Geological and Physical Transport Processes on a Cape Attached Shoal: Field Observations and Numerical Modeling

该项目将结合现场测量和数值模拟来解决与海角相关的浅滩沉积物运输问题。作者将验证潮汐驱动流在这种波浪主导的环境中起重要作用的假设，并导致重要的离岸沉积物运输。现场测量将包括声学多普勒电流剖面仪和系泊电流计，以建立北卡罗来纳州海角了望浅滩的潮汐和高频流量。荧光示踪剂和沙示踪剂以及光学后向散射将用于评估沉积物的迁移，温度/盐度测量将确定河口水的作用。数值模拟将把潮汐和风力驱动的水流与泥沙运输模式结合起来。这项研究的结果与广泛的社会问题有关，包括海岸侵蚀和污染物运输。

This project will combine field measurements and numerical modeling to address the issue of sediment trasport on shoals associates with a cape. The authors will test the hypothesis that tidally-driven flow plays an important role in this wave-dominated setting, and results in a significant offshore transport of sediments. Field measurements will include acoustic doppler current profiler and moored current meters to estabish tidal and higher-frquency flows at Cape Lookout Shoal, NC. Fluorescent and sand tracers and optical backscatter will be used to assess sediment transport, and temperature/salinity measurements will determine the role of estuarine waters.s Numerical modeling will integrate tidal and wind-driven flows with sediment transport patterns. Results of this study are relevant for a wide range of societal issues including coastal erosion and pollutant transport.
