Example Community A:   Owase, Japan

Site Overview
Characteristics:	Densely populated site in a low-lying area, bounded by land of higher elevation on three sides. Several major rivers empty into the adjacent embayment, which is roughly rectangular (2 km wide by 4 km long). Coastline is rugged, with several small pocket beaches (300-400 m wide) along the north and south shores. Many small islands are included in the data (but could be removed).
Features of interest for tsunami models:	Structures include power plant, oil storage tanks, offshore terminal jetty, fishing port with quay and breakwater. Seawall present on a large parcel of land located at the head of the basin, protecting an industrialized area. Bridges span the three major rivers located at the head of the embayment. Wide variety of buildings, from small residences to large commercial buildings. Roads are narrow and form a complex network.
Available Data
Topography grid:	Grid size is 50 m (can be refined to approximately 5 m); based on LIDAR.
Bathymetry grid:	Not available as GIS layer
Other GIS layers:	Roads, rivers, political (city/town/village) boundaries, geographic (sea/river/land) boundaries, building location and size, location of seismic sensor; locations of individual inhabitants
Issues:	Bathymetry data is needed. Additional detail on building structures (type of structure, use, and construction) is highly desirable.
Potential Uses
Once additional data are incorporated into the current database, the following simulations could be performed: complex tsunami patterns within the embayment (there is a potential for a tsunami-induced resonance within the 4km long embayment); tsunami effects on the pocket beaches and local headlands; tsunami overtopping of breakwaters and jetty; tsunami propagation along the rivers; effects of tsunami actions on buildings, bridges, tanks and other objects; overland flows at the power plant site; behavior of floating bodies such as fishing boats; simulations for local warning transmission, human behaviors and evacuation strategies; rescue tactics and mitigation planning
