Field Instrumentation Program Vital to Deep Excavation Project
An extensive field instrumentation, monitoring and evaluation program was implemented for a seven-level deep excavation project in Boston. Using the observational approach, the information...
Pressuremeter Stress Relaxation Testing in a Permafrost Tunnel
In the spring of 1988, a geotechnical testing program was carried out in the U.S. Army CRREL Permafrost Tunnel, located at Fox, near Fairbanks, Alaska. In all, some thirty cone penetrometer...
Use of a Tie-Back Retaining Wall to Stabilize a Moving Landslide
After failure of a gravity retaining wall, a moving landslide was stopped and stabilized by a tie-back retaining wall. The design considered the active landslide and residual strength...
Remote Sensing and the Coastal Management in Brazil
This paper intends to demonstrate the possibility of employing remote sensing techniques in the Brazilian Coastal Management Program (Programa Brasileiro de Gerenciamento Costeiro). It...
Aerial Videotape Mapping of Coastal Geomorphic Changes
An aerial geomorphic mapping system was developed to examine the spatial and temporal variability in the coastal geomorphology of Louisiana. Between 1984 and 1990 eleven sequential annual...
Sonar Mapping of Giant Kelp Density and Distribution
The methods of estimating the density and distribution of giant kelp, Macrocystic pyrifera, and substrate type, using side-scanning and down-looking sonar are described. These techniques...
Environmental Monitoring Systems?A Case Story?The Great Belt
The law passed by the Danish Parliament on the construction of a combined bridge and tunnel across the 18 km wide Great Belt, included an environmental design criteria. This has initiated...
Marine Minerals Investigation in the Mid-Pacific Area; An Example of State and Federal Government Cooperation
For the past six years, representatives of the Federal government and the State of Hawaii have joined together to investigate marine cobalt-rich manganese crust occurrences in the U. S....
Geological Assessment of Offshore Sand Deposits
The United States Atlantic and Gulf of Mexico continental shelf contains large numbers of surficial sand deposits. The search for sand resources for metropolitan construction and coastal...
A Reef Conservation Project Involving Sport Divers in Singapore
The limited extent of Singapore's territorial waters places almost all the area within the boundary of its harbours. This includes many of the fringing and patch reefs associated...
Studies on Meiofauna on Rio de Janeiro Coast, Brazil
This work presents a preliminary survey of the meiofauna groups and the distribution, abundance and temporal changes of the community at Praia Vermelha (Rio de Janeiro, Brazil), in July...
Recession of the Littoral Zone Cliffs of the Bristol Channel, U.K.
A recent investigation of the mass movement modified cliffs along the Bristol Channel coastline has been achieved by utilising ground survey data, historical and contemporary cartographic...
The British Beach and Nearshore Dynamics (B-Band) Programme
A large scale collaborative field based research programme (B-BAND), aimed at measuring the small scale processes associated with nearshore dynamics on macro-tidal beaches, is currently...
Bedload Transport Measurement by Imaging of Tracers
A dyed-sand tracer technique is developed for investigation of bedload under laboratory oscillatory flows. Imaging of the tracer with high speed photography allows the creation of time...
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...
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....
Monitoring of a Nearshore Disposal Mound at Silver Strand State Park
The migration of an underwater disposal berm constructed in December 1988 approximately six miles south of the entrance to San Diego Bay is investigated. The berm was composed of medium...
Integrated Photogrammetric and Geophysical Monitoring of Shoreline Instability in Littoral Cells in the Pacific Northwest, USA
Several factors have recently focused on the attention of government agencies, academic researchers, and the general public on coastal erosion and beach resource management in the Pacific...
Topographic Responses to the Construction of Large Port Structures on Oarai Coast
Large offshore breakwater and groins have been constructed at Oarai Port, Japan. As a result, the coast experienced significant topographic changes. In this paper, the responses of the...
