Mobility And Behavior Of Raccoons In Eastern South Dakota, George L. Geis

Electronic Theses and Dissertations

Introduction: Increasing populations of raccoons (Procyon lotor) and reports of depredation on upland game, poultry, and garden crops indicated a need for research concerning behavior, mobility, and range of raccoons. The raccoon has seemingly adapted to the dry environment of the northern agricultural plains. According to records, the original range apparently did not extend into South Dakota. Lewis and Clark did not report raccoons when they traveled along the Missouri River in 1804 and 1806 (Coues, 1893). Although Visher (1918) noted that raccoons were not rare in wooded areas along streams in western South Dakota, he made no mention of …

Measuring Water With Parshall Flumes, Gaylord V. Skogerboe, M. Leon Hyatt, Joe D. England, J. Raymond Johnson

Reports

Preface: As the value of water increases, the extent to which measurement is employed in an irrigation system also increases. Additional flow measurements provide information for improved management of the water supply. Good water management requires accurate measurement. Many devices have been developed for this purpose and are in use. Included among them are weirs, orifices, calibrated gates, Parshall flumes, and current meters. Of these, the Parshall flume is one of the most widely accepted and used. Presented in this publication is a discussion concerning the use of Parshall flumes for measuring water, including the utilization of a new approach …

Rating Flow Regulation Structures In The Bear River Canal System, Gaylord V. Skogerboe, Winford M. Barrus, Lloyd H. Austin

Reports

Introduction.

The Bear River Canal System (Fig. 1) is located below Cutler Reservoir in Box Elder County, Utah. The average annual quantity of water conveyed through the canal system is approximately 230,000 acre-feet. Any water not consumptively used in this area eventually flows in to Great Salt Lake.

Utah Power and Light Company has the rights to the waters stored in Cutler Reservoir for operating a hydroelectric plant. The irrigation distribution system below the reservoir is operated and maintained by the Utah-Idaho Sugar Company. The water is delivered to the water users through the distribution system and a nominal maintenance …

Application Of Electronic Analog Computer To Solution Of Hydrologic And River Basin Planning Problems: Utah Simulation Model Ii, J. Paul Riley, Duane G. Chadwick, Jay M. Bagley

Reports

As demands upon available water supplies increase, there is an accompanying increase in the need to assess the downstream hydrologic system. At Utah State University this problem is being approached by electronic analog simulation of the hydrologic system. Modeling concepts are based upon the development of basic relationships which describe the various hydrologic processes. Within a system, these relationships are linked by the continuity -of-mass principle which requires a hydrologic balance at all points. Once established, the model is applied to any particular geographic unit by determining the appropriate constants of the hydrologic equations. The analog computer is ideally suited …

Mathematical Hydraulics Of Surface Irrigation, Cheng-Lung Chen

Reports

The general hydrodynamic equations for a spatially varied unsteady flow in a prismatic open channel having an arbitrary cross-sectional shape can be derived from the equations of continuity and momentum. The assumptions based on the general concept of hydrodynamics and the theory of shallow water is introduced. The mathematical models in the surface irrigation can be formulated by these equations of motion with the appropriate initial and boundary conditions prescribed at the singularity point (the origin in the x, t-plane) and at x = 0. Therefore, the flow in the surface irrigation must be described by solving the boundary-value problem …

Subcritical Flow Over Various Weir Shapes, M. Leon Hyatt, Gaylord V. Skogerboe, Lloyd H. Austin

Reports

Submerged flow exists for any given structure when a change in flow depth downstream from the structure causes a change in flow depth upstream from the structure for any given constant value of discharge. The two flow depths, normally measured when submerged flow exists, consist of a depth upstream from the structure, which is used also for free flow conditions, and a depth of flow located any place downstream from the structure. The initial studies in which the submerged flow analysis was developed were made on flat-bottomed flumes (Hyatt, 1965; and Skogerboe, Walker, and Robinson, 1965). Later studies verified the …

Evaluation Of Free And Submerged Flow Data For Large Parshall Flumes, M. Leon Hyatt, Gaylord V. Skogerboe

Reports

Because the accurate measurement of water plays such an important part in water management, such structures as weirs, orifices, calibrated gates f and flumes have been developed. These structures provide the means for reasonable measurement of the smaller flows (1: .. 100 cfs), but for the large flows (100-3,000 cfs) the current meter, large Parshall flume, and various other flumes are commonly used. Where a permanent structure is required, the most widely accepted and utilized method for measurement of large flows is probably the Parshall flume. The purpose of this report has been to collect the existing flow data for …

Population Distribution And Mobility Of Deer In Eastern South Dakota, Rollin De Mers Sparrowe

Electronic Theses and Dissertations

Population distribution and mobility of deer were studied intensively along a 15-mile stretch of the Big Sioux River, and less intensively on an expanse of 1400 square miles in central eastern South Dakota. Objectives were to determine relative population numbers and distribution of deer, the extent of their daily and seasonal movements, and the principal factors influencing these populations and movements, and to test winter hard counts as a population index. Deer were captured in Clover traps or with a Cap-Chur gun and were marked individually with ear tags, ear streamers, and collars. Some deer were tracked by radio telemetry. …

Limnology Of Three Farm Ponds In South-Central South Dakota, Larry Kim Graham

Electronic Theses and Dissertations

Physical, chemical, and biological aspects of three farm ponds in south-central South Dakota were studied from June 1964 until December 1965. Maximum water temperature at the surface reached 25.2 C, while water temperatures at the bottom of the ponds were about 2 to 4C lower than the surface. Light transmission was influenced by turbidity but generally penetrated to the bottom of the ponds except during periods of cloudy ice and snow cover. Dissolved oxygen was near saturation during periods of open water. Most chemical ions in the ponds increased annually from a winter minimum to a spring maximum. Total dissolved …

Age group II was common only in the spring and early summer. While age group III was rarely found. Average length at annulus formation was 66 mm for age group I and 84 mm for age group II. Females attained a size advantage over males …

Dieldrin Residues In Eggs And Fat Of Penned Pheasant Hens, Donald Wayne Lamb

Electronic Theses and Dissertations

At present, there is considerable interest in the effects of insecticides upon our wildlife populations. It is well known that chlorinated hydrocarbon insecticides are present in tissues and eggs of birds that receive these chemicals in their diets. Some workers, for example Gene11y and Rudd (1956) and DeWitt (1956), studied the effects of different levels of ingested insecticides on the reproduction of game birds. Additional studies are needed to relate the amount of insecticide in the diet to the level in the egg and that in turn to reproduction and effects on young birds. Work on pheasants is of special …
