MICRODEM Sample Output

 

Water level in downtown Annapolis and the Naval Academy from a storm such as Hurricane Isabel, overlaid on a 1m resolution LIDAR DEM.

Water levels go from 0.2 m to 2.5 m in 0.1 m steps. This requires that the point be below the water level, and that it have a clear path to the bay.  This will be fooled if water can come through the seawall, for instance, but provides a best estimate.

There are many caveats to this analysis, and there is no claim that it accurately portrays what happened in Isabel or would happen in a future storm.

This is a low resolution depiction for web delivery, and does not do justice to the quality of the DEM data.

Actual water levels for recent hurricanes were probably:

  • Ernesto, September 2006, 0.9 m
  • Isabel, September 2003, 2.0 m
  • Fran, September 1996, 1.2 m

All water levels referenced to NAVD.
