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.

本计画将结合联合收割机与数值模拟，以探讨与海角相关浅滩之泥沙输移问题。 作者将测试的假设，潮汐驱动的流动起着重要的作用，在这个波为主的设置，并导致一个显着的近海运输的沉积物。 现场测量将包括声学多普勒海流剖面仪和系泊海流计，以在北卡罗来纳州的Cape Lookout Shoal建立潮汐和高频流。 荧光和沙子示踪剂和光学后向散射将用于评估沉积物的运输，温度/盐度测量将确定河口沃茨的作用。 这项研究的结果是相关的广泛的社会问题，包括海岸侵蚀和污染物运输。
