Hydrodynamics, sediment transport and morphodynamics at inlets and river mouths: a numerical investigation
Inlets and river mouths are among the most important coastal zones in terms of their economic, ecological and societal values. However, our current predictive capability on the hydrodynamics, sediment delivery and morphological evolution of inlets and river mouths remains qualitative. The …

IMPACTS OF RIVER INFLUENCE AND WAVE EXPOSURE ON THE EPIPSAMMIC DIATOMS OF THE LAKE SUPERIOR WAVE ZONE
… are linked with these wave zones through river mouth habitats, which provide nutrient and organismal input to lake systems. In this study, I assessed the abundance, productivity, and community composition of epipsammic diatoms in river mouth and beach habitats along the south-central coast …

The sediment, river plume, and inner shelf variability in a bay with multiple fluvial inputs
Small mountainous rivers deliver considerable sediment loading to the coastal ocean and play a disproportionate role in marine sediment deposition globally. Discharge in these rivers is often driven by short episodic events and they typically deliver sediment to energetic coastal environments where …

Plan-view evolution of wave-dominated deltas
… shape deltaic landforms and how small scale river mouth processes affect large-scale delta morphology. I have developed and applied models of plan-view delta shape and their channel dynamics. Simple parameterizations and key insights from these models have allowed us to transcend spatial …

MULTISPECIES USE OF VARIOUS HABITATS IN THE MISSISSIPPI SOUND WITH AN EMPHASIS ON FUTURE OYSTER REEF CONSTRUCTION
… with sandy habitats nearest to bay or river mouths having high transient fish use. Oyster reef construction in these areas is likely to influence transient fish, but the benefit or detriment of the reef depends on the sub-habitats provided. Transient fish have high economic value and …

Factors influencing the nursery dynamics of juvenile bull sharks in two estuaries along the Texas coast
… sharks were highest in low salinity waters near river mouths, and in San Antonio Bay, lower predation risk was a significant factor predicting densities of YOY bull sharks. YOY bull shark densities were also influenced by temperature, dissolved oxygen, and location within the estuary. …

Semi-quantitative evaluation of river landscapes in the counties of Glamorgan
… This study selected one method specific to rivers and investigated the eight largest river basins of Glamorgan, South Wales, ie the Rivers Rhymney, Taff, Ely, Thaw, Ogmore, Afan, Neath and Tawe. Analysis of an adapted 46 factor checklist data from the 141 sites studied on the Glamorgan River …

A trace element study of sediments from the Olifants River estuary, the Berg River estuary, and the off-shore Mud Belt
… of trace elements for the Olifants and Berg river catchments by focusing on the sediments of the estuaries. The dominant industry in both catchments is agriculture and there exists relatively little urban sprawl. Two sediment samples taken from the offshore mud belt in the vicinity of the two …

Glaciological investigations in east greenland using digital landsat imagery
… in the vicinity of tidewater termini and river mouths were identified using MSS band 1 data (0.5 to 0.6 ?m). These are interpreted to be turbid meltwater plumes, and this conclusion is supported by comparison with photographs from the field. Meltwater plumes are an important mechanism for …

Modelling animal movement in heterogeneous environments: from statistical inferential models to individual-based models
… bathymetry, and proximity to coastlines and river mouths. Addition of k-means clustering extends the utility of behavioural change point analysis, by providing a simple means through which the behaviours inferred for the location observations comprising individual movement trajectories can be …

The biogeography and trophic roles of coastal marine sponges (Porifera) from the west coast of the North Island, New Zealand: Influences of catchments.
… diversity, abundance, and uniqueness. Potential drivers for this biogeographic patchiness are addressed in subsequent sections of the research program. Environmental factors influencing the distribution and abundance of marine sponges as described around the Taranaki region (Waitara reefs, …
