Modal Filter Based Structural Control of a Highway Bridge
An Adaptive Modal Filter (AMF) algorithm is developed which uncouples complicated multi-mode structural dynamic response into simple single-mode response. The application to active structural...
Procedures for Evaluating the Effects of Sedimentation on Flood Hazards in Urbanized Areas in the Southwestern U.S.
Urbanization of watersheds in the arid Southwestern U.S. creates problems for resource agencies and design engineers. Traditional analytical techniques that are generally applicable to...
San Diego County Water Authority's Emergency Storage Project Supplying Water During Natural Disasters
The San Diego County Water Authority (Authority) is developing the Emergency Storage Project (ESP) to improve the dependability of the County's water supplies during a natural disaster...
Flood Control vs. Flood Management
For the last 130 years, flood policy in the U.S. has been dominated by the belief that floods can be controlled by structural methods, such as levees, dikes and embankments. These efforts...
Graphical-Based Productivity Transient Investigation Using DISCO
Construction operations involve complex resource interactions and are typically performed in the field with exogenous factors such as inclement weather conditions and equipment breakdowns....
Development of an Expert System to Identify Hazardous Highway Spots
The paper describes the development of an expert system within a geographic information system to identify high-hazard spots in a highway network. The philosophy guiding expert system...
An Interactive Computer Code for Generations of Artificial Earthquake Records
A new interactive computer code is presented in this work for the calculation of artificial earthquake records that comply with any arbitrarily specified target response spectra or power...
Using Pen Computers in Post-Disaster Insurance Claim Settlements
The advanced use of pen computers for insurance claim damage assessment and settlement are explored. The advantages of implementing such a paperless approach to insurance claim settlements...
Uncertainty and Time Preference in Shore Protection
From a review of economic, psychologic, and geographic literature, three points of criticism of the economic model of choice are 1) when faced with losses, individuals tend not to be averse...
Flood Loss Assessment with Integrated Measures
In most cases, the maximum flood loss reduction can be achieved only by an optimal combination of both structural and nonstructural measures. An integrative approach that combines the...
Risk Management Strategies for Natural, Manmade, and Technological Hazards
The paper summarizes the fourth session of the conference which discussed risk assessment approaches in bio/chemical hazards; specific studies on people's behavior and views of natural...
Environmental Effects of Flooding at a USCG Base
In July of 1993, the U.S. Coast Guard (USCG) Base St. Louis facility was flooded. As the flood waters receded and cleanup efforts were initiated, a number of environmental issues had to...
The Use of Piezoelectric Film in Cavitation Research
A research program was conducted at the St. Anthony Falls Hydraulic Laboratory to investigate impulse pressures caused by the collapse of transient cavitation bubbles. The impulse pressures...
Benefits of Hazard Mitigation Planning to Reduce Shoreline Impacts Due to Great Lakes Water Level Management Fluctuations and Severe Storms
Recent experience with flood hazard mitigation planning that encompassed aspects of pre-disaster preparedness and recovery operations have proven to be an effective tool in geographic...
Laplace Valve Stroking for Complex Piping Systems
LaPlace valve stroking to control water hammer is applied in complex piping systems with friction and without friction. Two types of system are analyzed. The law of operation of the valves...
Problems of Stream Flood Simulation and Prediction
The article presents a report on the natural flooding in a stream and the problems encountered when simulating and predicting stream floods. The complexity of flood characteristics, the...

Is It Ethical to Profit from a Natural or Man-made Disaster?
When a natural disaster occurs, should engineers charge their usual fees? The winner of the Daniel W. Mead Prize for Younger Members addresses some ethical aspects of this question using...
Guidelines for the Development of Natural Phenomena Hazards Design Criteria for Surface Facilities
This paper discusses the rationale behind the guidelines, criteria, and methodologies that are currently used for natural phenomena hazard design and evaluation of DOE nuclear and non-nuclear...
