Soil and landscape effects on water table depth in three Indiana soils

McClelland, James H. January 1994 (has links)
Depth to water table in soils influences soil properties such as color and horizon thickness and, in some cases, determines soil classification under Soil Taxonomy. The objective of this study was to determine the depth to water table in three Indiana soil series and to evaluate the effect of soil series and landscape on water table levels. The three soils studied were moderately well drained Glynwood, somewhat poorly drained Blount, and poorly drained Pewamo soil series. The effect of soil horizon on water table levels was also examined.Data were collected from 3/21/94 to 6/6/94 at the Hults Environmental Learning Center in Albany, Indiana. The effect of soil type on water table levels was observed as measurable differences in drainage characteristics in the three soil series. Soil horizon had limited effect on water table fluctuations. Water percolated easily through all A horizons. Water temorarily perched upon the B horizon in the Glynwood soils. Landscape position appeared to play a limited role in water table fluctuations. / Department of Natural Resources and Environmental Management

Water table fluctuation in an East Central Indiana toposequence

Smith, Jill M. January 1996 (has links)
Groundwater affects the development of soil in many ways. Due to the natural relationship between soil and groundwater this study was aimed at determining whether soils affect the water table depth, episaturation occurs, and hydric soils exist at the study site. The three soils studied include Pewamo (poorly drained), Blount (somewhat poorly drained) and Glynwood (moderately well drained).Water table data were collected in 1994 and 1995 at the Hults Environmental Learning Center in Albany, Indiana. Soil, by itself, was not found to be significant in affecting water table depth whereas position (horizon), soil by position and Julian date were all found to be highly significant. Soils were affected by existing drainage tile found in Pewamo that acted to lower the water table. Blount and Glynwood were found to have a period of episaturation whereas Pewamo was found to be endosaturated. The soils were not found to be hydric based on the depth to the water table only. / Department of Natural Resources and Environmental Management
