0095059/HelfrichThis project addresses the dynamics of buoyant coastal plumes of the sort produced by fresh-water river discharge. The main goal is to provide a quantitative description of buoyant coastal currents over a sloping bottom. The structure of such currents will be explored with a combination of analysis of existing observational data, laboratory experiments and numerical modeling. Existing theoretical estimates of the width of the current, the depth of the offshore edge, and the speed of advance of the nose of the current will be tested. The observational data are from an experiment in the Chesapeake Plume. The laboratory data will come from experiments in a rotating tank. The numerical model is a version of the Princeton Ocean Model (ECOM3d).

0095059/Helfrich该项目研究了由淡水河流排放产生的那种漂浮的沿海羽流的动态。 主要目标是提供对倾斜底部的沿海浮力流的定量描述。 将结合现有观测数据、实验室实验和数值模型的分析来探索这种电流的结构。 现有对海流宽度、近海边缘深度以及海流前端前进速度的理论估计将受到检验。 观测数据来自切萨皮克羽流的一项实验。 实验室数据将来自旋转罐中的实验。 该数值模型是普林斯顿海洋模型 (ECOM3d) 的一个版本。
