Stochastic Simulation and Optimization of Irrigation Canal Network Flows
This paper investigates the effects of parametric and objective uncertainty on simulation and optimal hydraulic design of irrigation canal networks. A model of spatially-varied flow in...

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...

Linking GIS with Hydrologic Modeling
A GIS-based methodology for conducting rapid assessments of pesticide and nutrient transport within agricultural watersheds was recently developed. This methodology is based upon the use...

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...

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...

United States Metrication and the EC 92
Major Congressional legislation adopted in 1988 was related to USA trade and competitiveness problems of the Nation. The legislation contained a section on metrication that required all...

Metrication of Construction?A Message to the American Society of Civil Engineers
The author discusses the reasons for metrication of the U.S. construction industry, describes the Canadian experience in this area, and outlines the necessary steps to alleviate the metrication...

Metrication Between Canada and the USA?A Staged Adoption
Great Britain has led the way for change from English to metric units. There, as in the United States, industry and trade were the motivating forces for change. The gradual change to metric...

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...

Expert Systems for Civil Engineers

This committee report, Expert Systems for Civil Engineers: Knowledge Representation, focuses on how engineers represent knowledge in expert...

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,...

Water's New World
Potential applications of computer automation in the water industry have become increasingly apparent in the last several years. A growing number of water agencies are considering purchasing...

Highway Design in 3-D
Limitations in the flexibility and intelligence of commercial roadway design packages led Hart-Freeland-Roberts, Inc., Brentwood, TN, to write its own highway design software. From the...

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...

Appropriate Technology for Flood Warnings
Computers can help protect cities and other developed areas by enhancing flood warning systems, but smaller communities may not be able to take advantage of their sophistication. The Corps...

Expert Systems: Ready to Hit the Road?
Expert systems, programs that take the rules a person uses to solve a problem and encodes them into a computer, are starting to get serious examination from DOTs around the country. The...

Water Management Under Drought Conditions an Overview of Practices by Federal Agencies
The management of water resources under drought conditions is a diverse topic which has received added emphasis recently as a result of prolonged droughts in parts of the United States....
