A Study of the Impact of the Dumping of Spoil on Beach Processes
The amenity value of beaches along the North East coast of England is reduced because of the continuing practice of dumping colliery spoil directly onto the beaches for dispersal by the...
Coastal Erosion in Ghana: Causes, Patterns, Research Needs and Possible Solutions
The pattern of coastal erosion in Ghana is described. The causes for spatial differences in the erosional rates on the shoreline are identified as coming from a combination of natural...
Sediment Transport in the Swash Due to Obliquely Incident Wind-Waves Modulated by Infragravity Waves
Swash is described by obliquely incident wind-waves superposed on, and interacting with, long standing waves. The wind waves of the inner surf zone are modulated in amplitude, wavenumber...
Critical Examination of Longshore Transport Rate Magnitude
Inconsistencies in the field data and predictions of longshore sediment transport (LST) rates associated with the CERC and Bagnold formulae are discussed. Practical errors in direct application...
Longshore Sand Transport Rate Distributions Measured in Lake Michigan
Cross-shore and vertical distributions of longshore sand transport in the nearshore zone were measured in a field data collection project conducted at Ludington, Michigan, on the east...
Relationship Between Longshore and Cross-Shore Transport
Radiation stress principles are shown to control both longshore and cross-shore wave induced stresses which in turn determine the major processes controlling sediment transport. Recent...
A Calibrated Longshore Transport Model for Richards Bay
In order to plan maintenance dredging at the Port of Richards Bay, different studies were carried out. These were to determine the extreme dredging rates required in the long term and...
Neashore Sediment Transport by Slush/Brash Ice in Southern Lake Michigan
Bands of mobile ice are common features in the Great Lakes nearshore zone during the winter months. Samples were collected during December, 1989 to determine the sediment content in the...
Littoral Dune Transport and Morphology Under a Variable Wind Regime
Most of the large dunes are generally produced by a permanent or quasi-permanent winds. Usually winds present strong concentrations of its directional spectrum around its mean direction....
Mean Currents and Sediment Transport at DELILAH
Bailard's sediment transport model (1981) is used as a framework to test the hypothesis that mean currents can dominate nearshore sediment transport. The data acquired during...
Sedimentation Processes in Morro Bay, California
A series of field investigations and historical data analyses were conducted to determine historical sedimentation processes in Morro Bay, California. Three sources of sediment were identified:...
The Sedimentary Organisation and Behaviour of Drift-Aligned Gravel Barriers
Drift-aligned barriers formed of coarse clastic materials and described in terms of their organisational evolution at two levels, a) sorting and selection of clasts; b) development of...
Gravel Spit Stabilized by Unusual(?) High-Energy Wave Climate in Bay Side, Tierra Del Fuego
A 17 km-long sand and gravel spit grew from the Atlantic coast of Tierra del Fuego in the late Holocene, semi-enclosing a large and deep embayment. Strong westerly winds generate high-energy...
Observations of a Tidal Inlet on a Shingle Beach
An observation and measurement program was undertaken at Batiquitos Lagoon, San Diego County, California to better understand the paths and rates of shingle movement in the littoral zone....
Net Late Holocene Emergence Despite Earthquake-Induced Submergence, South-Central Chile
Intertidal deposits show net late Holocene emergence along the Pacific coast near Maullin and Carelmapu, Chile (latitude 41.6°-41.7°S). The maximum amount of net emergence is about 1 m...
Historical Coastal Morphodynamics at St. Marys Entrance and Vicinity, Florida, U.S.A.
St. Marys Entrance is an Atlantic Ocean tidal inlel located on the Florida-Georgia state border. At the end of the nineteenth century rubble-mound jetties were constructed. Large-scale...
Sorting Characteristics of Tidal Inlets
An hypothesis is presented as follows: Littoral processes at a tidal inlet remove a disproportionately higher quantity of fine grain sediment than coarse grain sediment from the littoral...
Regional Beach Sand Volumes of the Pacific Northwest, USA
Eight small littoral cells ranging from 5-60 km in length have been surveyed by beach profiling and seismic refraction to establish active beach sand volumes in the Pacific Northwest region....
Large-Scale Coastal Evolution of Louisiana's Barrier Islands
The prediction of large-scale coastal change is an extremely important, but distant goal. Here we describe some of our initial efforts in this direction, using historical bathymetric information...
Processes of Shoreline Change Along the Nile Delta Coast of Egypt
A comprehensive program has been underway for more than a decade to collect nearshore data related to erosion problems experienced along the shoreline of the Nile Delta. The data include...
