Figure 48. Isopach map showing overall changes in bottom configuration between 1967 and 1990 

 at East Pass, Florida. Red contours (2-ft interval) represent erosion, while green (1 -ft 

 interval) represent deposition. The migration of the channel thalweg to the east is 

 obvious, as is the growth of scour holes at the jetties. Map computed by subtracting 

 June 1967 surface from February 1990 surface. (Original bathymetric data courtesy of 

 Mobile District)
