CNH-L: Coastal Processes and Human Response to Shoreline Change

一种解释项目意义和重要性的非技术描述。海岸线受到一系列复杂的物理过程的影响。此外，人类对海岸变化的反应是复杂且往往相互关联的决定的结果。该项目将开发一套综合模型，以更好地了解在不同地质环境、气候变量（如波浪和风暴影响）、发展情景、法律和监管制度以及海岸保护或应对战略下发达海岸线演变的动态。开发和沿海过程之间长期动态相互作用的模型将有助于预测发达的海岸线如何应对气候条件变化引起的海平面上升、侵蚀和淹没所造成的未来变化。马萨诸塞州和新泽西州海岸的两个例子被选为测试案例，因为这两个地方在海岸保护方面有着悠久的发展历史和尝试，跨越了不同的地质和风暴气候环境。该项目将制定一个正在进行的短期课程，向沿海土地管理人员通报主要发现和应用情况。该项目将提供新的工具和信息，以提高对地质框架、地貌过程、人类海岸线保护措施的经济学以及由于气候驱动的外生效应（如海平面上升）如何改变已开发的海岸线动力学之间的沿岸耦合相互作用的认识。模型结果将纳入一个现实的政策框架，为在沿海细胞规模上以经济有效和可持续的方式管理海岸线资源提供指导。这项工作将推动沿海变化响应气候变化影响的形态动力学模型的发展，并将地质模型与经济后果和人类行为的模型相结合。多学科项目团队包括地貌学家、政策和经济科学家以及法律专家，他们在涉及人类干预的沿海演变的综合地缘经济模型方面有着成功的合作历史。

A non-technical description of the project that eplains the significance and importanceCoastlines are influenced by a complex set of physical processes. In addition, human response to coastal change is a result of complicated and often interlocking decisions. This project will develop a set of integrated models to better understand the dynamics of developed shoreline evolution under different geologic settings, climatological variables such as wave and storm influence, development scenarios, legal and regulatory regimes, and strategies for coastal protection or response. The models of the long-term dynamic interactions between development and coastal processes will be useful to project how developed coastlines may respond to future alterations due to sea-level rise, erosion, and inundation that are caused by changing climate conditions. Two examples from Massachusetts and the New Jersey coasts are selected as test cases since both have long histories of development and attempts at coastal protection that span different geologic and storm climate settings. The project will develop an ongoing short course that will inform coastal land managers of the major findings and applications.A technical description of the projectThis project will yield new tools and information to improve knowledge of the alongshore-coupled interactions among the geological framework, geomorphic processes, the economics of human shoreline protection measures, and how developed shoreline dynamics may change due to climate-driven exogenous effects, such as sea-level rise. Model results will be integrated within a realistic policy framework to offer guidance on economically efficient and sustainable ways to manage coastline resources at the scale of the littoral cell. The work will advance the state of the art in morphodynamic models of coastal evolution in response to climate change effects and the integration of geologic models with those of economic consequences and human behavior. The multi-disciplinary project team includes geomorphologists, policy and economic scientists, and legal experts who have an established history of successful collaborationwith integrated geo-economic models of coastal evolution involving human interventions.
