    you used wilbur
    so running the erode cycles on 32 bit floating point height data ( *.bt format works best )
    the underwater area will have been created ( the negative values in the data )

    the Middle earth area here around Gondor ( bay of Belfalas)
    -- the under water area only the land is black in this FALSE COLOR image


    The depest area in the above image is -16510 -- that is in the yellow area
    the green is -14000 to about -11000
    the blue -11000 to 0
    i use the negative values to gradient color the water mask

    -- now this one is ONLY near the shore



    this is one reason why i use 32 bit float image formats
