Microcomputer Applications in Flood Management
Historically Salt Lake City has been subject to flooding from spring snow melt runoffs. Even though the volume and the rate of runoffs were similar during both years, the 1984 runoff created...

Unique Considerations in the Detroit DPM Foundation Design
Foundation design for the guideway of Detroit's Downtown People Mover (DPM) was influenced by a variety of unique considerations. Severe loading conditions were created by...

Computer Keeps New Orleans: Head Above Water
The city of New Orleans has been beset with drainage problems since its founding in 1718. A major drainage system was installed in the city in the late 1800s, but it has grown increasingly...

Drainage Tunnels Save Freeway Link
A 15 mile section through downtown Phoenix will complete Interstate 10. After years of delay, the project is now close to completion. The project required construction of 6.5 miles of...

Development and Management Aspects of Irrigation and Drainage Systems
The 1985 Irrigation and Drainage Division Specialty Conference held in San Antonio, Texas on July 17-19, 1985 covered major topics on watershed management and water conveyance, drainage...

Drain Maintenance in the Imperial Valley
Imperial Valley, located in the southeast corner of California is one of the most intensely irrigated areas in the world. Since Colorado River salinity is currently about 800 mg/l (1....

You Need More Than a Plumber's Helper
Maintenance of subsurface drains may be the least understood and most neglected of all maintenance activities carried out by irrigation districts. Few irrigation districts have a maintenance...

Physical Evaluation of a Buried Drainage System
The drainage problem in the 600,000 acre (1. 5 million ha) Westlands Water District (District), located in the Central San Joaquin Valley in California is that of a perched saline groundwater...

Microcomputers in Urban Drainage Design
Microcomputers offer an inexpensive method for increasing the efficiency and effectiveness of drainage design personnel. This paper discusses some of the benefits and uses of microcomputers...

Assessment of Drainage Infrastructure for Urban Areas
Public concern about the adequacy of the urban drainage system rises and falls with the rainfall patterns. Because the 'problem' depends on many variables, including...

Data Base in Your City's Future?
The city of Bellevue, Wash. computerized its public works maps in 1979 because Bellevue was using the county's maps, and their updating wasn't keeping up with suburban growth. Now this...

Geotechnical Innovations: Why Seldom Used in Highways?
Ground improvement methods introduced within the past decade to American geotechnical engineers offer cost savings, ease of construction and reduced construction time. Amont these innovations...

Application of Methods of Probabilistic Characterization of Soil Properties
The use of probabilistic methods to describe soil properties has many applications. One such application that has been developed is in the area of probabilistic slope stability analysis....

In-Plane Composite Drains
Drainage of water from outside basement walls, behind retaining walls, or highway cut or fill slopes, has long been a problem. A common solution is the aggregate drain. Often, installation...

Dredged Slurry Stabilization for Seagirt Marine Terminal
The Seagirt Marine Terminal is constructed on reclaimed land on dredged spoil from the I-95 Fort McHenry Tunnel in Baltimore, Maryland. Three stabilization procedures considered applicable...

Grouting Rehabs Earth Dam
To accommodate increased storage needs the Pennsylvania Power & Light Company had to reactivate a fly ash basin and raise an adjacent embankment dam. However, seepage through the...

Steady-Site Dispersion of Pollutants in Rivers Near Sewage or Drainage Outfalls
A theoretical model is developed for determination of concentration distribution of pollutants in a river. Pollution is caused by the disposal followed by dispersion of sewage or drainage...

Predicting Ground-Water Drainage to Surface Mines
A two-dimensional, finite-difference numerical model is used to simulate the drainage of ground water into a surface coal mine. Graphs of dimensionless head as a function of dimensionless...

Hydraulics and Hydrology of Border Irrigation
Proper description of the hydraulics of irrigation of farmland is necessary in management. Many descriptions of furrow or border irrigation are not adequate to describe truly physically...

Decreases in Runoff and Sediment Yield by Drainage
Runoff and sediment yield from three small agricultural watersheds were measured during four winter rainfall seasons. Following two rainfall seasons of data collection, a subsurface drainage...
