EAGER: INVESTIGATING DRIVERS OF STORMWATER FLOODING IN COASTAL COMMUNITIES: A CITIZEN SCIENCE PROJECT

CBET 1644650（Etheridge）该奖项是根据NSF的主题公众参与科学研究。调查人员将通过调查北卡罗来纳州的屏障岛博格班克斯风暴事件后洪水的驱动因素，评估公民科学家收集的数据的可靠性、有效性和可信度。该项目将招募40名公民科学家，以（a）记录容易遭受暴雨洪水的地区，（B）在三个月内测量和记录沿海社区的地下水和地表水水位。公民科学团队将在威尔斯井中部署20个自动水记录仪，以收集独立的地下水数据，并与公民科学家收集的数据进行比较。公民科学家还将被要求确定容易发生暴雨洪水的地区，调查人员将在那里安装工作人员测量仪，以测量暴雨事件期间的地表水积水。公民科学家的任务是记录水位，并使用智能手机或其他设备拍摄洪水地区的水位计照片。然后，研究人员将使用图像处理/机器视觉软件从照片中提取定量数据，以与公民科学家记录的数据进行比较。地下水模型将用于模拟地下水位波动对暴雨洪水事件的影响。 该项目的主要成果之一将是确定公民科学家所作地下水和地表水水位测量的可靠性和有效性，同时沿着查明与他们在这方面的测量有关的其他问题。 公民科学家收集的数据将被研究人员用于开发和评估将地下水位和降水数据与暴雨洪水联系起来的模型。这些模型将有助于水专业人员/工程师通过提供基于降水量和地下水位深度的预期洪水信息，维持受暴雨洪水影响的环境系统。

CBET 1644650 (Etheridge)This award is under NSF's topic of Public Participation in Scientific Research. The investigators will assess the reliability, validity and trustworthiness of data collected by citizen scientists by investigating the drivers of flooding following storm events on Bogue Banks, a barrier island in North Carolina. Forty citizen scientists will be recruited for the the project to (a) document areas prone to storm water flooding, and (b) measure and record groundwater and surface water levels in coastal communities over a three month period. The citizen science team will deploy 20 automated water loggers in wells to collect independent groundwater data with which to compare data collected by citizen scientists. The citizen scientists will also be asked to identify areas prone to stormwater flooding where staff gages will be installed by the investigators to measure surface water ponding during storm events. The citizen scientists will be tasked with recording the water level and taking photos of the staff gages in flooded areas using smart phones or other devices. The investigators will then use image processing/machine vision software to extract quantitative data from the photos for comparison with the data recorded by the citizen scientists. A groundwater model will be used to simulate the impact of water table fluctuations on stormwater flooding events. One of the major outcomes of this project will be a determination of the reliability and validity of the groundwater and surface water level measurements made by citizen scientists along with the identification of other issues associated with their measurements in this context. The data collected by the citizen scientists will be used by the researchers to develop and evaluate models that relate groundwater level and precipitation data to stormwater flooding. Such models would be useful to water professionals/engineers in sustaining environmental systems impacted by stormwater flooding through the provision of information on anticipated flooding that is based on precipitation and depth to the water table.
