Lineage | Water table information from several sources were combined to produce a water-table digital elevation model (DEM) with ANUDEM software (Hutchinson, 1996). The values of the water-table DEM were subtracted from a land surface elevation DEM to produce the water table depth model. The inputs for the water-table DEM included County Well Index (CWI) water-level data from Quaternary water table (QWTA) and Quaternary buried unconfined wells (QBUA) (CWI was updated by the Minnesota Geological Survey for Part A); shallow borehole measurements by the Minnesota Geological Survey (also conducted for Part A); and elevation values of surface-water bodies, wetlands listed in the national Wetland Inventory (NWI), perennial streams, and seeps. In addition, water-table elevations were estimated from the soil classifications (Harms, 1965) where partially oxidized soils were observed indicating seasonal high water-table conditions. (A digitized version of this soil survey, dated 1/26/2003, was provided by Wabasha County.) The ANUDEM algorithm uses a locally adaptive criterion that minimizes the profile curvature. By using this technique, ANUDEM retains realistic hydrologic drainage. |
