Grain-Shape Analysis of Littoral and Shelf Sands, Southern California
Estimation of the exchange rates and determination of transport mechanisms and pathways associated with the onshore-offshore vector is one of the greatest sources of error in sediment...
Beach Profiles vs. Cross-Shore Distributions of Sediment Grain Sizes
In the present paper, field results are reported from various tideless beaches in Greece with mixed sedimentary environments. The two classical beach profiles are examined in terms of...
Effect of Varying Sediment Size on Equilibrium Beach Profiles
Beach profiles from four field sites and accompanying data describing the cross-shore distribution of median sediment size are analyzed and compared to predicted profiles based on an equilibrium...
Longshore Transport of Pebbles: Experimental Estimates of K
Three tracer experiments which provide estimates of the coefficient of proportionality (K) for the longshore transport of pebbles in the CERC equation are reconsidered. The values are...
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...
Conglomeratic Shoreface Deposits from the Cretaceous Cardium Formation, Alberta, Canada
Conglomeratic shoreface deposits of the Upper Cretaceous Cardium Formation are well exposed at an outcrop in northwestern Alberta. The conglomerates there compose over 80% of the total...
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...
Problems with Predicting the Transport of Pumiceous Sediments in the Coastal Environment
Pumice is often a major component of coastal sediments associated with subduction zone volcanic settings. Several recent studies in New Zealand have highlighted the difficulties of predicting...
Geologic Framework and Depositional History of the Southeastern Texas Coast
Effective management of coastal resources and accurate prediction of future land losses are impeded by the lack of geologic framework investigations that link coastal processes with depositional...
Cyclonic Events and Sedimentation in the Gulf of Mexico
An ample literature exists documenting the destructive effects hurricanes have upon offshore barrier islands and coastlines. The Gulf of Mexico region has been especially heavily impacted...
The Oceanside Experimental Sand Bypass?The Next Step
Following the completion and successful operation of the first phase of the Oceanside Sand Bypass, the next step in the development of the experiment has begun. The Phase I plant is not...
Wave-Current Interaction at Wells Inlet, Maine
Wells Inlet is a jettied waterway along the southern coast of Maine. Since its initial structuring and dredging for harborage, the inlet has been plagued by severe shoaling. The jetties...
Processes of Sediment Transport and Ebb Tidal Delta Development at a Jettied Inlet
This paper deals with the development of the ebb tidal delta following the extension of jetties at a tidal river entrance. The growth rate and morphological change are discussed using...
Infragravity Wave Motion in a Tidal Inlet
Infragravity waves (20
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...
Thoughts on Large Scale Coastal Behavior
Large scale coastal behaviour (LSCB) deals with the development of coastal profiles and sediment budgets of a large coastal stretch (order tens of km's) over a considerable...
Regional Sediment Transport in the Coastal Boundary Layer of the Central Alaskan Beaufort Sea
The characteristics of regional sediment transport in the Central Alaskan Beaufort Sea Coastal Ocean are defined by sources, marine sediment dynamics, and areas of net sedimentation. These...
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...
Physical Modelling of Pocket Beaches
The design of artificial beach systems is dependent upon the modelling criteria and on the selection of the sand material to be used for nourishment. In order to obtain a stable beach...
Movable-Bed Model Study of Storm-Induced Beach Fill Erosion at Ocean City Maryland
Movable-bed physical model scaling guidance has recently been validated for the case of turbulent-dominated sediment transport, such as occurs in the surf zone. The tests successfully...
