# # # Surface waters in this stretch of the coast are also affected by several forcing functions (Wolfe 1990) not exerted on inland waters. Winds play a major role in setting up circulation on the shallow coast, resulting in a net long-term movement of coastal waters north and west during late spring, summer and early fall. In contrast during the winter months a net circulation to the south and east results from the winds associated with passage of cold fronts. Short-term convective on-shore /off-shore forcing functions characterize the summer months. 3.1.2 Area / Volume Distance upstream from the Gulf (as defined by the SWFWMD GIS basin boundary closure across the river) is illustrated in Figure 3-2. High resolution (typically 50 -150 meter transects) bathymetry referenced to NGVD29 was prepared, and a standard river kilometer was assigned to the mid-point of each transect. Observations were converted to mean tide level (mean tide level = NGVD + 0.59 ft) using an average of the NOAA tidal benchmarks within a 25-mile radius (Table 3-1). Mean cross-sectional areas were developed for each transect. The volume between adjacent transects was calculated and a line of organic correlation (LOC) fitted to the cumulative volume and area as a function of river kilometer (Figure 3-3). Correlations were limited to river kilometers less than 5 to improve the fit, and because there is only one bottom salinity observation available above Rkm 4.6 (See Figure 4-6) Figure 3-2 Location of bathymetric survey transects. # # # # # # # # # # # # ## # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # ## # # # # # # # # # # # # # # # # # # ## # # # # # # # # # # # # # # # # # ## # ## # # # # # # # # # ## # # # # # # # ____________________________________________________________________________________________ Proposed Minimum Flows and Levels for Weeki Wachee River Page 40 of 164 Estuary Characteristics
