The Coteau Des Prairies: An Area Study, Orville E. Gab

Electronic Theses and Dissertations

This thesis is a systematic geographical analysis of the Coteau des Prairies of eastern South Dakota. The Coteau is a flatironed-shaped plateau about 200 miles in length pointing in a northerly direction (Fig.1). The northern tip of the flatiron-shaped Coteau ends at Sargents Point, North Dakota, about 15 miles north of Marshall County, South Dakota. The heel of the flatiron or the southern edge of the Coteau des Prairies would just about follow the border between Minnehaha and Lincoln Counties of South Dakota. The eastern edge of the Coteau's extent in South Dakota parallels the Minnesota border. In Deuel County, …

City size is controversial...we present a paper that trades off the benefits and the costs of increased size. The issues are inevitably present.

Sedimentary Structures And Paleocurrents In A Flashy Channel, Kevin Bellamy

Theses and Dissertations (Comprehensive)

Highland Creek can be defined as a flashy stream on the basis of the basin and channel hydrology and hydraulics. The extremes between the low and high-flow stage are dependent on the hydro-geomorphological features of the urban environment. The peculiarities of the urban landscape, serve to differentiate Highland Creek from naturally flashy channels.

The sedimentary structures were grouped into coarse and fine facies. The deposition of material apparently occurs under progressively decreasing energy levels, during falling flow stage.

Bedform and sedimentary structure associations, and their evolution are dependent on the dynamics of the flashy channel. That is, the development of …

Hydrographic Regions Of Northern Ontario, Robert J. Thorpe

Theses and Dissertations (Comprehensive)

This paper deals with methods of classification of the drainage basins of Northern Ontario, with the identification of hydrologic regions. Discriminant analysis of the data proved to be the most valid of the options tested, although visual interpretation and grouping analysis both showed themselves to be useful. In all, four hydrologic regions were identified, and these show a strong relationship with the physical characteristics of the area. Of particular importance was the presence of glacial lacustrine clays in the Clay Belt area.

Changes In The Forest Composition In The Great Lakes St. Lawrence Forest Region Of Ontario And The Resultant Outbreaks Of The Spruce Budworm Choristoneura Fumiferana (Clem.), John F. Bowen

Theses and Dissertations (Comprehensive)

The spruce budworm Choristoneura fumiferana Clem. is the foremost forest pest in Canada. The species is endemic to eastern North America. Since the turn of the century the insect has become a major problem in the “Great Lakes St. Lawrence Forest Region” of Ontario, an area where prior to recent times the insect did not occur in damaging numbers.

Analysis of the life cycle of the insect reveals that the only limiting factor capable of controlling outbreaks is a lack of food. The required tree species is balsam fir Abies balsama (L.) Mill. The forests of Ontario have been altered …
