Predicting Water Quality as Affected by ET Using the Root Zone Water Quality Model
The Root Zone Water Quality Model (RZWQM) is a physically based simulation model used to predict water and solute movement running from, moving through, and leaching out of the root zone....
Simulated Citrus Water Use from Shallow Groundwater
Citrus groves in south Florida are planted on poorly-drained soils that support a shallow water table which can contribute some or all of the citrus evapotranspiration (ET) requirement...
2-D Evaporation and Root Extraction in an FEM
Two-dimensional processes of soil evaporation and moisture extraction by plant roots (horizontal and vertical) were incorporated into a saturated/unsaturated finite element model (UNSAT2)...
Simulating the Effects of Deficit Irrigation for Furrow Systems
The distribution of irrigation water across a field can dramatically affects management of furrow irrigation systems as water supplies become limiting. To assess management strategies...
Soil Moisture and Runoff?Another Look
Infiltrometer studies conducted on numerous soil types in various locations of the United States which had soil moisture data were used to calculate the runoff Curve Number (CN) of both...
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...
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...
