As population growth and urban development continue to expand in the coastal margin, flooding poses amajor threat to human safety and the integrity of the natural environment. To mitigate the adverseimpacts of coastal flooding, decision makers are increasingly advocating watershed or ecosystemapproaches to management. While it is argued that some of the most serious flood hazards are the resultof a failure to understand the regional ecological context, little empirical research has been done on howgrowth and development patterns increase the threat of floods at the watershed level and howcommunities respond over time to repetitive flooding events.My career plan will address this need by implementing an interactive research and educational programon flood mitigation, sustainable watershed management, and policy learning. It will develop a frameworkfor adaptive decision making for coastal flood hazards by integrating research, education, and informationdissemination. The research component will focus on the impacts of wetland development on coastalwatershed flooding and policy learning at the community level to mitigate the adverse impacts of flooddamage to the human and natural environment. A two-phase longitudinal research design will employboth quantitative and qualitative analyses to investigate flooding problems in Texas and Florida. Phaseone will use Geographic Information Systems (GIS) to examine the spatial pattern of wetlanddevelopment over a ten-year period and correlate this development with coastal watershed flooding.Phase two will identify thresholds of policy learning by examining how communities adjust and adapt torepetitive flooding. Both research phases will use multivariate analysis to measure the effects of wetlanddevelopment on flooding and the effects of flooding on policy adjustment while controlling forsocioeconomic, biophysical, and other contextual factors. The education component of the career planwill develop place-based learning modules on coastal watershed management and flood mitigation. Aseries of interdisciplinary, problem-based seminars will provide an authentic learning experience toprepare future scientists, teachers, and policy makers to address ecosystem-level hazards issues.Intellectual Merit of Proposed Plan The intellectual merit of the research is based on advancing knowledge of the causes of coastal watershedflooding and showing how to adapt policy mechanisms to mitigate floods. Results will contribute to adecision-making framework for flood mitigation by increasing understanding of the specific type, size,and location of wetlands that mitigate flooding and provide guidance to watershed planners for managingadaptively over time. This understanding is critical given the continued development of coastal areas andthe increasing vulnerability of human populations to coastal flooding. One of the unique features of theproposed research will be the utilization of data sources that have been underutilized in the analysis ofwetland loss. The national wetland permit and USGS flood gauge databases offer important opportunitiesto conduct an empirical study on watershed flooding.Broader Impacts of Proposed Plan While the project will contribute to scientific understanding and management capabilities, it will alsopromote teaching and learning on system-wide ecological problems. By building on participation in theUniversity.s NSF sponsored Informational Technology and Science Program and Sustainable CoastalMargins Program, the project will integrate research on watershed management and flood mitigation witheducation and training to solve these issues. Interdisciplinary, place-based learning modules will trainstudents and teachers to understand and act upon complex ecosystem management problems throughproblem solving, field experience, and the development of watershed case studies and associatedwebsites. Courses during the academic year will target graduate students, while summer sessions willalso include K-12 teachers. Another positive impact of the project will be recruitment and training ofstudents from underrepresented groups. These individuals will play a vital role in both the research andeducational components of the project. Finally, the dissemination of results will benefit the academic andpolicy making community. In addition to presenting research results at conferences and workshops, theinformation will be shared with public decision makers.

随着沿海边缘人口增长和城市发展不断扩大，洪水对人类安全和自然环境的完整性构成了重大威胁。为了减轻沿海洪水的不利影响，决策者越来越多地提倡采用流域或生态系统方法进行管理。虽然有人认为，一些最严重的洪水灾害是由于未能了解区域生态环境造成的，但对于增长和发展模式如何增加流域洪水威胁以及社区如何随着时间的推移做出反应，几乎没有进行实证研究。我的职业计划将通过实施关于防洪、可持续流域管理和政策学习的互动研究和教育计划来满足这一需求。它将通过整合研究、教育和信息传播，制定沿海洪水灾害适应性决策框架。研究部分将重点关注湿地开发对沿海流域洪水的影响以及社区一级的政策学习，以减轻洪水损害对人类和自然环境的不利影响。两阶段纵向研究设计将采用定量和定性分析来调查德克萨斯州和佛罗里达州的洪水问题。第一阶段将使用地理信息系统（GIS）来研究十年间湿地发展的空间格局，并将这种发展与沿海流域洪水联系起来。第二阶段将通过研究社区如何调整和适应重复的洪水来确定政策学习的阈值。两个研究阶段都将利用多变量分析来衡量湿地开发对洪水的影响以及洪水对政策调整的影响，同时控制社会经济、生物物理和其他背景因素。职业计划的教育部分将开发有关沿海流域管理和防洪的本地学习模块。一系列跨学科、以问题为基础的研讨会将提供真实的学习体验，帮助未来的科学家、教师和政策制定者做好准备，解决生态系统层面的危害问题。 拟议计划的学术价值 该研究的学术价值基于对成因的深入了解沿海流域洪水的影响，并展示如何调整政策机制来减轻洪水。研究结果将通过增加对缓解洪水的湿地的具体类型、大小和位置的了解，为缓解洪水的决策框架做出贡献，并为流域规划者提供随着时间的推移进行适应性管理的指导。鉴于沿海地区的持续发展以及人类对沿海洪水的脆弱性日益增加，这种理解至关重要。拟议研究的独特之处之一是利用了在湿地损失分析中未充分利用的数据源。国家湿地许可证和美国地质调查局洪水测量数据库为对流域洪水进行实证研究提供了重要机会。拟议计划的更广泛影响该项目将有助于提高科学理解和管理能力，同时也将促进对全系统生态问题的教学和学习。通过参与大学国家科学基金会资助的信息技术和科学计划以及可持续海岸边缘计划，该项目将把流域管理和防洪研究与教育和培训相结合，以解决这些问题。跨学科、基于地点的学习模块将培训学生和教师通过解决问题、现场经验以及流域案例研究和相关网站的开发来理解复杂的生态系统管理问题并采取行动。学年期间的课程将针对研究生，而夏季课程也将包括 K-12 教师。该项目的另一个积极影响是招募和培训来自代表性不足群体的学生。这些人将在该项目的研究和教育部分发挥至关重要的作用。最后，成果的传播将使学术界和政策制定界受益。除了在会议和研讨会上展示研究成果外，信息还将与公共决策者共享。
