This essentially points to the complete breach of the floodwall that would follow the formation of the crack (or water-filled gap), as had happened at a certain point along the 17th Street Canal. The results of this study also demonstrate another major error on the side of the USACE: the penetration depth of the sheet piles. According to the centrifuge model tests carried out on the model of the Orleans Avenue Canal North and the London Avenue Canal, when the canal levels were increased from normal levels to Katrina flood level there was a small movement of the wall [Ubilia]. However, when the water level was held at Katrina levels for a long period of time, there was no further movement of the wall, and the levee remained stable. The level was then increased to one near the top of the floodwall, which caused movement of the wall and the formation of a crack. However, there were no failure of the levee was reported. So, we know that there was a failure of the 17th Street Canal, but none with the Orleans Avenue Canal North. The difference in the structure of these two canals were that the sheet pile penetration depth of the Orleans Avenue Canal North was greater than that of the 17th Street Canal. This is a prime example of negligence on the part of the U.S. Army Corps of Engineers. Further research into this matter reveals that this is actually the result of a misinterpretation of the results of a study carried out by the Army Corps of Engineers into the penetration depth of
