A Study of the Application of Ocean Surface Current Radar Systems to the Identification of Outfall Mixing Zones

9320253中国本项目探索海洋表面流雷达系统在排污口混合区识别中的应用。单次部署OSCR系统通常相当于部署1000多个海流计，两个海流计之间的间隔约为几百米。显然，OSCR系统有能力以比目前使用任何其他测量方法可行的方式更详细的空间和时间来定义环境表面电流。这项研究将调查来自短期OSCR部署的数据是否可以有效地纳入描述从排污口排放的污染物扩散的(远场)混合模型。该项目由三个任务组成：(1)验证通过短期(大约一个月)OSCR部署测量的空间流型的平稳性；(2)开发一个算法来利用OSCR测量来模拟从海洋排放口排放的污染物的混合；以及(3)利用所开发的算法来预测OSCR测量的地点的扩散，并通过比较预测和测量的稀释来验证该算法。***

9320253 Chin This project explores the application of ocean surface current radar (OSCR) systems to the identification of outfall mixing zones. A single deployment of an OSCR system is typically equivalent to deploying over 1,000 current meters, with spacings between current meters on the order of a few hundred meters. Clearly, OSCR systems have the capability to define ambient surface currents in far greater spatial and temporal detail than is currently feasible using any other method of measurement. This study will investigate whether data derived from short-term OSCR deployments can be effectively incorporated in a (far-field) mixing model that describes the dispersion of contaminants discharged from sewage outfalls. This project is composed of three tasks: (1) Verify the stationarity of spatial current patterns measured by short-term (on the order of a month) OSCR deployments; (2) Develop an algorithm to utilize OSCR measurements to simulate mixing of contaminants discharged from ocean outfalls; and (3) Utilize the developed algorithm to predict dispersion at a site where OSCR measurements are available, and validate the algorithm by comparing the predicted and measured dilutions. ***
