Discussing channel degradation of Missouri River in Kansas City - Associated PressA 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 in elevation by 12-ft over the past 50-years requiring up to $4 million in improvements to pumps and water infrastructure to get drinking water from the river. A bigger concern to geotechnical engineers is the potential impact on bridge piers and levees. (Photo by Associated Press)

The causes of the degradation are not clear, but theories include upstream dams reducing the sediment coming downstream, efforts to channel the river, dredging, floods and other natural processes. Perhaps more details will surface in the draft Corps report.

A temporary micropile underpinning foundation system was used to support the abutments of the US 69 bridge over the Kansas River near Kansas City, KS while repairs to the abutment bearing devices were performed. This post is based on my notes from the presentation titled “Emergency Micropile Underpining of the U.S. 69 Truss – Kansas River Bridge” by Jim Brennan, Assistant [State?] Geotechnical Engineer with KDOT. It was the first presentation of the 34th Southwest Geotechnical Engineers Conference in Phoenix this week. Read on for more.

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. Read on for more info.
