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...

Effect of Wind on Coastal Construction in Florida
The State of Florida's tidal shoreline is 8,426 miles long. Both the east and the west coast of Florida is subjected to several coastal storms each year. The present study...

Ocean Mining with Shoreline Protection
This paper describes an existing construction system that permits building large concrete structures directly on the water in low-cost floating formwork with unskilled local labor operating...

A Conflict Avoidance Methodology for Port Dredging Issues
Port dredging operations have often been the focus of controversy over environmental and funding disputes. This paper asserts that adversarial relationships among interested parties will...

Crab and Salmon Habitat Enhancement in Grays Harbor Estuary, Washington
A description of mitigation for crab losses and reduced salmonid habitat, expected to occur during construction of the Grays Harbor, Washington, Navigation Improvement Project, is presented....

Coastline Management: A Challenge for Developing Countries
Coastal erosion has been a worldwide problem of primary concern to coastal management and development. To arrest the coastal erosion processes along the coastline of developing countries...

Onsite Compliance Programs for Major Oil and Gas Projects
Major oil and gas projects developed in Santa Barbara County are monitored for compliance with conditions of approval through various enforcement and compliance programs. the Resource...

Effective Mitigation of Air Emissions from OCS Sources
Unmitigated, platforms and associated facilities in the OCS typically emit large quantities of air pollution from power generation, drilling, transportation and other activities related...

Engineering Methods for Predicting Beach Profile Response
This papers contains a review of so-called 'engineering methods' for predicting beach profile change based on equilibrium profile concepts. In the first part...

Modelling of Cross-Shore Flow and Morphology
A one-dimensional, time-dependent model is presented which describes the evolution of wave groups and associated long waves over an arbitrary profile, in a short-wave averaged sense. Model...

Modelling of Cross-Shore Transport
The validity of cross-shore sediment transport modelling in terms of time-averaged velocities and concentrations has been investigated....

Simulation of Bedload Transport of Marine Gravel
Using combined current meter and acoustic measurements, detailed concurrent time series of instantaneous bedload transport rates and flow turbulence have been obtained. The duration, interval...

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...

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...

Design Guidance for Nearshore Berm Construction
Construction of nearshore berms has been gaining acceptance as a cost effective beneficial use of dredged material. This paper presents a systematic methodology for design and evaluation...

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...

Effects of Temperature and Mean Cell Residence Time on Enhanced Biological Phosphorus Removal
The effects of temperature and mean cell residence time (MCRT) on biological phosphorus and nitrogen removal were investigated by operating pilot-scale continuous-flow activated sludge...

Reliability-Based Estimates of Wetland Detention Times for Wastewater Treatment
Determination of the hydraulic residence or detention time is often the first step in design of wetlands constructed for wastewater treatment. Current methods for estimating wetland detention...

Construction Management at Sikes Superfund Site
Lockwood, Andrews & Newnam, Inc. (LAN) is providing Construction Management services on the Sikes Superfund site. The project involves constructing an incinerator on-site and incinerating...

Noise Control Program for the Boston Harbor Project
A noise control engineering program has been instituted for the Boston Harbor project to make the facility virtually inaudible at the property line. The program integrates the noise mitigation...
