Electronic Gymnastics
Efforts are being made to have all the parties to a project share the same, current information. In order to do so, civil engineering firms are jumping through electronic hoops to get...

Optimization: An Emerging Technology
The technology of formal, numerical structural optimization is neither mysterious nor complex. Software programs are now available for use by engineers who do not have detailed knowledge...

Computers: What Do Students Need to Know?
This article is based on interviews with three professors at three universities, a recent graduate from each school, and the graduate's employer. The interviews show that...

Automating Bridge Design
To avoid some of the pitfalls of manual design calculations, Parsons Brinckerhoff Quade & Douglas engineers designing a series of bridges for a $280 million section of the New...

Expert Systems for Risk Analysis
An explanation is presented on why construction risk analysis can be handled by an expert system computer program. The author offers a prototype construction risk management expert system...

Building Frame Analysis in Basic
Moment distribution has, for the past 30 years, been the most popular method of analysis for statically indeterminate structures. Programmed in Basic for the microcomputer with relative...

Design of Large Steam Turbine-Generator Foundations
This report is a guide for engineers who are responsible for the design and analysis of large turbine-generator foundations. A description of the various components of turbine-generator...

Coastal Sediments
The two-volume Proceedings of Coastal Sediments '87 contain more than 150 full papers delivered at a specialty technical conference of the American Society of Civil Engineers...

Overview of Canal Control Concepts
An overview of terminology and philosophies of canal control, plus brief descriptions of canal automation technologies, is given. The justification given for examining control schemes...

Overview of Financial and Economic Considerations
The financial and economic analyses of plans to rehabilitate and automate irrigation water delivery systems are complex technical exercises that require the expertise of professional economists...

Economic Analysis of Irrigation Rehabilitation Projects
This paper discusses the assessment of the costs and benefits of irrigation rehabilitation and modernization projects. It summarizes the methodology used at the World Bank to assess the...

Penetrative Convection in Mixed Layer Models
While surface heat transfer is important in lakes and reservoirs, solar radiation, which penetrates the water surface and is absorbed in the water column, also exists. In this work, a...

The NOS Experience in Real-Time Measurements of Tidal Currents
NOAA'S National Ocean Service (NOS) uses the term RADS, Remote Acoustic Doppler Sensing, for a new class of oceanographic instruments that uses acoustic backscatter to probe...

Parking Lot Drainage Design: Gainesville, Florida
The construction of a 10-acre (4. 05 ha) parking facility (1,000-car capacity) at the University of Florida during 1984 presented the potential for increasing downstream flooding and for...

Nonhomogeneous Terms in the Unsteady Flow Equations: Modeling Aspects
A study is in progress to identify the relative significance, effects, and benefits attributable to the use of one-dimensional, unsteady, open-channel, flow-simulation models employing...

Preliminary Engineering Design of an Artificial Tidal Lagoon System in Kuwait
A coastal resort project was planned for a 30 hectare site along the Arabian Gulf approximately 69 km south of Kuwait City at Dubaiyeh. The master plan, originally developed by Kuwait...

Applications of the Singular Point Method to Hydraulic Analysis of Spillways
A computer-oriented procedure is described to develop rating tables for side channel spillways. The procedure includes three sets of computations which have to be performed iteratively...

Computation of Supercritical Flow in Open Channels
The use of two explicit, shock-capturing, finite-difference schemes, Lax and MacCormack, for the solution of two-dimensional shallow-water equations in steady, supercritical flow is investigated....

Lower Mississippi River Salt Intrusion Modeling
A laterally averaged numerical model called LAEM has been employed for both a 40- and 55-ft channel. In addition, LAEM has been applied with an increased height of the natural river crossing...

Nontidal Exchange Processes at the Chesapeake Bay Entrance
Magnitudes of gravitational and meteorologically-driven exchange at the entrance to the Chesapeake Bay are compared using current measurements, numerical model runs and subtidal volume...
