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.

这项研究将继续建模耦合河口架子底部频率循环的研究，包括密度和风驱动。 提出了五个特定的目标：1。与先前工作期间开发的羽流模型的批判性评估，与在MECCAS计划中获得的Chesapeake Plume的观察相比； 2。开发简化版本的河口羽流模型，该模型可用于模拟与均匀的长岸电流如何假设相比，具有更复杂动力学的环境架子中的羽流。 3。改善现有的稳态羽流模型，包括插座，质量夹带和浮力损失的影响，通过垂直混合在羽流下； 4。开发主要河口海上密度和风驱动架子循环的诊断模型；以及5。第二架河口羽流模型的内书架循环描述的使用，以提供内部大陆架上河口羽状动力学的描述，以包括密度和风驱动零件的所有主要物理机制。
