SBIR Phase II: A nature-based nearshore floating infrastructure solution for coastal adaptation

SBIR第二阶段项目的更广泛影响是帮助管理沿海城市的环境变化。目前，在沿海基础设施社区存在一个有效的解决方案，支持生态健康和社区为基础的共同利益超过传统的灰色基础设施，如海堤，护堤，或结构化填充的差距。该项目通过一个新的全面试验性实施一个可靠和持久的基于生物质的沿海保护浮动模块网络来解决这一差距。拟议的项目开发了一个动态的，面向细节的科学方法和技术建模。该项目将展示一个相互连接的、锚定的生物质模块网络如何抑制波浪能、吸收水污染物并为沿海城市创造一个吸引人的社区空间。SBIR二期项目的技术创新是：（A）基于生物质和活植物的适航漂浮模块的新材料工程方法，锚定在六边形阵列中并相互连接;（B）一个完整的数值预测模型套件，用于模拟大型模块网络的地球化学效应、流体动力学网络效应和流体动力学效应;以及（C）一个全功能原型网络，用于研究物理行为和效应。该项目包括五个独立的实验目标：（1）广泛的单元原型设计、重新设计和监测，以评估制造商材料和生物行为随时间的变化，（2）对单个单元和网络影响的生态监测，导致预测性生物地球化学模型的开发，（3）将物理波浪槽实验室结果转化为预测性沿海环境模拟模型，（4）全尺寸实验网络原型的流体动力学分析，以及（5）大规模生产和部署的技术方法的开发。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

The broader impact of this SBIR Phase II project is to help manage environmental change in coastal cities. Currently, a gap exists in the coastal infrastructure community for an effective solution that supports ecological health and community-based co-benefits over traditional gray infrastructure, such as seawalls, berms, or structured fill. This project addresses that gap through a novel full-scale experimental implementation of a reliable and durable network of floating biomass-based modules for coastal protection. The proposed project develops a dynamic, detail-oriented scientific approach and technical modeling. This project will demonstrate how an interconnected, anchored network of vegetated biomass modules can dampen wave energy, absorb water pollutants, and create an engaging community space for coastal cities.The technical innovations of the proposed SBIR Phase II project are: (A) a new material engineering approach for seaworthy floating modules based on biomass and living plants, anchored in a hexagonal array and interconnected; (B) a full numerical predictive modeling suite to simulate biogeochemical effects, fluid dynamic network effects, and hydrodynamic effects of large such networks of modules; and (C) a fully functional prototype network to study physical behavior and effects. This project consists of five separate experimental objectives: (1) extensive unit prototyping, redesign and monitoring to assess manufacturer material and biological behavior over time, (2) ecological monitoring of individual unit and network impacts leading to the development of a predictive biogeochemical model, (3) translation of physical wave tank lab results into a predictive coastal environment simulation model, (4) hydrodynamic analysis of a full-scale experimental network prototype, and (5) development of technical methods for production and deployment at scale.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
