Abstract: Under the auspices of the National Flood Insurance Program (NFIP), a numerical study was undertaken to determine the sensitivity of predicted storm tide levels within an estuary to hurricane storm characteristics (intensity, track, etc. ) and specification of man-made and natural features. The primary objective was to attach 'levels of significance' to the modeling components. The numerical model uses a standard grid configuration and can accommodate subgrid-scale features such as channels and barriers. Several cases were run varying the characteristics of the hurricanes and the physical make-up of the 'test basin. ' An assessment was made of the importance of these elements in contributing to the localized 100-year storm surge elevation.
