Water Quality Implications of Encapsulated Atrazine
This paper presents the movement of both encapsulated and wettable powder atrazine under no-till and conventional-till corn in the Coastal Plain physiographic region of Maryland. Soil...

Case Studies of Semi-Closed Pipeline Systems for Flexible Deliveries
The semi-closed pipeline system using the best aspects of the open and the closed pipeline systems, has many applications. It is the best adapted system for use with the variable flow...

Applications of Remote Sensing to Hydrology
This paper pulls together examples of current applications of remote sensing information to hydrology. Topics covered include rainfall, snow hydrology, soil moisture, evapotranspiration,...

ET from Shallow Groundwater Maintained by Controlled-Drainage/Subirrigation System
Soil-water management by maintaining a shallow groundwater level (watertable) via a dual purpose subdrainage-subirrigation system, is becoming popular in humid regions of the United States...

A Monumental Task
The geotechnical consultants, structural engineer and contractor combined to overcome difficult soils, underground subway structures and buried utilities when building the foundations...

Analysis of a Wharf for a Container Terminal
A balanced combination of sophisticated computer programs was employed to model the soil strata, foundation and structure of a wharf for a new container terminal in the Port of Topolobampo,...

Soil Contamination Issues at Port Marine Terminals
A preliminary survey of hydrocarbon contaminated soil and groundwater problems in U.S. west coast ports indicates that the problem occurs in most major port areas. Using the Port of Los...

Clean-Up of Contaminated Soils: A Necessary First Step in Industrial Land Redevelopment
This is a paper describing efforts by The Toronto Harbour Commissioners to demonstrate how several technologies can be effectively integrated to remove or reduce contaminant levels in...

Batter Piles and the Seismic Performance of Pile-Supported Wharves
This paper discusses the role of batter piles in the seismic performance of wharves, based on the results of a nonlinear soil-structure interaction analysis of a pile-supported wharf with...

Pile Driving: Can it Cause Slope Movement?
The potential for slope movement from pile driving is examined in this paper. Published information is reviewed to identify the primary causes of movement, which are 1) displacement of...

Measured Fill Performance at Berths 212-215 in the Port of Los Angeles
This paper summarizes the performance of an instrumentation fill constructed in open water in the Port of Los Angeles (Port). A new container-handling facility was constructed that consisted...

Non-Intrusive Rayleigh Wave Measurement System for Soil Profiling in Ports
Accurate shear wave velocity profiles have been long recognized as essential data to evaluate the dynamic response of soil deposits and soil-structure interaction under earthquake and...

Earthquake Damage Repair and Retrofit of the Seventh St. Terminal Port of Oakland
The October 17, 1989 earthquake resulted in the collapse of the two-level Cypress St. Freeway in Oakland. Television and newspaper coverage revealed the tragic loss of life and property...

Dredging Contaminated Sediments: A Monitoring Plan for Boston Harbor
Dredging and blasting will be conducted in Boston's Inner Harbor over approximately a one-year period during construction of the Third Harbor Tunnel. The silty organic surface sediments...

Analysis of Dredged Material Deposition Patterns
Between November 1, 1989 and 30 March, 1990, nearly 1 million cubic yards of dredged material were disposed in Puget Sound as the first phase (Element I) of the construction of the Navy's...

Multiuser Sites for Contaminated Sediment Disposal
The Washington Department of Ecology (WDOE) recently adopted a program to identify, rank, and clean up contaminated sediment sites in Puget Sound. Site cleanup, in conjunction with dredging...

Modeling Variable Width Buffer Zones with a Geographic Information System
It is possible to gain significant protection of water resources from nonpoint pollution with buffer strips, but frequently a single width strip is not appropriate. Geographic information...

Engineering Aspects of Wetland Design
Successful wetland enhancement, restoration, or creation projects require integration of desired wetland functions, local hydrologic and soil conditions, and biological requirements into...

Fingerprint Identification of Groundwater Petroleum Contamination Using Synchronous Scanning Fluorescence
Synchronous scanning fluorescence spectroscopy, SSF, is a simple, cost effective method for the fingerprint analysis of many petroleum contaminates in groundwater and soil samples. The...

Delaware Estuary Nonpoint Source Control Program
Preparation of the Delaware Estuary Management Plan, sponsored by the EPA and the three states of New Jersey, Pennsylvania and Delaware, is part of the national estuaries program. As part...
