Estimating the ground-water contribution in wetlands using modeling and digital terrain analysis

Abstract: Wetland classification and management often requires information on the contribution of ground water to a wetland's water budget. Direct estimation of this parameter, however, is time-consuming, expensive, and can typically only be accomplished for small areas. Thus, a method to characterize ground-water flow in wetland areas and regions may be useful in many applications. The estimation technique described combines the use of a digital elevation model (DEM) with transient numerical modeling and assumes that t… Show more

“…Riparian buffers that seem well positioned according to surface topography can be ineffective when subsurface flow goes around the buffer or deep beneath the biologically active soils of the buffer zone (Denver 1991, Altman and Parizek 1995, Speiran 2010. Methods for quantifying key constraints on subsurface flow (e.g., Gerla 1999, Baker et al 2003, Kellogg et al 2008) could be incorporated to improve model results. Even without such improvements, we did observe strong and statistically significant buffer effects in the Coastal Plain and Piedmont study watersheds, which confirms that our simplifying assumptions are useful.…”

“…In Michigan, surface topography is the most important factor driving patterns of regional groundwater flow (Hoaglund and others 2002). Elsewhere, research suggests that surface topography can be an important predictor of groundwater flux (Gerhart 1984, Hinton and others 1993, Dawes and Short 1994, Gerla 1999). Thus, this assumption is not at all uncommon in conceptualizations of water table dynamics, although it is clear that it does not hold equally well in all climates or in all stratigraphies (Heath 1987, Winter and others 1998, Winter 2001.…”

“…The Shingobee watershed has been the topic of several prior modeling studies (Karls, 1982;Locke, 1995;Gerla, 1999). For this study, a one-dimensional evapotranspiration/unsaturated flow/heat transfer model for the vadose zone was constructed to calculate temporal variations in recharge to the aquifer.…”
