Recent Developments in Hydrologic Instrumentation
The availability of space-age materials and implementation of state-of-the-art electronics is making possible the recent developments of hydrologic instrumentation. Material developments...
A Microcomputer Dispersivity Evaluation Method for Thick Aquifers
The Littoral Environment Observation (LEO) program uses volunteer observers recruited to obtain daily visual observations of such coastal variables as breaker height, wave period, direction...
Littoral Environment Observation Program
This paper presents a method for determining the longitudinal, transverse, and vertical dispersivities of a thick aquifer for a free convection tracer test using only measurements from...
Development of a Practical Method Simulating Oil Spill Migration (OSPIM) in Soils
Many ground-water modeling studies can be performed on currently available microcomputers. The greatest problem associated with the proliferation of ground-water modeling software for...
Alternative Procedures for Investigating Failures
Failures of engineered structures continue to occur. This is despite rapid advances in engineering theory, new, more sophisticated methods of analysis, and streamlined techniques for preparing...
Failure Information Needs in Civil Engineering
If we are to learn from failures of engineered facilities, failure information must be in a useful form, and it must reach those who can effect improved practice. This paper discusses,...
Ensuring Quality Construction
This paper describes the US Army Corps of Engineers' efforts at procuring quality construction: 1) a three-phase approach (preparatory, initial, follow-up) was developed to...
Can We Save the Ogallala?
The useful life of the Ogallala Aquifer, which underlies seven western states, can be extended indefinitely through water conservation in the widest sense of the term. In addition to optimization...
Hazardous Waste Cleanup: The Preliminaries
Court-ordered negotiations rather than a trial took five years but led to a flexible plan for cleaning up an inactive hazardous waste disposal site in Niagara Falls, N.Y. Contamination...
Hydropower's Newest Generation
Higher energy prices and strong incentives from the federal government have caused hydropower developers to consider sites that just a few years ago were scoffed at as mere trickles. Intense...
Two Projects Became One
Nontraditional funding and a new law were required before two Cortez, Colo. projects could be combined. Building a new canal and enlarging and lining an existing one to move water in essentially...
Small Water Users�Planning Crisis
Planning to rehabilitate small water systems�both irrigation and municipal water supply�often is ignored. In contrast, planning for new construction and for operations/maintenance work...
Avoiding Disputes: The Construction Manager's View
Avoiding and minimizing contract disputes, from the construction manager's (CM) point of view, begins during the preliminary planning and design stages and continues throughout...
Construction Inspection?The Last Line of Defense
Construction inspection, or a quality assurance program, is typically the last line of defense in relation to claims for the constructed project. The quality assurance team should be a...
Tension-Compression Test of a Concrete Specimen Via a Structure Damage Theory
The concrete sample is assumed to consist of a large number of aggregates and cement paste. Their material properties are assumed to be perfectly elastic. The effective elastic property...
Solutions in the Pipeline
Water and sewer agencies across the country are beginning to feel more comfortable about pipeline rehabilitation. Where once replacement was the ony alternative considered for aged, clogged...
Private Funds, Public Projects
Tapping private sources for public services is not new, though the concept has advanced from traditional contracting for services, which has been around since pre-Revolutionary War days....
New Safety for Old Dams
Shortly after the Phase I inspection program conducted by the U.S. Army Corps of Engineers in 1978-81, the Pennsylvania legislature authorized $300 million for repair of dams, ports and...
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...
Computer Applications in Water Resources
The use of computers in all engineering disciplines has, in the past decade, increased to the point where virtually all engineers now use these powerful tools. This is especially true...
