3. FIGURE 2.3 Examples of coastal plain estuaries: Winyah Bay and North Inlet, South Carolina. Winyah Bay is a classical coastal plain estuary, whereas the North Inlet system is a coastal plain salt marsh estuary.

4. FIGURE 2.4 Cross-sectional profiles of an arbitrary coastal plain estuary, showing the same section in 50 times vertical exaggeration (top) and without any vertical exaggeration (bottom). Coastal plain estuaries have very wide and shallow cross sections. When these sections are presented with vertical exaggeration (which is most often the case), this gives a misleading impression.

10. FIGURE Changes in stratification brought about by tidal straining. Before onset of ebb tide, stratification is often negligible (upper left). Owing to vertical shear in the tidal current, near-surface waters are advected further seaward than near bottom waters, which increases stratification. The water column then destratifies by the end of the flood tide (lower right).

11. FIGURE (a) Remote effect resulting from Ekman transport of shelf waters into an estuary in the northern hemisphere driven by westward winds. Water levels increase throughout the estuary. (b) Local effect resulting from winds blowing landward over the estuary surface. Water levels increase in the landward reaches of the estuary, and currents flow upwind near the surface, and downwind near the bottom.
