ABSTRACT
Frequently ˆooded soils are semi-terrestrial and/or semi-aquatic soils with aquic or epiaquic moisture regimes. They are inˆuenced by various aquatic sources, including groundwater, static water, return seepage, and ˆood water. In general, large variations in ˆooding frequency as well as in ˆood water characteristics have been observed. As a result, sedimentation rates of substances also reveal a large variation according to the site-speci”c conditions.
