Flow and Transport of Nonaqueous Phase Liquids in Groundwater Systems
Nonaqueous phase liquids (NAPLs) are present at numerous hazardous waste sites and are suspected to exist at many more. Due to the numerous variables influencing NAPL transport and fate...

Adaptive Control of Unavoidable Hazardous Releases
This paper presents a procedure for the adaptive control of hazardous releases of toxic substances. In particular, the control strategy is aimed at deliberate releases from man-made storage...

Reducing the Potential Downstream Impacts of a Dam Failure
The dam safety regulations imposed by the individual states in the United States vary widely and provide inconsistent protection for the citizens of different states. The proximity of...

Disaster Reduction in Dam and Reservoir Design
Disaster reduction for small- and medium-sized reservoir projects is considered for two specific types of dam failure: 1) during extremely high floods, and 2) when severe reservoir silting...

Uncertainties of Tailwater in an Inundation Study: Dam Upgrade Optimization for Hazard Reduction
When an upgrade is required for a dam with an inadequate spillway system, the potential impact of tailwater during an extreme storm in an inundation study should be considered. This paper...

Hurricane Andrew in South Florida: Preparing a Water Management System for Disaster
This paper analyzes Hurricane Andrew from its beginning as a tropical storm to the powerful force that it later became. The careful monitoring that took place throughout its transformation...

Using Threat to Life Studies to Guide Dam Safety Decisions
Ensuring that Bureau of Reclamation (Reclamation) dams do not present unacceptable risks to public safety, prosperity, and welfare serves as a primary objective of Reclamation's Safety...

Reclamation's Design Process of Early Warning Systems for Dam Safety
This paper discusses the Bureau of Reclamation's process for designing the detection and decision making components of an Early Warning System (EWS) for dams with hydrologic deficiencies....

Extreme Events and Coastal Wetlands
Temporal ecosystem behavior in tidal wetlands can be static, dynamically stable, progressively changing, or subject to catastrophic change during extreme events. Catastrophic change in...

Interpreting Debris-Flow Hazard from Study of Fan Morphology
The deposits, stratigraphy, and surface morphology of debris-flow fans are a record of past debris-flow activity, and as such can provide useful information about debris-flow hazards....

Mapping Debris-Flow Hazard in Honolulu Using a DEM
A method for mapping hazard posed by debris flows has been developed and applied to an area near Honolulu, Hawaii. The method uses studies of past debris flows to characterize sites of...

Debris Flow & Hyperconcentrated Flow: A UK Perspective
Debris-flow activity within the UK is largely confined to upland regions and certain coastal locations. Within the uplands, debris-flow and hyperconcentrated flood waters pose a local...

Structural and Non-Structural Debris-Flow Countermeasures
Debris-flow can potentially occur for almost any torrents whose gradient is steeper than a given critical value and the frequency at which the debris-flow occurs depends on geological...

A GIS-Based Rail Infrastructure Management System
Computer-based models and analytical techniques are powerful components of infrastructure management systems. However, the availability of data sets significantly affects the usefulness...

Use of Hazard Analysis in Maintenance

Ground Penetrating Radar: Images of Subsurface Characteristics
Ground penetrating radar has not been widely used for subsurface exploration in Civil Engineering. This paper describes the experimental setup used to explore ground penetrating radar...

Non-Destructive Remote Sensing of Hazardous Waste Sites
This paper describes how the non-contact, nondestructive, remote sensing techniques, of Computer Enhanced Infrared Thermography and Ground Penetrating Radar, may be used to detect buried...

Hydraulic Engineering
This proceedings, Hydraulic Engineering, contains papers presented at the 1993 National Conference on Hydraulic Engineering held in San Francisco,...

Disaster - Recovery Planning

Assessment and Prediction of Debris-flow Hazards
Study of debris-flow geomorphology and initiation mechanism has led to better understanding of debris-flow processes. This paper reviews how this understanding is used in current techniques...
