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

本课题探讨了海面流雷达（OSCR）系统在出水口混流区识别中的应用。一个OSCR系统的单次部署通常相当于部署超过1000个电流表，电流表之间的间隔大约为几百米。显然，OSCR系统有能力在更大的空间和时间细节上定义环境表面电流，比目前使用任何其他测量方法都可行。本研究将调查短期OSCR部署的数据是否可以有效地纳入（远场）混合模型，该模型描述了污水排放口排放的污染物的分散。该项目包括三个任务：(1)验证短期（以一个月为单位）OSCR部署测量的空间电流模式的平稳性；(2)开发一种算法，利用OSCR测量来模拟海洋排水口排放的污染物混合；(3)利用开发的算法在可获得OSCR测量的站点预测色散，并通过比较预测的稀释度和测量的稀释度来验证算法。＊＊＊

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. ***
