The objective of this paper is to present the results of on-going field studies to assess the performance of geotextile sand-filled container (GSC) reinforced dunes and to develop probabilistic fragility curves for a range of damage states to these structures. While numerous lab experiments and numerical models have been developed to predict the hydraulic stability of coastal revetments made of GSCs, there has been limited in situ validation of these systems, especially when they are used to reinforce the core of a natural system (Dassanayake and Oumeraci, 2012). Furthermore, the formulas and nomograms developed to characterize GSC systems are not intuitive for coastal community stakeholders to assess the level of resiliency provided by a beach and GSC dune system. The development of fragility curves offers a solution to assess the performance and understand the tradeoffs of reinforced dunes for coastal protection systems.

CDR Fleischmann joined the faculty at USCGA in 2004 and was selected as a member of the Permanent Commissioned Teaching Staff in 2009. Her research focuses on mitigation of impacts of stormwater in the urban environment and undergraduate engineering education. While at the Academy, she has been an assistant coach on the men's and women's swim teams, faculty affiliate for the women's softball team, advisor for numerous clubs, and a member of the faculty senate. Prior to joining the Coast Guard Academy faculty, CDR Fleischmann was assigned to the U.S. Coast Guard Cutter Elm where she served two tours: as a Deck Watch Officer and Assistant Navigator and as the Operations Officer. In 2001, CDR Fleischmann became a member of the Facilities Engineering Branch at the USCGA. During this tour, she served as both the Safety Officer and the Construction Officer where she was the Contracting Officer's Technical Representative (COTR) as well as Civil Engineering Project Manager for the Academy's $5.2 million dollar construction program including all aspects of the construction process: cost estimation, general scopes of work, management of change orders and contractor evaluations.
