Application of Magnetic Susceptibility for Wetlands Delineation

Wetlands are a natural resource that are protected under federal regulations, therefore the<br>delineation of wetlands is necessary to ensure their protection. A study using magnetic susceptibility<br>was undertaken in central Mississippi to identify the transitional zone between non-hydric (uplands) and<br>hydric (wetlands) soils. The soils were clayey with a minor percentage of sand. A survey line that<br>traversed an upland, transitional zone, and wetland on each end of a transect was revisited four times<br>during a single year.
