TRB’s National Cooperative Highway Research Program (NCHRP) Report 611: Seismic Analysis and Design of Retaining Walls, Buried Structures, Slopes, and Embankments explores analytical and design methods for the seismic design of retaining walls, buried structures, slopes, and embankments. The Final Report is organized into two volumes. NCHRP Report 611 is Volume 1 of this study. Volume 2, which is only available online, presents the proposed specifications, commentaries, and example problems for the retaining walls, slopes and embankments, and buried structures.

Possible Seepage at Newly Constructed New Orleans Levee
Wet spots have been detected along a portion of a new levee being constructed by a US Army Corps of Engineers Contractor. The levee is approximately 95% complete, but the Levee Board wants to establish what is causing the apparent seepage before accepting the levee. More after the break.
