Coastal Emergency Risks Assessment (CERA) Storm surge and wave guidance tool for emergency managers

Transcription

1 Coastal Emergency Risks Assessment (CERA) Storm surge and wave guidance tool for emergency managers Overview: Emergency managers seek visualiza0ons and geographic data to evaluate the impact of a storm or to see the surge and wave condi0ons on a daily basis. The most sought- aner informa0on comes both from real- 0me measurements like water level or precipita0on sta0ons and from ocean models that aoempt to predict the storm surge or the wave and 0de condi0ons. One of the most sophis0cated ocean models is ADCIRC, a mul0- scale, mul0- physics coastal circula0on model used to predict the effects of large storms approaching the coast. The CERA project brings the ADCIRC model results directly in the hands of the end- users (emergency managers, weather forecaster, GIS specialists) by providing a web- based, interac0ve Storm Surge Visualiza0on tool.

2 Transi?on to End- Users: Interac0ve website CERA (hop://coastalemergency.org ) Proved to be a successful and efficient tool for the presenta0on of ADCIRC model results Presents real- 0me results overlaid with emergency- relevant informa0on Allows to select several ADCIRC layers (water height, inunda0on, wind speed) Zoom in func0onality Has been designed to be an intui0ve- to- understand tool for the scien0fic community, emergency managers, and decision makers. 3 CERA websites: Atlan0c Coast (hop://nc- cera.renci.org) Northern Gulf (hop://cera.cct.lsu.edu) Professional (hop://cera- pro.cct.lsu.edu)

5 Development Year 7: Shapefiles: A shapefile is a geospa0al vector data format for Geographic Informa0on System (GIS) sonware. This data format replaces the raster data format that CERA used in the previous years. The shapefiles will be downloadable. CERA will also provides the original data in the NetCDF format ready for download. Reason: Emergency managers and GIS specialists do not only want to see the results but also want to use the data.
