Corps level data about Afghan security forces is not just classified — it is not reliably known, U.S. military officials have confirmed.
Many members of the Congress and the Senate have questioned the project, opposed federal financing and have called for an independent investigation of the corps' economic and environmental data for the project.
In Louisiana, of an estimated 60 million cubic yards of debris, about 32.7 million cubic yards of debris were picked up by early February, 18 million of them by contractors hired by the corps, according to FEMA data.
Data from the corps's Web site indicates that Lake Superior has almost reached its record low, set in 1926.
Greg Jacob, a former Marine infantry officer who is policy director for Service Women's Action Network, an advocacy group, said he was concerned that the corps might try to use data from the physical tests to prove that women are not strong enough to be infantrymen.
The corps responded by contending that the data used for the commission's study was incomplete.
According to data collected by the Corps and made public by Mr. Campbell, Route 92 would decrease traffic on local roads by as much as 40percentt for cars and 70percentt for trucks over the next 25 years.
The study argues that a change in the way water flows were measured, dating from the 1930s, mistakenly led the corps to make downward adjustments in data from the 1800s and early 1900s.
But Gary R. Dyhouse, a hydrologist who retired from the Corps of Engineers in 1999 but still consults for that agency on Mississippi flood questions, said the adjustments in the data made by the corps were correct.
In the 12 expeditions Burkholder had led so far, he and his usual corps of graduate students had obtained data on 59 sharks.
For all the new data, however, the levee system that the corps has been building is largely based on a model of a hurricane derived from data first collected in 1959.
