位于西北英格兰-威尔士边境的迪河口是一项重要的资产，它支持着：欧洲最大的野生动物栖息地之一，沿着威尔士海岸线的工业重要性以及沿着英格兰海岸的住宅和娱乐用途。了解剩余高度对于确定淹没潮间带堤岸的总水位非常重要，特别是在暴风雨期间。然而，提高三维剩余循环的知识对于确定颗粒运输途径以管理水质和形态变化是重要的。利用2008年2月至3月获得的系泊数据，一个3D建模系统先前已经根据原位盐度、速度、高程和波浪观测进行了验证，以研究在完全真实强迫下河口内正斜压波的相互作用。该系统由一个循环-波-湍流耦合模型（POLCOMS-WAM-GOTM）组成。利用这个模型系统，现在评估了不同过程及其相互作用对海拔和环流每月剩余量的贡献。通过对波浪作用下潮汐控制的河口的研究，发现弱水流引起的斜压性对剩余环流的产生比波浪更重要，即使在河口处也是如此。月剩余环流以潮汐和斜压过程为主，剩余河口地表高程主要受季节外强迫的影响，局地风条件次之。在风暴条件下，三维辐射应力在事件尺度上对高程和环流都很重要，但在月时间尺度上影响很小。
The Dee Estuary, at the NW English–Welsh border, is a major asset, supporting: one of the largest wildlife habitats in Europe, industrial importance along the Welsh coastline and residential and recreational usage along the English coast. Understanding of the residual elevation is important to determine the total water levels that inundate intertidal banks, especially during storms. Whereas, improved knowledge of the 3D residual circulation is important in determining particle transport pathways to manage water quality and morphological change. Using mooring data obtained in February–March 2008, a 3D modelling system has been previously validated against in situ salinity, velocity, elevation and wave observations, to investigate the barotropic–baroclinic wave interaction within this estuary under full realistic forcing. The system consists of a coupled circulation-wave-turbulence model (POLCOMS-WAM-GOTM). Using this modelling system the contribution of different processes and their interactions to the monthly residuals in both elevation and circulation is now assessed. By studying a tidally dominated estuary under wave influence, it is found that baroclinicity induced by a weak river flow has greater importance in generating a residual circulation than the waves, even at the estuary mouth. Although the monthly residual circulation is dominated by tidal and baroclinic processes, the residual estuarine surface elevation is primarily influenced by the seasonal external forcing to the region, with secondary influence from the local wind conditions. During storm conditions, 3D radiation stress becomes important for both elevation and circulation at the event scale but is found here to have little impact over monthly time scales.
