SEAHIVE – Sustainable Estuarine and Marine Revetment

  Project Data
Funds: $119,174
Staff Responsibility: Inam Jawed
Research Agency: University of Miami
Principal Investigator: Landolf Rhode-Barbarigos
Fiscal Year: 2018

This project focuses on the design, analysis, fabrication, and testing of SEAHIVE, a novel modular, cost-effective yet efficient and ecofriendly shoreline protection system. Work in Stage 1 of the project will focus on defining the load applied on a SEAHIVE Element, given its perforated tubular shape, and optimizing the proposed design, considering criteria such as energy dissipation and stability as well as bio-diversity. SEAHIVE elements of various geometries will be instrumented with monitoring equipment and tested in the SUSTAIN tank under varying wave conditions. Performance will be quantified based on the measurements of pressure and current velocity landward on the models. Selected geometries of SEAHIVE elements will be tested in the SUSTAIN tank under varying wave conditions, considering different void configurations (i.e. shape and dimensions). Performance will be quantified based on the measurements of pressure and current velocity landward on the models. Concrete mix will be optimized for improved robustness against wave loads, easy constructability, and marine compatibility. Small-scale models composed of fiber reinforced concrete with non-corrosive reinforcements will be used to study the feasibility of prefabricated formworks. The design will be validated through experimental testing in the SUSTAIN tank. Work in Stage 2 will focus on the characterization of SEAHIVE system performance for different system configurations. Different system configurations (sets of elements) will be tested in the SUSTAIN tank under varying wave conditions to investigate parameters such as the element orientation, distance, and offset. The performance of the system will be quantified based on measurements of pressure and current velocity around the elements.
