Last-Mile Evacuation


Duration: May 2007 - April 2010

This research project develops a numerical last mile tsunami early warning and evacuation information system (acronym: “Last-mile – Evacuation”; sponsorship code: 03G0643A-E) on the basis of detailed earth observation data and techniques as well as unsteady, hydraulic numerical modelling of small-scale flooding and inundation dynamics of the tsunami including evacuation simulations in the urban coastal hinterland for the city of Padang, West Sumatra, Indonesia. It is well-documented that Sumatra’s third largest city with almost one million inhabitants is located directly on the coast and partially sited beneath the sea level, and thus, is located in a zone of extreme risk due to severe earthquakes and potential triggered tsunamis. “Last-Mile - Evacuation“ takes the inundation dynamics into account and additionally assesses the physical-technical susceptibility and the socioeconomic vulnerability of the population with the objective to mitigate human and material losses due to possible tsunamis. This project is being developed in close cooperation with the local authorities of Padang, the Engineering Faculty of the Andalas University in Padang as well as the Indonesian research institutions. Thus, by means of modelling tsunami inundation scenarios as well as performance of evacuation processes a crucial disaster preparedness measure is made available.

The work load towards the research project objectives is divided into five work packages, based on field of expertise of each working partner, namely socio-economic vulnerability assessment (WP 1000), inundation scenarios, flow analysis (WP 2000), geodatabase, information system and vulnerability assessment (WP 3000), evacuation analysis and pedestrian traffic optimization (WP 4000) and highly-resolved 3D-model of Padang (WP5000). On the basis of satellite images and other data sources, advanced highly resolved information including topography, infrastructure, population density and settlement structures are provided.
