Rapidly Deployable Armoring System for Temporary Protection of Earthen Levees during Overtopping

The objective of this thesis was to develop guidance for an anchored geotextile Rapidly Deployable Armoring System for the landward side of earthen levees to mitigate the effects of storm surge and overtopping waves. A case study of the Backwater Levee protection placed during the 2011 Mississippi River flood by the US Army Corps of Engineers was performed to prove construction feasibility. Full scale anchor testing was performed for 0.3 and 0.6 m rod shaped anchors to determine their load deflection behavior. Anchor test data and shear stress profiles based on flume testing presented in literature were used in conjunction with surface to surface contact interactions to develop a single-layer elastic membrane finite element model (SLEMM) of an RDAS to provide design guidance. The SLEMM appears to perform the finite element formulations correctly, but does not produce physically meaningful results. Further improvements to the model are needed for useable design.
