Stark gives 2015 James M. Hoover Lecture at Iowa State University
Dr. Stark gave the 2015 James M. Hoover Lecture at Iowa State University on 12 March 2015. Dr. Stark discussed the two floodwall failures during Hurricane Katrina that inundated the Lower Ninth Ward and the recent federal court ruling in favor of the U.S. Army Corps of Engineers. The lecture described the extensive field and laboratory testing, 2D and 3D transient and unsaturated seepage analyses, and causation investigation used to show that underseepage did not cause either floodwall breach.

Stark elected Vice Chair of Embankments, Dams, and Slopes (EDS) Committee
Dr. Stark was elected Vice Chair of the EDS Technical Committee and will serve a three-year term from 2015 to 2018 under the new EDS Chair, Erik Loehr of the University of Missouri. The mission of the EDS Committee is to foster advancement of engineering practices and recognition of issues supporting safety of earthfill dams, levees, embankments, and slopes.

Stark receives 2014 Richard S. Ladd Standards Development Award from ASTM
Dr. Stark and his former Ph.D. student, Manzoor Hussain, were selected to receive the 2014 ASTM Richard S. Ladd Award for their revised test method titled: “D6467: Standard Test Method for Torsional Ring Shear Test to Determine Residual Shear Strength of Cohesive Soils” that was approved in 2013.

Lecture at Drexel University
Dr. Stark gave a lecture titled: “Landslide in Complex Geology” at Drexel University in Philadelphia on 7 August 2013. This presentation described a large landslide in Francisan Melange that impacted two housing developments.

Stark receives 2013 Thomas A. Middlebrooks Award from ASCE
Dr. Stark and his former Ph.D. student, Manzoor Hussain, were selected to receive the 2013 ASCE Middlebrooks Award for their paper titled: “Shear Strength in Preexisting Landslides” that was published in the July, 2010 issue of the Journal of Geotechnical and Geoenvironmental Engineering. This award recognizes a paper in the last year that “shall be judged worthy of special commendation for its merit as a contribution to geotechnical engineering”.

Katrina Floodwall Failures.
Dr. Stark, serving as one of a number of experts for the U.S. Government, provided important testimony regarding the cause of the two floodwall failures that inundated and devastated the Lower Ninth Ward in New Orleans. His testimony persuaded Judge Duval to write: “Dr. Stark presented compelling evidence which the Court accepts that the site specific permeability of the organic clay soil at the EBIA would result in it taking one minute to generate four teaspoons of water to flow through that clay (Trial Testimony of Stark at 3414). With this inexorable fact confronting Plaintiffs' experts, a shift in causation from water seepage to pressure as the primary cause of the uplift pressure and de-stabilization of the floodwall occurred.” Judge Duval ultimately ruled in favor of the U.S. Government and Washington Group International, Inc. in this important case.

Slope Stability Lecture in Wisconsin Landfill Design Course
Dr. Stark gave a lecture titled: “Slope Stability and Seismic Considerations” in annual short course in Madison on 22 February 2013. This presentation described stability analyses and case histories for various landfill conditions and slopes.
