6. Variation of estuarine circulation in the PRE

In order to identify the variation of the longitudinal circulation in the spring and neap tide cycle in the PRE, the wind forcing is withdrawn in a modeling run of the FVCOM in the PRE, and modeling results without wind forcing are generated. To remove tidal oscillations, a 25-hour low-pass filter is applied to the modeling outputs of the velocity, salinity, and eddy viscosity. An along-estuary and cross-estuary sections are selected to display modeling results, as shown in Figure 14.
