Figure 21. Numerical grids used for tidal and storm surge computations 



in this study are shown. The storm surge ("offshore model") grid covers a 

 very large area since it is necessary that the winds that produce the surge be 

 modeled. Wind fields associated with storms can cover very large areas. The 

 tidal grid ( "nearshore model") covers a smaller area than the storm surge grid 

 but a larger area than the shore processes grid. The tidal grid must cover a 

 moderately large area in order to include all of the inlets that connect the 

 sound areas with the ocean.

 Figure 21 were used to provide boundary conditions for tidal and storm surge
