Purpose: The Wolf River in western Tennessee has experienced severe channel erosion in the form of headcutting and downcutting that has extended 17 km upstream from the location at which channelization ceased in 1964. A previous study (Wiens and Roberts 2003) indicated that groundwater levels in the bottomland hardwood (BLH) wetlands adjacent to the headcut reaches may be significantly lower than in unaltered reaches. The primary goal of the study documented herein was to determine if the groundwater hydrology of BLH forests adjacent to areas of the Wolf River in which headcutting has occurred have been altered such that substantial portions of the floodplain will no longer delineate as wetlands. A secondary objective was to compare the efficacy of two less rigorous techniques for monitoring shallow groundwater with the technique of installing standard groundwater monitoring wells (Figure 1). The current study will also provide quantitative baseline data for further research and for monitoring the progress or success of any future restoration programs.
