polydisperse suspension accounting for water detrainment from the clear water‐turbid interface, for spatial variations of the channel width and for water and sediment lateral overspill from the channel levees. Moreover, we account for sediment exchange with the bed extending the model to deal with situations where the current meets a nonerodible bed. Results show that when water detrainment is accounted for, the flow thickness becomes approximately constant proceeding downstream. Similarly, in the presence of channel levees, the flow tends to adjust to channel relief through the lateral loss of water and sediment. As more mud is spilled above the levees relative to sand, the flow becomes more sand rich proceeding downstream when lateral overspill is present. Velocity and flow thickness predicted by the model are then validated by showing good agreement with laboratory observations. Finally, the model is applied to the Monterey Canyon bathymetric data matching satisfactorily the December 2002 event field measurements and predicting a runout length consistent with observations.
