The overall intent of this research is to develop numerical models of erosion of levees, dams and embankments, validated by physical models. The physical models are performed at 1-g and at high g’s using a geotechnical centrifuge. The erosion is modeled in detail, from beginning to end, that is from the time the levee is overtopped until the levee is breached. Typical quantities measured as a f...

Performance-based earthquake engineering (PBEE) provides a robust alternative to traditional design. PBEE enables engineers estimate expected damage, repair costs, and economic losses due downtime for candidate design, potentially leading novel new designs or retrofit solutions. With the increasing application of light-frame structural systems, such as cold-formed steel (CFS) panels, in residen...

The Strategic Foresight Initiative (SFI) is a collaborative effort of the emergency management community facilitated by the Federal Emergency Management Agency (FEMA). SFI was launched so the emergency management community can seek to understand how the world is changing, and how those changes may affect the future of emergency management. Participants in SFI have identified nine drivers that a...

We investigate tropical cyclone wind and storm surge damage reduction for five areas along the Miami-Dade County coastline either by hardening buildings or by the hypothetical application of wind-wave pumps to modify storms. We calculate surge height and wind speed as functions of return period and sea surface temperature reduction by wind-wave pumps. We then estimate costs and economic losses ...

SUPPLEMENTARY INFORMATION: The Federal Emergency Management Agency (FEMA) publishes proposed determinations of Base (1% annualchance) Flood Elevations (BFEs) and modified BFEs for communities participating in the National Flood Insurance Program (NFIP), in accordance with section 110 of the Flood Disaster Protection Act of 1973, 42 U.S.C. 4104, and 44 CFR 67.4(a). These proposed BFEs and modifi...

During the 2005 Atlantic hurricane season, Hurricane Katrina wreaked havoc on New Orleans. Significant damage to the Gulf region forced the Federal Emergency Management Agency (FEMA) to begin an unprecedented cleanup effort. The removal and disposal of debris was not only a challenge for landfill capacity but also for the administration of drivers, trucks, and debris type. With the debris remov...

Bukit Tinggi may experience low earthquake hazard but are still at high risk of substantial damage and loss. Dense concentration of buildings and infrastructure in some areas mainly due to the hospitality industry can generate this high risk level. This study is focused on identify, inventory and rank buildings in Bukit Tinggi to assess seismic vulnerability buildings. The methodology is based ...

The Federal Emergency Management Agency (FEMA) has identified the four phases of disaster related planning as mitigation, preparation, response, and recovery. The recovery phase is characterized by activity to return life to normal or improved levels. Very little research considers the recovery phase, which encompasses restoring services and rebuilding disaster stricken areas of the highway tra...
