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 …

An outline of the inshore submarine geology of Southern South West Africa and Namaqualand
… Walvis Bay in South West Africa and the Olifants River mouth in Namaqualand, Republic of South Africa - a distance of approximately 1 000 km (600 miles). The area can be conveniently subdivided into three regions from north to south: (i) Tidal Diamond's Concession (T.D.C.) from Sandwich Harbour to …

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 …

Remotely operated vehicle exploring ichthyofauna association with habitat from shore-shelf, in an endemism hotspot in South Africa
… of these proposed MPAs is situated off the Kei river mouth in the Eastern Cape of South Africa. The area offshore of the Kei river mouth is an endemism hotspot, and a transitional zone between the Subtropical East Coast and the Warm Temperate South Coast. The region waslargely unexplored because …

Stratification on the Skagit Bay tidal flats
… On the south-central flats (near the south fork river mouth) velocities are roughly rectilinear, and the largest terms are in the major velocity direction (roughly cross-shore). However, on the north flats (near the north fork river mouth), velocity ellipses are nearly circular owing to strong …

The Effects of Basin Slope and Boundary Friction on the Character and Plunge Location of Hyperpycnal Flows Entering a Laterally Unbounded Basin
… on the behaviour of hyperpycnal plumes in river mouth discharges. The plunging of high density flows in two dimensional channels has been extensively studied before. A fundamental assumption in these studies is that the flow is laterally confined. These studies allow the flow to plunge only …

Assessing conservation of a tropical African estuary : waterbird disturbance, livelihoods, and ecotourism
… of increasing conservation in the Sabaki River Mouth Important Bird Area. This was achieved by assessing the vulnerability of waterbirds to disturbance from human activity in the estuary, the current use and importance of the area to local livelihoods, and the value (current and potential) …

Nearshore zooplankton communities of Lake Michigan and implications for invasibility by Asian carp
… such as Green Bay and Michigan drowned river mouth lakes, while smaller-bodied zooplankton constituted the majority of biomass in open water and harbor locations with lower primary production. These biomass estimates, in turn, affected predicted Asian carp growth rates. Negative growth …

The interaction of two coastal plumes and its effect on the transport of Alexandrium fundyense
… understanding of the interactions between river plumes is essential to our understanding of this problem. The rest of this thesis intends to contribute to the understanding of these plume interactions and their effect on the transport of A. fundyense. Mixing between two interacting river …

Tangimoana Regional Park : Site and recreation potential analysis : This study was prepared as a partial requirement of the Diploma in Parks and Recreation [Lincoln College]
… the strip between the Manawatu andTurakino rivers was regarded as being the most acceptable for coastal recreation, and within this area the Rangitikei river mouth and adjacent land offers the greatest potential of a regional nature. Objectives The objective of this study is to:- 1. Examine …

A quantitative comparison of the Howiesons Poort lithic assemblage from Kathu Pan 6 in the Northern Cape with other Howiesons Poort assemblages in Southern Africa
… other sites, namely Klipdrift Shelter, Klasies River Mouth, and Pinnacle Point 5-6, will allow me to characterize geographical variability in the HP and identify possible explanations for this variability, including different foraging and mobility strategies in different environments across …

Dynamics of freshwater plumes: observations and numerical modeling of the wind-forced response and alongshore freshwater transport
A freshwater plume often forms when a river or an estuary discharges water onto the continental shelf. Freshwater plumes are ubiquitous features of the coastal ocean and usually leave a striking signature in the coastal hydrography. The present study combines both hydrographic data and idealized …

Channel Processes and form Near the Tidal Limit
<p>Coastal plain river flow is driven by the topographic gradient unless acted on by marine tides. Where sufficiently strong tides occur, a tidal wave will enter the river mouth and advance upstream until it dissipates due to bottom friction and downstream flow. It follows that near the upstream …
