Criteria for Selecting a Reservoir Routing Method
Results of an investigation comparing dynamic and storage reservoir routing applied in dam safety analyses are presented. Outflow hydrographs computed by these reservoir routing methods...

Verifications and Applications of a Nonpoint Source Pollution Model
To meet the needs of the Illinois Comprehensive Monitoring and Evaluation (CM&E) project of the Rural Clean Water Program (RCWP), the Agricultural Nonpoint Source Pollution Model...

Optimization of Complex Hydrologic Models Using Random Search Methods
The primary objective of automated calibration of complex conceptual hydrologic simulation models is to find the global optimum of a specified response surface. While direct search techniques...

Automatic Calibration of Conceptual Rainfall-Runoff Models
An automatic calibration strategy applied to land and channel components of the National Weather Service River Forecast System is outlined. Aspects discussed include the objective function...

A New Method for Synthesizing a Six Hour Unit Hydrograph
A new methodology was devised that would use readily available basin physical parameters for the determination of unit graphs in undeveloped and ungaged areas. Rather than using small...

Modified CIMIS Irrigation Scheduling Program
CIMIS, California Irrigation Management Information System, is a program that collects weather data around the state to assist irrigators in planning and scheduling their irrigations....

Serviceability Limit States in Load Space
Deflection and elastic limit state curves are drawn in load space using a nonlinear structural analysis program. Use of load space simplifies computation of point estimates of serviceability...

Geologic Assessment of Seismotectonic Hazards
Design and modification of dams require evaluation of potential seismotectonic hazards based on consideration of the historic earthquake record and deterministic evaluation of geologic...

Prediction and Measurement of Wind Response: Case Story of a Wind Sensitive Building
The wind-induced horizontal accelerations of a 43 story office tower in New York City were monitored during 11 occasions over a period of about six months. The building dates back to the...

Performance of Viscoelastic Dampers in World Trade Center Towers
The viscoelastic damper was conceived and developed as a part of the structural design for the Twin Towers of the World Trade Center, New York. They are an integral and an essential part...

Polymer Concrete for Structural Applications
Polymer concrete (PC) has been used extensively in the United States primarily as a repair material for portland cement concrete. The excellent flexural and compressive strength durability...

Reliability of Structural Systems With Multiple Limit States
The purpose of this paper is to present a systematic treatment of the reliability of structural systems with multiple limit states. Several performance criteria (e. g. , excessive deflection,...

Dioxin and Resource Recovery
The 1987 ASCE Dioxin and Resource Recovery Symposium was held at the New York Hilton Hotel, New York on February 10, 1987. The conference served as an opportunity to assess the issue of...

Applications of an Integrated Traffic Analysis Package
This paper presents an integrated traffic analysis package called AAP (the Arterial Analysis Package). AAP, which was developed by the Federal Highway Administration (FHWA), contains three...

Modeling Permissive Movements in TRANSYT-7F
Traffic Network Study Tool (TRANSYT-7F) is one of the most widely used traffic flow analysis and traffic signal timing optimization models in the United States and elsewhere. Through 'Release...

Integrated Information System for Traffic Control Device Management
Traffic engineers and planners have the day-to-day responsibility to maintain the safety and operational efficiency of streets and highways in their jurisdictions. Managing traffic control...

Freeway Analysis Using A Micro Version of FREQ
FREQ8PE is a freeway corridor simulation model. It is a batch processing mainframe program written in ASCII FORTRAN IV, which performs three basic functions: simulate freeway queueing,...

A Decision Support System for Freeway Corridor Analysis
When the scope of a particular corridor study dictates the review and analysis of a relatively large number of road segments along major transportation corridors, the integration of roadway...

Conversion of the MIDAS Accident Analysis Model
The MIDAS (Michigan Dimensional Accident Surveillance) System has been developed to provide accident analysis capability. A microcomputer version of MIDAS is being developed to make the...

KSLAD: A Traffic Accident Data Analysis Program
Originally developed to run within the dBASE III (tm) operating environment, Kansas Local Accidents Database (KSLAD) has since been upgraded to operate under dBASE III Plus (tm). Work...
