This study will continue modeling studies of coupled estuary-shelf subtidal frequency circulation, both density-and wind driven. Five particular objectives are posed: 1. A critical evaluation of plume models developed during previous work in comparison with observations of the Chesapeake plume obtained during the MECCAS program; 2. development of a simplified version of the estuary plume model that can be used to model plumes in ambient, inner shelf waters that have more complicated dynamics than the uniform longshore current how assumed; 3. Improvement of the existing steady-state plume model to include the effects of interfacial friction, mass entrainment, and buoyancy loss by vertical mixing beneath the plume; 4. Development of diagnostic models of density- and wind driven shelf circulation offshore of a major estuary; and, 5. Use of the results of the fourth for the inner shelf circulation description of estuary plume model of the second to provide a description of estuary plume dynamics on the inner continental shelf to include all major physical mechanisms for both the density and the wind-driven parts.

本研究将继续进行耦合模型研究， 河口-陆架潮下带频率环流，密度和 风力驱动 提出了五个具体目标：1。一 对以前开发的羽流模型进行严格评估 与观测到的切萨皮克烟羽进行比较 在MECCAS计划中获得; 2.发展 简化版本的河口羽流模型，可用于 模拟环境中的羽状流，内陆架沃茨， 复杂的动力学比均匀的沿岸流 假设; 3.现有稳态羽流的改进 模型包括界面摩擦、质量 夹带，和浮力损失的垂直混合下， 羽流; 4.发展密度和风的诊断模式 主要河口近海的驱动陆架环流; 5. 利用第四个结果进行内货架 河口羽流模式的环流描述 提供了一个描述河口羽动力学的内部 大陆架的所有主要物理机制， 密度和风力驱动的部分。
