Despite some sand boils found along the Mississippi River, Gen. Martin Dempsey, the Army’s chief of staff, said “the levee system has done its job, up and down this river.” Mike Stack, the chief of […]
A forthcoming draft study by the Army Corps of Engineers will hopefully shed light on an ongoing problem of stream bed degradation along the Missouri River. Portions of the river in Kansas City have dropped […]
[Update 2/10/08] Updated the name of the bridge. [/Update]
DelDOT is putting the new Indian River Bridge over out to bid. The current bridge is said to be in danger of failing between 2008 and 2012 according to the Army Corps of Engineers, seems to be related to scour. From what I hear, the tidal currents at that inlet being spanned over are tremendous, with water velocities on the order of 35 mph.
In 2005, Mactec, a geotechnical firm, provided a geotechnical report and associated recommendations to DelDOT for how to construct the 45-ft high approach embankments for a 1,400-ft long bridge in light of a 60-ft clay layer (sounds like pre-loading). However, the embankments are not settling as Mactec predicted (not sure if its more or less, probably less meaning slower) and are "shifting laterally" (squeezing?) so the DOT is going with a longer bridge to span the problem soil. More after the break.
Vicksburg, Miss. – The Interagency Performance Evaluation Task Force (IPET) reaffirmed today that the New Orleans-area risk maps released on June 20, 2007, are correct. A data error discovered in the draft technical supporting documentation released by IPET on Nov. 7 raised questions about risk map accuracy for two sections of New Orleans.
The Mosul Dam in Iraq is in danger of an "imminent collapse" according to a Washington Post article. The dam threatens the lives of as many as 500,000 people in Mosul which could be innundated by over 60-ft of water if the dam fails. Parts of Baghdad could see as much as 15-ft of water.

The American Society of Civil Engineers ASCE sent a cease and desist letter to the owner of the Levees.Org website notifying them to remove a video spoof of its post-Katrina levee inspection. Of course, through the wonders of the internet, Levees.org removed it from YouTube, but someone else posted it again. And because of all the fuss, it’s more popular than it would have been otherwise with over 16,000 views at the time of this post. Click through to watch it.
WASHINGTON, DC, [Editor] September 24, 2007 [/Editor] – The Senate today passed the conference report for the Water Resources Development Act (WRDA) of 2007.
