Crevasses on the Lower Course of the Mississippi River
Before construction of artificial levees, crevasses were a common event along the Mississippi River. They directed sediment out of the main channel and reduced flood stage down river....
Evaluation of Dissolved Oxygen and Nutrient Trends in the Houston Ship Channel from Historical Statewide Monitoring Data
Dissolved oxygen and selected nutrient trends in the Houston Ship Channels (Texas Water Commission (TWC) segments 1007, 1006 and 1005) during the period of 1969 through 1990 were evaluated...
Sedimentation Patterns of a Restored Tidal Wetland
Coyote Slough Lagoon was flooded as part of a local mitigation project in 1986. The design of the restored marsh included peninsulas to break up the local fetch and resulted in the development...
The Dredging Research Program of the US Army Corps of Engineers
The Corps of Engineers Dredging Research Program (DRP) was established in Fiscal Year 1988 as a seven-year program with the objective of developing products that reduce the cost of dredging...
Environmental Impacts of Small Boat Navigation: Vessel/Sediment Interactions and Management Implications
It is the intent of this review and discussions to provide state-of-the-art information on one aspect of the issue of environmental impacts associated with small boat navigation, that...
The Napeague Dunes, Long Island, NY
The Napeague Dunes of eastern Long Island, N.Y., consist of a series of three migrating parabolic dunes. The area presently occupied by this system was formerly a 2.7 Km wide inlet following...
Historical Atlas of Tidal Creeks, San Francisco Bay, California
Historic widths and depths of 69 major tidal creeks in San Francisco Bay were studied from maps dated from 1852 to the 1980's. Survey maps by the U.S. Coast Survey (and successors, U.S....
Origin, Development and Stratigraphy of Tidal Deltas at Hurricane Pass, Pinellas County, Florida?An Example of Modern Tidal Delta Architecture from a Microtidal Coast
Sequential analysis of aerial photographs taken between 1926 and 1990 have helped to define the morphological development of the tidal deltas at Hurricane Pass, and along with other historical...
Physical Modeling of Barbers Point Harbor
Physical modeling is a practical tool in the design of coastal projects. A physical model of Barbers Point Harbor located on the island of Oahu, Hawaii was constructed so that different...
Challenges Associated with Metriciation of the Nautical Chart
Under the Metric conversion Act of 1975, Omnibus Trade and Competitiveness Act of 1988, and Executive Order 12770 of 1991 all federal agencies are required to convert to the international...
Defining the Safe Navigable Depth of the Calcasieu River Ship Channel, Louisiana
Field research conducted in the Calcasieu River Ship Channel in Louisiana is described and some results of correlations between the echo sounder records and density measurements are presented....
Long-Term Shoreline Change of the Chandeleur Islands Barrier System, Louisiana: 1855 to 1989
The Chandeleur Islands are the largest barrier island system along the Mississippi River delta plain, and are characterized by low-profile, washover-dominated barriers that are rapidly...
Tidal Inlet Closure Effects on Three Mexican Coastal Lagoons
Coastal lagoons frequently evolve toward total isolation behind sediment barriers. We studied the effects of natural tidal inlet closures on three Mexican coastal lagoons with different...
Morphology of the Wadden Sea Natural Processes and Human Interference
The Wadden Sea can be subdivided in three morphodynamic units: the tidal flats, the inlets and the barrier islands. The deeply incised tidal inlets are the most active of these units;...
Coastal and Sand Spit Evolution from 1958 to 1992: Saloum River Mouth (Senegal, West Africa)
From the bathymetric map made in 1958 with the Marine Hydrographical Service in France (Number 6147), the 1976 Landsat imagery, the 1981 SPOT simulations, the 1991 SPOT data and the field...
Coastal Planning in British Columbia: Problems and Solutions
British Columbia is the most western Canadian province encompassing 27,000 km of deeply incised coastline and myriad islands and waterways. The mix of varied and often conflicting uses...
Research on the Buffer Effect of Canals
In Japan, canals for transport have been developed on the coast of urban areas. Recently, it has become evident that those areas are under chaotic conditions due to the decline of the...
Change of Estuarine Processes Due to Sea Level Rise and Navigation Channel Improvement
To investigate the relationship between the improvement of navigation channels and the change of estuarine environment under various sea level rise scenarios, numerical study was performed...
Travel Time in Mountain Basins
An empirical relationship is developed for estimating travel time in high gradient stream channels with natural beds of large gravel, cobbles and random boulders and which are flowing...
RCHARC: A New Method for Physical Habitat Analysis
The Riverine Community Habitat Assessment and Restoration Concept (RCHARC) is applied to the Gavin's Point tailwater of the mainstem Missouri River as part of studies by the U.S. Army...
