The Bureau of Reclamation manages more than 8 million acres of land in the 17 Western States and is required to periodically report on the status of the lands under its jurisdiction. A...
Crop Classification and Area Estimation Using Airborne Multispectral Video/Radiometer Remote Sensing
The U.S. Agricultural Stabilization and Conservation Service (ASCS) in Logan, Utah, combines color slide 35 mm aerial photography with color video imagery to perform routine (yearly) crop...
A Markov Chain Approach for Analyzing Palmer Drought Index
Drought is conceived as a period of below normal precipitation or moisture deficiency that would affect the social and economic activities of a region. The Palmer Drought Index (PDI) is...
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...
Progress Report ARS/SCS Runoff Curve Number Work Group
The Soil Conservation Service (SCS) Runoff Curve Number (RCN) procedure works well as a single event model to estimate design storm runoff volumes from a small agricultural watershed....
Variations in Curve Number for a Reclaimed AML Site
Runoff and erosion from an abandoned mine land site near Sheridan, Wyoming were monitored for four years following reclamation. Small plots, which included lengths from 12 to 24 meters...
Gradual Development of Bores in Canal Systems
Modern computer programs for modeling unsteady flow in open channels are typically constructed using a momentum conserving form of the Saint Venant equations. This allows computation of...
Introduction to Remote Sensing for Irrigation and Drainage
Remote sensing is a rapidly emerging technology that has many potential applications to irrigation, drainage and hydrologic engineering. This paper, the first of four, introduces the reader...
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...
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...
Cranes, Concrete, Construction...and Computers
Computers are already firmly entrenched in the design process. Now, they're touching all corners of construction. Applications range from traditional project management tasks...
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...
CAD and the Corps
CAD has been a near standard feature of engineering design for the last decade, but the U.S. Army Corps of Engineers has found that the way their installations have gone about designing...
The Use of Sophisticated Three-Dimensional Numerical Models in Weather Modification Efforts
Understanding of the complex interactions between the mesoscale and cloud environment and between microphysical and dynamical processes within clouds can be substantially increased with...
