The workshop consisted of four sessions: Corps perspective, hydrology, hydraulics, and modeling methods. Twenty-six papers were presented. The participants included representatives from the Corps and the USGS, private consulting industry, academia, and state and local agencies. The major objective of the workshop was to bring together software developers and users to discuss use of existing models, as well as the needs for future models. These proceedings are intended as a means of sharing the experiences of the participants in dealing with a variety of urban hydrology and hydraulics modeling issues. Ideally, lessons learned, or standard procedures could be extracted and converted into guidance for future urban work. Although there is a portion of urban hydrology for which this can occur, the varied nature of urban studies is such that creative, never-before-done solutions will always be needed. Therefore, summaries of the proceedings are included that attempt to draw together the quantifiable notions from the papers, while the papers themselves serve as a library of creative solutions to the unique elements in each study.

At least 124 of the confirmed 525 deaths were attributed to the tsunami. We examine factors that influenced losses from the tsunami. Chile's Servicio Hidrografico y Oceanografico de la Armada (SHOA) issued a tsunami warning about 11 minutes after the earthquake that was canceled shortly afterwards. Few coastal residents heard the warning or the cancelation due to widespread power outages, and the official warning had little impact on survival. Interviews with coastal residents showed a high level of awareness of natural tsunami warning signs. Coastal residents cited the importance of school and government education programs, tsunami evacuation drills, signs, the media, and informed local officials in their decision to evacuate. There were two notable failures: the vulnerability of transient populations and people in areas with no access to high ground. [DOI: 10.1193/1.4000033]
