Description:
Water isotopy is introduced as a best management practice for the prediction of sustained ground water inflows to prospective constructed wetlands. A primer and application of the stable isotopes, 18O and 2H, are discussed for riparian wetland restoration areas among an agricultural landscape in southwestern Ohio. Conventional piezometric water data are compared to the evaporative potential represented by �18O values across a transect which includes numerous tile drains. All successful constructed wetland areas thus far at Shaker Trace are represented by ground water with depleted �18O values below -9.0 o/oo VSMOW. Such areas of sustainable ground water inflow could either be due to perched units at depth or simply the result of an increased flow gradient.
