For the more technically inclined, a detailed description of the geological formations of the county is included near the end.

A Study On Gaseous Ebullitions Of De Gray Reservoir, Arkansas, David Pinkston

Honors Theses

This study was undertaken in order to determine the nature of and the factors that influence the gaseous ebullitions of De Gray Reservoir near Arkadelphia, Arkansas during a yearly cycle.

Two major types of gaseous ebullition are described in the literature. The first has to do with the production and ebullition of elemental oxygen from photosynthesis (Porcella et al., 1975). Hutchinson (1957) predicts that the formation of oxygen bubbles in this manner is limited to very shallow, well lighted, warm waters.

The second type of gaseous ebullition involves the anaerobic digestion of organic matter (Reeburgh, 1969). Anaerobic conditions exist in …

The History Of The Stream Preservation Movement In Arkansas, Rex Moreland Terry

Honors Theses

The core of the movement for stream preservation centers around the Buffalo River, in the Northwest Arkansas Ozarks. Because of this, the bulk of this paper will be devoted to the Buffalo.
