Abstract:

Includes bibliographical references (leaves 78-86) In the Herrmanns sub-catchment in the Mt. Lofty Ranges (near Mt. Torrens) soil sodicity was the dominant factor in causing clay to disperse in the eroded area along the foot slopes, wheras in non-eroded areas of the mid-slopes and on the stream banks, the dispersive power of sodicity was attenuated by the flocculative power of other soil properties.

Abstract:

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

Geology<br>M.S.<br>The city of Philadelphia is an amalgamation of extremely diverse land uses, both currently and historically, including: transportation, industrial, commercial, parks and residential areas. This urban tapestry of historical and current land use creates the potential for human exposure to heavy metals in contaminated soils. In order to evaluate this potential public health hazard, soil samples from open spaces in Philadelphia's Fairmount Park (the largest inner-city park system in the U.S.) were analyzed using a handheld x-ray fluorescence (XRF) analyzer and inductively couple

The objective of this study was to determine the correlation between potentiometric surface and the depth to selected soil morphological indicators of wetness for the Glynwood (Aquic Hapludalf), Blount (Aeric Epiaqulaf), and Pewamo (Typic Argiaguoll) soils in Delaware County, Indiana. Four years of potentiometric surface measurements were averaged and compared to detailed soil descriptions performed by the Natural Resources Conservation Service. Significant correlations exist between the morphological indicators and the potentiometric surface for the Glynwood (moderately well drained) 2-m dept

Abstract:

Rivers and streams are adversely affected by an increase in sedimentation in their waters from eroding land. High sediment loads in streams can bury fish eggs and prevent hatching, increasing nutrients in the water causing algae blooms, or even contaminating the water with heavy metals carried in or on the aggregates. The erodibility of soil is valuable knowledge to all land users so that we may predict soil loss and its potential to pollute streams. This is done by using the Revised Universal Soil Loss Equation (RUSLE). By predicting soil loss from a given landscape, land managers can take mi

Abstract:

Geology<br>M.S.<br>Paleopedology is often employed in paleoenvironmental reconstructions because the features of paleosols are affected by changes in climate, ecology, topography, and lithology over time. These changes cause small-scale variations in the morphology and apparent development of paleosols and influence the degree to which certain soil features are preserved in the rock record. When drawing inferences about paleoenvironments based on paleosols, care must be taken to ensure that as many of the soil forming factors as possible are understood. Whereas climates can be ignored over sma
