113. Fitzgerald et al continue (Figure 10):
“Conceptual model for lateral displacement of the interdistributary deposits into the MR-
GO channel excavation due to overburden loading and the high-angle of channel walls
as built by the USACE. This phenomenon was predicted prior to construction by USACE
(1958) and resulted in the need for continual channel maintenance dredging as noted in
USACE (1976). The migration of sediments into the channel from the underlying
interdistributary deposits results in subsidence of the land surface and increases rates of
landloss along the channel. Waves produced by wind and the passage of large
oceangoing vessels accelerate the rate of bank failure and landloss within the marsh
deposits.”

Date : 27 January 2009 Subject : Comparison flood depth development between Katrina event and Scenario 2C From : ir. B. Maaskant, dr.ir. M. Kok To : Joe Bruno Comparison flood depth development between Katrina event and Scenario 2C The flooding of the bowls in New Orleans has been simulated with the use of the 1D2D flood simulation program SOBEK, see Kok et al. (2007). In that report three bowls have been distinguished, the Orleans Metro bowl, the New Orleans East bowl and the Saint Bernard bowl. For the three bowls flood simulations are constructed. Following on that report this memorandum will present the flood depth development over time for five specific locations. These locations are all situated in the Saint Bernard bowl (figure 1). In the table and picture below the five locations are shown. Table 1: The five considered locations

Because the locations ‘Lattimore & Associates’ and ‘Kent Lattimore’ are close together and the 50 by 50 meter grid that is used in the simulations these two locations will be considered as one.

In our model simulations no overtopping occurs before 7:00am, and the two breaches start at 7:00am. Therefore no water, except rain water, prior to 7:00am is visible inside the Lower 9th Ward in the simulation results. ILIT gives an alternative explanation for the early water mentioned by eye witness reports in IPET. ILIT mentions under seepage, water migrating from the channel, under pressure, beneath the IHNC floodwalls as a possible explanation for the early flood water in the Lower 9th Ward. Under seepage through a levee is not captured in the simulation.

Figure 5.2 Progressing snapshots of the computed internal flooding water depth inside the St. Bernard bowl Figure 5.2 shows the calculated maximum internal flooding depths in the St. Bernard bowl as a consequence of the breaches and overtopping initiated by hurricane Katrina. Figure 5.4 shows the comparison between our computed internal flood hydrographs and those presented by IPET for the St. Bernard bowl. The locations of the hydrographs are indicated in figure 5.1, location A corresponds with Lower 9th Ward NW., B with Lower 9th Ward E. and C with Chalmette. IPET based its hydrographs on eye witness accounts, stopped clock times and time/date stamped digital photographs. Our computed flood hydrographs are very similar to the data presented by IPET. The predicted peak flood level is within a foot of IPET’s measurements. The peak in the model is a couple of hours earlier and the water level starts to decrease earlier than in the IPET hydrographs. The final water descent rate in the model is about equal to the IPET hydrograph. As discussed previously, in extreme events such as Katrina is difficult if not impossible to get direct measurement of some input data such as water levels at the time of a breach, especially right at the breach location. However, the differences between the computer model results and the calibration data are fully acceptable. For the purpose of this study the model results are very credible.
