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...

Darcy-Weisbach Roughness Coefficients for Selected Residue Materials
A laboratory study is conducted to measure Darcy-Weisbach roughness coefficients for corn, cotton, peanut, pine needles, sorghum, soybeans, sunflower, and wheat residue. Varying rates...

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...

Engineering Answers to Groundwater Impact Questions Using a Geographic Information System (GIS)
Environmental concerns have raised complex questions about the impacts of increased groundwater levels adjacent to navigational pools along the Red River, Louisiana. Previous studies had...

Climate Change and Water Management Flexibility
Changes in regional climate expected to occur as a result of the accumulation of greenhouse gases may have significant impacts on water resources. In this paper, I examine the sensitivity...

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

Applications of Remote Sensing to Irrigated Agriculture
Several uses for satellite digital imagery and data from portable field radiometers have been developed for the monitoring of agricultural crops, their yields, insect and disease attacks,...

Applications of Remote Sensing to Drainage
This paper summarizes examples of current applications of remote sensing information to drainage. Topics covered include drainage basin parameters, drainage problem identification, salinity...

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...

Road and Airport Pavement Response Monitoring Systems
This proceedings, Road and Airport Pavement Response Monitoring Systems, consists of papers presented at the symposium held in West Lebanon,...

Beyond Push-Button GPS
In 1993, the U.S. Air Force Space Command will complete its deployment of 24 satellites for the Global Positioning System, affording 3-dimensional positions and velocities 24 hours a day...

A Monumental Task

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,...

Application of Traffic Engineering Concepts to Pleasure Boat Traffic
The Los Angeles County Department of Beaches and Harbors initiated a study to investigate the feasibility of adding slips along the main channel in Marina del Rey in response to the surplus...

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...

Clean-Up of Contaminated Soils: A Necessary First Step in Industrial Land Redevelopment
