Tephra Transport, Sedimentation and Hazards
… processes that lead to tephra transport, sedimentation and hazards. In this study, and based on detailed mapping and sampling of the tephra deposit of the 2450 BP Plinian eruption of Pululagua volcano (Ecuador), I investigate tephra deposits through a variety of approaches, including …

Vegetative Response to Hurricane Sedimentation
… macrophyte Spartina alterniflora var. Loisel to sedimentation from Hurricanes Gustav and Ike. A range of sedimentation was used to track the above and belowground plant response, as well as the volume of mineral and organic matter, in the upper reaches of the marsh soil from September 2008 to …

Sedimentation in a stratified ambient
… We then report on layering arising from sedimentation in a density stratified ambient beneath an inclined wall.

Fluvial sedimentation in continental half-graben basins
The stratigraphic architecture of intracontinental rift basins is defined by a dynamic relationship between depositional belts associated with the basin floor and flanking tributary streams on the piedmont. Spatiotemporal distributions of these deposits are sensitive to basin geometry, subsidence …

Treatment of urban stormwater runoff by sedimentation
… degree of treatment that could be achieved by sedimentation of stormwater runoff. Seven runoff samples were collected from shopping centers, which were selected because of their large impermeable surfaces resulting in high pollutant concentrations. The sampling sites were also representative of …

Granger Lake Sedimentation and Watershed Conservation Implementation Assessment
Sedimentation rates for many Texas reservoirs may be skewed by overstated estimates of design capacity and assumptions perpetuated through subsequent volumetric surveys. Multi-frequency reservoir surveys offer the means by which we may improve existing reservoir data and validate historic …

Differential Sedimentation In A Mississippi River Crevasse Splay
In this study the patterns of sediment transport and deposition in the channels and receiving basin of a crevasse splay in the modern Mississippi River delta are examined, with emphasis on the development of a distributary mouth bar. Simultaneous hydroacoustic and optical measurements on the mouth …

Hydrodynamics of porous flocs in aggregation and sedimentation
… study investigates the role of aggregation and sedimentation in the fate and transport of particles and aggregates. Computational fluid dynamics modeling illustrates the significance of the hydrodynamics of porous aggregates on aggregation. Aggregation numerical modeling incorporating the porous …

Reservoir sedimentation in dryland catchments : modelling and management
… sediment management techniques, a reservoir sedimentation model is developed and coupled within the WASA-SED model, which simulates rainfall-runoff processes and sediment transport at the hillslope and river network. The reservoir sedimentation model consists of two modelling approaches, …

Multi phase numerical modelling of thickening and sedimentation
… non-flocculated particulate suspensions in batch sedimentation. The non-flocculated mode of the model is extended to predict the performance of a continuous gravity thickener. The various particle species within the particulate susepnsion are represented as separate phases with distinct …

Examining Coastal Marsh Sedimentation In Northeastern North Carolina
… berms allowed for more direct inundation and sedimentation. Deposition was varied temporally, but was generally dependent on wind events. Hurricanes provide enhanced deposition to the marsh, which aids in vertical marsh accretion. While shoreline erosion provided some sediment for vertical …

Sedimentation ponds and their operation in stormwater systems
The efficacy of sedimentation ponds as a means of sediment and heavy metal remediation is investigated, with particular regard to the physical and chemical conditions that may lead to remobilisation of metals from the sediments

Settling and sedimentation behavior of fine-grained materials
… phenomenon that often occurs during settling and sedimentation processes of finer materials. However, it has been regarded as a minor factor affecting settling process, e.g. settling velocity or consolidation rate. In this study, settling behaviors of talcs, kaolins and attapulgite were reviewed …

Bottom currents and abyssal sedimentation processes south of Iceland
An investigation was carried out to observe the geologic effects of steady bottom currents on sediments of East Katla Ridge on the southern insular rise of Iceland. Near-bottom southwest to west-flowing currents exceeded 20 cm sec-1 for two weeks over a 25-kilometer wide section of the ridge flank …
