High Resolution Flood Modelling based upon LAR-IAC data

A couple of years ago, Brett Sanders from UC Irvine partnered with LA County’s Department of Public Works to investigate the value of using high resolution LIDAR (evelation) data to model flooding.  They modelled the 1963 Baldwin Hills Dam Break, which caused extensive damage in Los Angeles.

To summarize, the process determined that high resolution data does improve the predictive abilities of their flood modelling systems.  At this point I would be interested in ideas that folks would have to fund the creation of a set of models for:

  • All of the dams in the County with a different set of water heights.
  • Tsunami inundation models based upon different scenarios.

With the County’s soon to be released Mass Notification providing a way to quickly contact people in danger, a better model for areas that will be impacted will help ensure that the information gets to the appopriate people first.  As well, it may be possible to use these models to more accurately determine FEMA flood zones, potentially saving County residents money on flood insurance requirements.
