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...
AVL's Future Holds Little Value without Integrated Data Communications for Total Mobile Resource Management
The future of automatic vehicle location (AVL) lies in broadening its definition for greater market acceptance and applicability. AVL by itself is for limited utility. To solve real-world...
Comparative Accuracies of Technologies for Vehicle Location and Navigation
A variety of vehicle location and tracking technologies are under consideration for such IVHS applications as Automatic Vehicle Location (AVL), Computer Aided Dispatch (CAD), and vehicle...
Digital Mapping for Road Navigation in Japan
In Japan, more than 300,000 vehicles are presently equipped with car navigation systems. Development of these systems had been greatly aided by the completion of a standardized digital...
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...
Minimum Streamflow for Habitat?A Case Study. Menikganga River Diversion Project?Sri Lanka
Determination of minimum streamflows to be left in the stream channel for the sustenance of the downstream habitats becomes a difficult task when quantitative requirements of such habitats...
Dam-Break Study for Large Floodplain Area - A Case Study
In simulating a dam break flood in a large floodplain, the maximum flood level is sensitive to the off-channel storage volume used in the channel routing. An incorrect estimate of the...
Sediment Entrapment by Stream Channel Vegetation
Degraded headwater streams are common in the mountainous West. They have experienced a variety of stresses from public and private uses and will require specific management consideration...
Stable Slopes of Alluvial Channels
An alluvial channel responds to the variation in the incoming sediment by changing its cross-section and especially the slope. Regime relations formulated by Lacey (1930) and many subsequent...
Effect of Choptank Watershed Drainage Project on Stream Temperatures
Between 1974 and 1982, the Soil Conservation Service, U.S.D.A conducted a stream study on the Choptank Watershed in Caroline County, Maryland to monitor the effects of channel construction...
Engineering Geomorphology
Engineering geomorphology is the application of geologic and geomorphic principles to the solution of river engineering problems. Development of a process-based understanding of a problem...
Screening of Bridges in New Jersey for Scour
New Jersey Department of Transportation has embarked on a program to evaluate all existing bridges over waterways to assess their vulnerability to failure by scour. The Stage I (Screening...
