Storm surge model to help New Orleans

New Orleans was this week using a method of flood prediction developed by Dutch consultant Royal Haskoning as hurricane season began in the Gulf of Mexico.

Following 2005’s disastrous Hurricane Katrina, Royal Ha skoning designed and introduced a “Surge Atlas” flood modelling system for the city and its surrounding areas.

“With the time of year for hurricanes looming, everything is being arranged again to prepare New Orleans.”

A rapid assessment of the chance of overtopping and possible overflow can be made by combining the maximum water levels and wave heights calculated by the atlas.

The results can be used to plan and prepare for rescue and repair work. This information can also support decisions about whether or not to close the flood barriers around New Orleans.

“With the time of year for hurricanes looming, everything is being arranged again to prepare New Orleans,” said Royal Haskoning US vice president Mathijs van Ledden.
