Type 1 - Seasonally flooded basins or flats.
The soil is covered with water, or is waterlogged, during variable
seasonal periods but usually is well drained during much of the
growing season. This type is found both in upland depressions and
in overflow bottom lands. Along river courses, flooding occurs in
late fall, winter, or spring. In the uplands, basins or flats may
be filled with water during periods of heavy rain or melting snow.

Type 2 - Inland fresh meadows
The soil usually is without standing water during most of the
growing season but is waterlogged within at least a few inches of
its surface.
