Wetland hydrology

Primary indicators

inundation | saturation within 12 inches of surface | water marks | drift lines
sediment deposits | drainage pattern

 
Drift lines
Drift lines are deposits of debris that run parallel to the direction of water flow. Debris can be made up of sediment, leaves, stems, branches or litter. This indicator is most likely to be found near streams or other wetlands water sources.
