This analysis uses a Lidar Digital Elevation model, and the MICRODEM computer program to produce a KML file you can view in Google Earth.  You can see the predicted flooding at a number of water levels, referenced to NAVD of 1988.  We also have historic shorelines depicted by the Maryland Geological Survey; perhaps not surprisingly, almost all the area that floods is fill emplaced after the founding the Naval Academy in 1845.

You can see the current tides and refer them to both NAVD and MLLW, as well as several other vertical datums, in either feet or meters.

You can compare the observations with the NOAA prediction.  Insure that you understand the tidal datum used in the model, the units (feet or meters), and then determine the matching  NAVD1988 level.

• https://tidesandcurrents.noaa.gov/ofs/ofs_station.shtml?stname=Annapolis&ofs=cb&stnid=8575512&subdomain=0 .  This will be in MLLW, and has predictions that do not match the other two sites.

• https://water.weather.gov/ahps2/hydrograph.php?wfo=lwx&gage=apam2  The vertical datum is MLLW, which is hidden at the very bottom of the page, and you cannot change.
