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,...
Processes Controlling the Retreat of the Isles Dernieres, A Louisiana Barrier-Island Chain
The Isles Dernieres is a low-lying, transgressive barrier-island chain situated about 150 km west of the modern Mississippi delta. Much of the Isles Dernieres consists of highly dissected...
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...
Morphodynamics of the Isles Dernieres Barrier Shoreline, Louisiana: 1984?1989
An aerial videotape mapping system was used to monitor spatial and temporal variability of the coastal morphology along the Isles Dernieres barrier shoreline. Between 1984 and 1989, nine...
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...
Sand Bypassing at Indian River Inlet, Delaware
To solve a beach erosion problem north of Indian River Inlet, Delaware, the US Army Corps of Engineers Philadelphia District and the State of Delaware have constructed a fixed plant sand...
Short-Term Characteristics of Coastal Lagoon Entrances in California
Methods of predicting the frequency of lagoon opening conditions and the cross-sectional area of the inlet channel are reviewed. The potential variation from these empirical relations...
Implications of Accelerated Sea-Level Rise on Louisiana Coastal Environments
Natural and human-induced processes have combined to produce high rates of relative sea-level rise and coastal land loss in Louisiana. This paper presents historical trends in sea-level...
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...
Effects of Sea Level Rise on the Mississippi River Delta Plain
Geologic studies of the Mississippi River delta plain and continental shelf reveal the occurrence of several relative sea level stillstands during the last stages of the Holocene transgression....
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...
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...
Late Quaternary (Pre-Holocene) Coastal Systems of New Jersey
The coastline and the area adjacent to the present shoreline of New Jersey has not been explored as intensely as the same region of neighboring states for pre-Holocene high sea level stillstands....
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...
Migrating East Australian Barriers and Reefs Under Greenhouse Scenario
Geological evidence which bears directly on the question of human-induced sea-level change and migrating shorelines is difficult to find. If we could find an ancient analog of the rapid...
Geomorphology and Sedimentation Patterns of Tidal Inlets: A Review
Tidal inlets are generally formed by either of two mechanisms: storm generated scour channels, and closure of estuarine entrances by growth of sand spits. On depositional, coastal plain...
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...
