▼ External controls such as glacio-eustatic sea-level variation are known to have a strong influence on the areas of deposition and erosion, thereby affecting the location of channels, as well as their stacking patterns. Recent studies have shown that paleo-environmental (allogenic) signals preserved in stratigraphy may be overprinted by internally generated (autogenic) sedimentation. However, it is unclear to what affects external controls, such as sea-level change, subsidence, but also sediment mixture may have on the time scale over which there is a transition between allogenic and autogenic stratigraphy. Two sets of experiments were carried out in the Eurotank Flume Laboratory at
Utrecht University during which the morphology and the topography of the fluvial system were regularly monitored to determine compensational stacking. Using statistical methods, basin filling trends were quantified. The compensation index (σss) and the compensation time scale (κn) were used to explore how compensation, the tendency for sediment transport to preferentially fill topographic lows, varies over the basin´s length. The observed compensation time scale, which was defined as the break in the basin-filling trend, varies depending on whether there are any sea-level changes. The time scale at which the fluvial system becomes fully compensated will decrease from source to sink with no sea-level change, but increase during sea-level fall. Understanding channel migration and the resulting channel stacking patterns is important as it provides additional insight in deltas as hydrocarbon reservoirs, and enables further study as to how deltas and continental margins prograde.

▼ Recent years have experienced a bloom in 2D analogue flume modeling, due to the clear and simplified representation it gives on sedimentary systems. The difference in spatial and temporal scales between delta and shelf clinoforms has often been disregarded in those experiments. Furtermore, both the shelf and the delta topsets have been approached as a static entity, rather than a dynamic transit system. Longitudinal profiles from both experimental and real world data sets show however, that characteristic slopes fluctuate with time. A set of simple experiments was conducted in a 2D flume, at the Eurotank Flume Laboratory, at
Utrecht University. The experiments allow detailed observation of clinoform response to allogenic forcing, i.e. changes in sediment supply and base level. Changes applied with different frequencies indicate that the spatial scale of the system, dictates its sensitivity to changes applied at the time scales. Secondly, the system was able to change the gradient of the alluvial system with sea level change as sole driving mechanism. Changes observed in topset slope caused by sea level change are approximately 3 times larger than the changes produced by sediment supply. Comparison of the presented flume data, show that it is in agreement with data from large scale Quaternary alluvial systems.

▼ An experimental approach of turbidity currents is presented in order to relate the internal composition of bounding levees based on their particle size with the turbidity current responsible for its formation and how various conditions influence both their structures. It is shown that turbidity currents internal structure, mainly its concentration profile/particle size profile, is significantly altered by changes in boundary conditions e.g. angle of slope and initial sediment composition. Furthermore experiments show three stages in the formation of submarine levees. 1) A coarse steeply fining upward frontal lobe. 2) A well-mixed broad levee only slightly fining upward relative equal in height as the body of the passing turbidity current. 3) A narrow steeply fining upward top section of the levee created from the highest layer and therefore finest particles of the turbidity current and its subsequent settling of particles during the waning stage.

▼ The flow dynamics of turbidity currents in relation to the resulting channel/levee morphology is still poorly understood. In a series of 3D flume experiments the evolution of a turbidite system will be studied in relation with the flow dynamics of high-density turbidity currents. These experiments were carried out in the Eurotank laboratory at the
Utrecht University. During the execution of the flume experiments the boundary parameters (concentration, sediment composition, discharge and slope gradient) were varied to explore which boundary settings are necessary to successfully simulate a turbidity system in the laboratory. Velocity profiles were obtained from the turbidity current during the experiment. Deposits were measured with a laser in order to study the morphology of channel and levees and to create digital elevation models of the deposits.
The results of the flume experiments show some similarities with natural turbidite systems but also some fundamental differences are present between overall sediment composition, sediment input orientation and lobe deposits. In future experiments these should be incorporated in order to achieve more realistic results. The results of the velocity profiles and laser scans conclude that confinement of the current is the main factor causing decreasing velocities outside the channel. An increasing channel gradient is the main factor causing increasing velocities inside the channel. Channel formation was initiated by deposition which lead to channelization of the turbidity current and formation of a channel with accompanying levees. After channelization of the flow, velocities in the channel increase and incision in the channel increases. This leads to the transition from an depositional system towards an erosional/depositional system. The turbidite system created in this study started as a depositional system. This is in contradiction with suggestions of Maier et al. (2013) and others (e.g. Campion et al., 2000; Gardner & Borer, 2000; Schwarz & Arnott, 2007; McHarue et al., 2011) which state that such systems do not exist. Results of the backslope of one of the levees are in good agreement with previous flume experiments and natural turbidite systems.

▼ The Aptian succession of the Vocontian paleomargin (SE France) consists of marl-prone mass transport deposits, turbidite sandstone and pelagic marl. A detailed stratigraphic framework, which was established by previous workers, allows correlation of individual event beds for up to 80 kilometres in the down-dip direction. One thick-bedded turbidite sandstone that is interbedded between two mass transport deposits is studied in several outcrops. The thickness of this sandstone bed is very variable. This paper aims to reconstruct the origin of these thickness variations. Detailed outcrop descriptions, with a focus on the nature of the contact of the turbidite with the underlying and overlying mass transport deposits, are presented. Multiple origins for sandstone thickness variation are recognised. Loading and injection are restricted to a relatively small scale and have only resulted in minor sandstone thickness variations. Infill of mass transport related topography acted on a much wider range of scales and resulted in thickness variations with an amplitude of up to ten meters. The elevated topography at the surface of the mass transport deposits is associated with compressional deformation zones within these deposits. The inference that the geometry a turbiditic sandstone is, to a large extend, controlled by the surface morphology of mass transport deposits is contrasting an earlier interpretation, in which the heterogeneity was attributed to the presence of multiple parallel turbidite channels. This reinterpretation yields that the planform geometry of the sandstone may be different than previously thought. Several types of field data that indicate directly that surface topography, created by mass transport deposits, indeed affected the flow dynamics of turbidity currents. A scour hole upstream of an obstruction indicates that erosion by turbidity currents was locally enhanced. Deviating flute directions on the flanks of obstructions indicates that flows were deflected.

▼ Both open-channel flows and density currents are able to create supercritical-flow bedforms. The
morphodynamics of these supercritical-flow bedforms are, however, still poorly understood. This is
mainly due to a lack of measurements of flow processes occurring within these types of flows. Cyclic
steps have successfully been simulated in open-channel flow using a depth-resolved numerical
model. The equilibrium conditions at which certain supercritical-flow bedforms are stable are
investigated. The temporal variation in Froude number is indicative of at which conditions cyclic
steps are in a macroscopic equilibrium at a variability of grain sizes, discharges and sediment
concentrations. The depth-resolved model provides insight into the dynamic interaction between
velocity structure, shear stresses, and sediment concentrations within the flows and resulting erosion
and deposition patterns, which, in their turn affect the flow-properties again. The velocity structure
downstream of a hydraulic jump displays highest flow velocities near the bed, whilst lowest or even
negative velocities are located at the top of the flow, causing the flow to remain exerting shear
stresses on the bed even after the hydraulic jump. The sediment concentrations within the flow only
decrease after a 30 second, or half a meter lag, causing most of the deposition to take place at the
last two-thirds of subcritical region of the flow. The resulting depositional pattern consists of
upstream-dipping backset laminations deposited on the stoss-side of the bedform, cross-cut by the
erosive surface of the lee-side of the cyclic step, this interplay between erosion and deposition also
causes an upstream migration of the cyclic steps.
