unstable features that can migrate along the coast or open and close in a 

 short period of time. Tidal flow into and out of the inlets usually forms 

 shoal deposits from material transported by strong tidal currents (Figure 2) . 

 Such shoals formed seaward of the inlet are called ebb tidal shoals and may or 

 may not be present because in many cases the material transported seaward may 

 be dispersed by waves and currents. Shoals formed landward of the inlet are 

 called flood tidal shoals and are usually present in the more protected back- 

 barrier environment.
