Thoughts on a Different Approach to Seismic Design Codes
The aim of this paper is to show that some of the principles on which conventional structural design is based are not directly applicable to seismic design. Seismic design, and the corresponding...
Courting Public Opinion
Promoting good community relations is an integral part of hazardous waste projects. Before field investigations are conducted, neighboring communities should be advised of the proposed...
Pressure Injected Footings in Piedmont Profiles
Comparatively little has been published on the behavior of pressure injected footings in the Piedmont residual soils and weathered rocks. It is the purpose of this paper to describe some...
Biological Treatment of Trichloroethylene
Trichloroethylene and related compounds such as cis- and trans-1,2-dichloroethylene and vinyl chloride are common contaminants of ground water in industrial areas. In oxygenated ground...
Maintaining the Gateway to the Columbia Basin?A Plan for Improvement
Portland District has begun a Maintenance Improvement Program to recommend procedures to reduce annual operations and maintenance costs while providing safe and efficient ship passage...
A Wetland Habitat Assessment Method using Birds
A wetland habitat assessment technique (HAT) using birds as indicators of habitat quality was developed from the method of V. R. Holmes et al. , (1986) and J. W. Graber and R. R. Graber...
Concrete Armor Mats: Large-Scale Wave Tank Tests Wave Stability Tests
Concrete mats provide an alternative to the more conventional shoreline stabilization techniques. Material requirements are low, placement techniques are straightforward and they tend...
Coastal Groundwater Outflow: Solution to a Dynamic Problem
The pattern of fresh groundwater outflow at the coastal margin of a phreatic aquifer can be approximated by a quasi-transient analytical model. The suggested procedure includes transformation...
Techniques for Field Survey of the Eastern Red Sea
A system for generating a large scale resource inventory using a framework of geographically discrete site assessment quadrats has been used for a survey of the Eastern Red Sea. The quadrat...
REMOTS?: Reconnaissance of Benthic Environments
REMOTS(REGISTERED TRADEMARK) technology, a combination of sediment-profile photography and computer image analysis, was developed to address shortcomings in traditional benthic sampling...
Evaluating LNG As a Fuel for Diesel Shrimp Boats
Liquefied Natural Gas (LNG) is being evaluated as a viable fuel for diesel engines. A shrimp boat is being used to evaluate the LNG system. LNG has an economic advantage to diesel fuel;...
Strengthening Old Floors
The floors of the historic City Hall and Courthouse in Minneapolis had withstood 80 years of hard use before they have to be analyzed and brought up to code. The building is about 300...
Effects of Semi-Impoundment on Fish and Crustacean Nursery Use: Evaluation of a Solution
Semi-impoundment of the marsh is one of the primary 'solutions' currently recommended to combat coastal marsh erosion, and also to improve habitat for waterfowl,...
Use of Fish Liver Pathology as a Tool for Environmental Assessment (`siabstract)
Despite the recognized value of fish liver pathology as an environmental assessment tool, little guidance is available on the design and interpretation of such studies. Proper study design...
Geomorphology, Convergent Margins and Earthquakes
Underthrusting along convergent plate margins, is commonly accompanied by the occurrence of shallow focus, large magnitude thrust earthquakes ( greater than magnitude 7. 5). In the subduction...
Evaluation of Tsunami Risk at the Southwest Coast of the Iberian Peninsula
The southwest coast of the Iberian Peninsula has a long history of being affected by tsunami waves. The tsunami risk analysis carried out for this area included the compilation of a catalog...
The ARC Reefs: Designed Artificial Reef Systems
Results of laboratory tests and preliminary results of field tests indicate materials and designs incorporated in The American Reef Corporation (ARC) designed artificial reef structures...
Modeling Dilution of Wastewater Outfalls in a Tidal Estuary
Field studies and modeling have been conducted to assess initial dilution of wastewater outfalls in Puget Sound, a fjord-like estuary in the State of Washington. Recent numerical dilution...
Simulating Nonpoint Source Runoff to Coastal Waters
The simulation of nonpoint source runoff to coastal waters is based on data requirements of land use, soil type. Evapotranspiration and runoff capacity are determined from terrestrial...
Methods for Developong a Management Plan for a Small Tidal Inlet: Mecox Inlet, Long Island, New York
Few management studies have examined small ephemeral tidal inlets. The magnitude of short-term shoreline changes associated with some ephemeral inlets makes desirable the development of...
