Smoke Plumes From In Situ Burning of Oil Spills
Mesoscale pool fire experiments with effective diameters up to 17.2 m were conducted to obtain data on the characteristics of burning crude oil on water. These experiments showed that...

Engineering Tools and Techniques for Coastal Zone Management
In coastal zone development scheme, coastal engineers are confronted with a changing attitude towards human interventions in the coastal zone. Traditionally civil engineering has been...

Shoreline Management Along the Cohesive Shorelines of the Great Lakes
The primary focus of Shoreline Management Plans (SMPs) is minimizing the risks to life and property due to flood and erosion hazards. Various approaches are utilized to minimize these...

CANUSLANT?An Evolving-Marine Pollution Contingency Plan
The progress of CANUSLANT exercises to data is addressed in this paper. This exercise model can be used to initiate or improve Marine Pollution Contingency planning....

Rain Gage Network Size for Automated Flood Warning Systems
A methodology is presented that establishes a rational framework for estimating the optimum rain gage network size for flash flood warning systems based on network performance and economic...

Two-Dimensional Flood Hazard Simulation on Alluvial Fans
The incentive for flood hazard delineation on alluvial fans is development. Drainage plans and flood mitigation design require prediction of flow hydraulics for a range of hyperconcentrated...

Monongahela River Mapping & Flood Hazard Study
The study described here represents a unique collaboration and cost-sharing effort between two Federal agencies: the U.S. Army Corps of Engineers (USACE) and the Federal Emergency Management...

A National System for Threshold Runoff Estimation
Threshold runoff is the amount of effective (or excess) rainfall of a given duration uniformly distributed over a certain catchment that is just enough to cause flooding at the outlet...

Investigation of Chloroform Plumes in a Porous Media
A sand box model was used in the laboratory to study the development and stability of the contaminant plume with respect to space and time. Steady, uniform flow velocities were established...

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...

Lead is a Four-Letter Word
New regulations and strict enforcement make it difficult and expensive to remove lead-laden coatings from steel structures. Lead-based primers and paints are not considered hazardous as...

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...

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...

Debris Flow Velocity Estimation Methods for Natural Hazard Assessment
Debris flows are a special category of fluid and mass flow phenomena in which natural runoff entrains extremely high concentrations of sediment. The sediment-water mixture has properties...

San Francisco Bay and Delta Oil Spill Fate Studies Part I: Hydrodynamic Simulation
A two-dimensional vertically-averaged finite element model was used to simulate the hydrodynamics in San Francisco Bay and Delta to support oil spill fate studies. Simulations were performed...

San Francisco Bay and Delta Oil Spill Fate Studies Part II: Oil Spill Simulation
Because of the presence of oil refineries and significant tanker and barge traffic in the bay and delta region, the possibility of a moderate or major spill in the area must be considered....

Bureau of Reclamation Downstream Hazard Classification
An overview of the downstream hazard classification process used by the Bureau of Reclamation (Reclamation) and other U.S. Department of the Interior (DOI) agencies for the safety of dams...

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...

Research Needs for Debris Flow Disaster Prevention
A 'soft' disaster reduction strategy is proposed based on identification of hazard location, extent and maximum intensity; monitoring of antecedent catchment moisture, sediment and vegetation...
