CHL is responding to Katrina-related requests from our sponsors and stakeholders. Our responses are currently geared towards hindcasting and forecasting.
CHL is developing models for the forensic analysis of waves, water levels, water quality, and other aspects of the storm for Lake Ponchartrain, New Orleans, Southeast Louisiana, and coastal areas east, southeast, and south of New Orleans. This effort also involves data collection of many types.
Our forecasting efforts are geared toward examining problems that could arise from the dewatering efforts in New Orleans. Our modeling capabilities will aid as decisions need to be made concerning contaminants, bacteria and various pollutants as well as concerning other water quality issues.

- Corps: Foundation Problem in Levees Blamed
Associated Press - March 10, 2006 - A foundation problem — although not the one targeted by earlier studies — caused the 450-foot-long break in a floodwall and levee on New Orleans' western edge when Hurricane Katrina hit, the U.S. Army Corps of Engineers said Friday.
- National Public Radio - Army Builds Mini New Orleans to Study Levees
All Things Considered, March 9, 2006 - The U.S. Army Corps of Engineers will release a report Friday detailing its version of how the New Orleans levees failed. As part of the study, engineers built a miniature scale model of the city at a Mississippi laboratory to simulate events of the flood.
- National Public Radio - Model Attempts to Recreate New Orleans Levee Failure
Morning Edition, March 6, 2006 - A team of engineers assembled in a Vicksburg, Miss., laboratory on Sunday to watch a centrifuge spin a tiny model of a New Orleans canal. The experiment was an attempt to recreate, on a smaller scale, the failures of the city's levee system during Hurricane Katrina.
- National Public Radio - Scale Model Aids Probe of Katrina Damage
Day to Day, February 16, 2006 - The Army Corps of Engineers is building a scale model of a part of New Orleans that suffered levee failure during Hurricane Katrina. Madeleine Brand talks to Ira Flatow, host of NPR's Science Friday about what engineers hope to learn.
- Louisiana Coastal Protection and Restoration (LACPR) Project - Congress has directed the Corps of Engineers, New Orleans District, in partnership with the State of Louisiana, to initiate a 24-month endeavor, the Louisiana Coastal Protection and Restoration (LACPR) Project. The project will identify, describe and propose a full range of flood control, coastal restoration, and hurricane protection measures for South Louisiana.

- NOAA HURRICANE KATRINA SUPPORT ACTIVITIES; Aerial Photography Flights Yield Thousands of Images
The day after Hurricane Katrina made landfall on the U.S. Gulf Coast NOAA began aerial photography flights of the affected areas. For nine days the NOAA Cessna Citation aircraft flew two to three missions each day only stopping to re-fuel. Nearly 7,000 aerial images were produced from these missions. NOAA also is providing a variety of support activities for areas affected by Hurricane Katrina.
- NOAA Hurricane Hunter Pilot Captures Katrina At Her Meanest
Sept. 1, 2005 - NOAA hurricane hunter WP-3D Orion and Gulfstream IV aircraft conducted ten long flights into and around the eye of Hurricane Katrina. Lt. Mike Silah, a P-3 pilot, got to see Hurricane Katrina up close and personal, especially when she was an extremely dangerous Category Five storm in the Gulf of Mexico. The day before the powerful and destructive storm made landfall on the USA Gulf Coast, Silah snapped a series of images capturing the eyewall of Katrina.
