Southeastern Drought of 1986 - Lessons Learned
An interim drought management plan for the Apalachicola-Chattahoochee-Flint (A-C-F) river basin was completed in April, 1985, just in time for testing as the drought developed. Objectives...

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...

Fault-Tolerant Design for Data Acquisition and Flood Forecast Systems
An innovative fault tolerant flood warning system is currently being installed in the Passaic River Basin. The new system is designed to automatically tolerate the failure of major components...

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....

Reliability of a Frictional System with Uncertainty
In recent years, more emphasis has been placed on the study of random vibration of structures with uncertain parameters. Most of these have dealt with second order statistics of the response...

Unified Approach to Reliability-Based Structural Optimization
The purpose of this paper is to present a unified approach to reliability-based structural optimization. The emphasis is placed on recent developments in the field including optimal design...

General Considerations for Seismic Stability
The basic design consideration is provision of sufficient stiffness, strength and adequate ductility for the varied loads imposed on the building. Adequate stiffness is needed to resist...

Risk Assessment for Cladding Panels: An Expert Systems Approach
Risk assessment for structures in the context of wind engineering involves many factors such as wind hazard, the wind sensitivity of the structure and the socio-economic value of the structure....

Time Domain Structural Parameters Identification
Identification techniques for linear lumped-parameters models of vibrating structures are critically assessed using data produced by numerical simulations. The structural model is excited...

Anchorage Forces for Z-Purlin Supported Standing Seam Roof Systems
This paper presents the results of a limited study to determine if the provisions of Section D. 3. 2. 1 'Anchorage Bracing for Roof Systems Under Load with Top Flange Connected...

Modeling Errors in Fatigue Crack Growth Laws
Using the fracture mechanics approach to fatigue it is possible to update estimates of a structure's reliability against fatigue failure given new information on the state...

Application of a Hybrid Strategy for Structural System Reliability Analysis
The authors have attempted to explain a strategy for structural systems reliability calculations. In essence, it involves the use of different methods at appropriate times in the search...

Reinforced Concrete Column Reliability
A method is proposed whereby the reliability is obtained using the stable configuration approach of structural system reliability. The configurations are defined based on imposed strains...

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,...

Environmental Engineering
The American Society of Civil Engineers annually sponsors a Specialty Conference on Environmental Engineering. The 1987 Conference was held in Orlando, Florida on July 7-9, 1987 with cooperation...

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...

An Adaptive Control Strategy for Signalized Intersections
This paper presents a microprocessor-based computational strategy for real-time demand-responsive traffic signal control. The strategy, termed OPAC (Optimization Policy for Adaptive Control),...

Intelligent User Interface for Network Signal Optimization Programs
This paper presents the design philosophy and program intelligence used in EZ-TRANSYT and EZ-SIGOP, powerful multi-window input data managers for TRANSYT-7F and SIGOP-III, respectively....
