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...
Accurate Shoreline Mapping: Past, Present, and Future
Mapping historical shoreline changes and predicting future shoreline positions requires both accurate and precise analyses of time-dependent fluctuations in water levels and sediment volumes...
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...
Late Quaternary Geologic Framework, North-Central Gulf of Mexico
The geologic framework of the north-central Gulf of Mexico shelf is composed of multiple, stacked, delta systems. Shelf and nearshore sedimentary facies were deposited by deltaic progradation,...
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...
Optimization of Maintenance for Coastal Inlets with Uncertainty
Maintenance dredging costs the nation roughly $400 million per year. Yet, relative to other areas of water resources engineering, little attempt has been made to apply operations research...
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...
Eustatic and Neotectonic Controls on Salt Marsh Sedimentation
This paper presents a revised conceptual model of the long-term evolution of back-barrier marshes on the macro-tidal north Norfolk coast and their adjustment to tidal levels. The present...
Response of Lagoons to Sea Level Change
Relative sea level change and sediment accumulation rates are compared for 21 lagoons on the U.S. Atlantic and Gulf coasts to determine their accretionary status. The lagoons reviewed...
Preservation Potential of the Delaware Atlantic Coast Barrier?Backbarrier System
Volumes of Delaware Atlantic barrier and shoreface lithosomes were digitized to evaluate preservation potential during transgression. Erosion during headland retreat of less than 0.5 km...
The Stratigraphic Record of Oxygen Isotope Stage 5 on the Maryland Inner Shelf
Present knowledge of Holocene transgressive coastal/shelf systems, while extensive, cannot directly address the effects and consequences of an extended period of relatively high sea levels...
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...
Historical Morphologic Evolution and Sedimentation at Barataria Pass, Louisiana
Barataria Pass, Louisiana, one of the most commercially important tidal inlets in the Gulf of Mexico, has undergone several stages of development since 1840. The shore-parallel growth...
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...
Erosion and Accretion Along the Arctic Coast of Alaska: The Influence of Ice and Climate
Coastline comparison on 1951 and 1981 charts to determine erosion and accretion showed that ocean-facing coastal bluffs were retreating while deltas were rapidly expanding. Where the coast...
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...
