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...

Retention Parameter Estimates for Curve Number Runoff Procedure
A technique is developed for computing estimates and associated probabilities of the retention parameter S in the Soil Conservation Service curve number runoff procedure. This technique...

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...

Calculation of Runoff from Rainfall Using NURP Data
Peak runoff flows and flood hydrographs are important elements in the design of drainage and flood-protection structures. The validity of methods for predicting peak flow from rainfall...

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...

Design of Latticed Steel Transmission Structures
This standard, Design of Latticed Steel Transmission Structures (ASCE 10-90), provides requirements for the design of guyed and self-supporting...

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...

Taming Tornado Alley
Some structures�such as nuclear power plants�need complete protection from tornadoes regardless of the high costs of design and construction. Public facilities need protection too, but...

New Cruise Terminal for San Francisco
A new international Cruise Terminal is being developed at Pier 30-32 in San Francisco, to replace present inadequate facilities at Pier 35. The Cruise Terminal will be developed as part...

On-Off Terminal Ship-to-Rail Transfer
The intermodal situation of U.S. ports is still evolving, and port planners will be facing difficult decisions regarding IM Configurations. This article was intended to assist 'perplexed'...

Port of Portland's Berth 601 Floating Dock
The Port of Portland's facilities, being located on the Columbia and Willamette Rivers, are subjected to extreme water level fluctuations. Over the years, the Port has used floating docks...

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,...

Deep Water Container Wharf & Crane Foundation
A deep water anchored steel bulkhead and a parallel-independent low-profile, pile supported crane rail foundation with special stowage areas are discussed from soils investigation, through...

Case Study ? Elliott Bay Marina Floating Moorage
The recently completed Elliott Bay Marina project in Seattle is one of the larger projects of this type in the country, with 1196 slips ranging from 32 feet to 60 feet, a floating fuel...

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...
