Prediction of Deformations Due to Heat Curving
This paper summarizes the state of the art in the thermal deformation techniques. Alternate analytical methods are described. The limitations and accuracy of these models are noted, and...

Structural Systems for Multispan Cable Suspended Bridges
Multispan cable suspended bridges, i. e. , cable-stayed or suspension bridges with a large number of consecutive main spans of equal size, must be carefully designed to become economical...

Development of a Double Tee Structural System for Highway Bridges
The fully precast, prestressed double tee beams are tied together by transverse post-tensioning through simple grout filled V-joints. The system provides for complete transversal continuity...

Evaluation and Surveillance of Concrete Bridge Structures
A number of cost-effective techniques are available for evaluation and surveillance of concrete bridge structures. The methods covered in this paper include: long-term bridge instrumentation,...

Furrow Modeling with Variable Hydraulic Characteristics
A zero inertia furrow irrigation model was developed to run on an IBM-compatible micro-computer. The depth gradient term of the momentum equation is approximated by averaging over the...

A Water Quality Model for Urbanized Drainage Basins
The Virginia Stormwater (VAST) Model has been developed for use on IBM compatible microcomputers to simulate stormwater runoff and nonpoint source pollution. Hydrologic and nonpoint source...

Water Supply Demand Forecast
In this study, estimates of location, quantity and timing of water demands have been investigated for determination of the adequacy of an existing water supply system, the need for additional...

ENDOW, An Expert System for Screening Environmental Features for Stream Alternations
This paper discusses development of an expert system for Environmental Design of Waterways Projects (ENDOW) by stream alteration specialists who were novices in artificial intelligence....

Expert System for Mixing Zone Analysis of Toxic and Conventional Discharges
The Cornell Mixing Zone Expert System (CORMIX) is a series of software subsystems for the analysis, prediction and design of aqueous toxic or conventional pollutant discharges into watercourses...

Interagency Standards for Automated Local Flood Warning Systems
The need exists for establishing guidelines and standards for aspects of local flood warning systems. The demand for increased flood warning systems is expected to increase due to the...

Feasibility Studies of Flood Warning-Response Plans
Local flood warning-emergency preparedness plans consist of hardware, technical activities, and formal and informal inter- and intra-organizational arrangements and commitments to performance...

Optimal Flood Warning and Preparedness Plans
This paper includes a framework for selecting the optimal investment in warning and preparedness activity. The primary factors which might influence the magnitude of cost and damage are...

On the Choice Between Annual Flood Series and Peaks Over Threshold Series in Flood Frequency Analysis
Statistical techniques are often used to estimate extreme flood events for the design of a flood-control structure or for any other flood-related purpose. Two kinds of models are commonly...

A Versatile Methodology for Flood Frequency Analysis
Many observed annual flood series exhibit reverse curvatures when plotted on lognormal probability paper. The occurrence of these curvatures may be attributed to storm and basin factors....

Confidence Intervals for Flood Control Design
The line drawn and labeled as the flood frequency curve is seldom identified as to what confidence is associated to the plot. For example while flood control designs are typically based...

Emerson, Iowa Flood Warning System
A flood warning system was installed in 1985 by the Corps of Engineers at Emerson, Iowa as part of Emerson, Iowa Flood Control Project on Indian Creek. The warning system consists of two...

The Santa Ana River Flood Forecasting System
A real-time flood forecasting and reservoir operations simulation system has been developed for the Santa Ana River Basin, located in southern California. The system consists of generalized...

Denver Area Real Time System
This paper presents a discussion of the development of the Denver Area Real Time System which will be used to regulate the Denver reservoir system on a real-time basis. Its main components...

Effect of Length of Precipitation Record on Recharge Estimates
The effect of the length of precipitation record on groundwater recharge estimates is examined using data from eleven precipitation gages located on the Nevada Test Site. It is concluded...

Well Field Management Designed to Miminize Impact on Surface-Water Flow
Restrictions placed on the operation of a well field used for public water supply initiated an investigation to develop management techniques that would maximize utilization of the well...
