Measurements Of Electron Density Structure In Striated Barium Clouds, K. D. Baker, J. C. Ulwick

Space Dynamics Laboratory Publications

Results are presented of the first measurements of detailed structure of electron density within striated vapor releases in the ionospheric F-region. Six rocket probes penetrated ion clouds in three separate barium release events (two in each case) and showed considerable enhancement in F-region electron density over the normal background ionization. In four traversals the electron density exceeded 10 cm- 3 with the maximum of 5 x 106cm- 3 observed in one case. Two showed dramatic structure in the electron density profiles associated with the passage through striated portions of the cloud. These structures had spatial extent as measured by the …

Feasibility Of Accelerating Construction Of The Central Utah Project, Trevor C. Hughes, L. Douglas James, Frank Haws, C. Earl Israelsen

Reports

Introduction: Objective: In April, 1977 the President's statement on water projects recommended that a number of federal water development projects, including the Conneville unit of the Central Utah Project, not be completed. The ensuing efforts of project supporters brought about a review of the projected costs, benefits, and other political, social and environmental factors and consequently, the current issue is not whether or not the project should be constructed. Rather, the objective of this report is to examine the following question: Given the fact that at least the 5 units of the CUP which have already been authorized will eventually …

Utah's 1977 Drought, Trevor C. Hughes, Clark Bigler, Jerry Olds, Richard Griffin, Arlo Richardson, L. Douglas James, Norris Stenquist, James Harvey

Reports

The Utah Drought of 1976-1977 has been characterized as the wettest drought in history. It was produced by the driest winter season of record followed by summer rains which were much wetter than normal in many regions of the state. Stream-flow is highly correlated with winter rather than summer precipitation and therefore the most severe impacts of the drought were related to the record low stream-flow during 1977 plus the ski industry impacts which were directly related to 1976-1977 snowfall. Drought impacts upon several sectors of the economy plus the extensive responses of all levels of government in the form …

Engineering Properties And Slope Stability Settlement Analysis Related To Phosphate Mine Spoil Dumps In Southeastern Idaho, Richard E. Riker, Loren R. Anderson, Roland W. Jeppson

Reports

The engineering properties of waste spoil from phosphate mines in Southeastern Idaho were determined through field and laboratory testing. Based on these properties, the slope stability and settlement characteristics of phosphate spoil dumps were determined. Hypothetical examples illustrate possible modes of foundation failures. Such failures might occur when weak foundation soils exist of when there is a lack of embankment-foundation preparation prior to the disposal of waste material. Adequate protection against slope failure occurring through the embankment material can be accomplished by grading embankment finish slopes to 2 ½ horizontal to 1 vertical or flatter and taking proper caution to …

The Reorganizational Problem Of The School Districts In Cache Valley, David P. Phippen Sr.

Undergraduate Honors Capstone Projects

Some years ago, in 1972 to be exact, I was a student senator at Sky View High School. Every once in a while we would be called together to discuss issues that affected our school. One particular session dealt with school population. Six years ago we were experiencing a lot of overcrowding in the school auditorium. The authorities at that time were concerned, and were asking our opinions, as student leaders, on the issue.

During that meeting, we learned that the school district owned land above Hyrum, and eventually a high school for the south end of the valley was …

Hydraulic Characteristics Of Pvc Pipe In Sanitary Sewers (A Report Of Field Measurements), Ronald R. Bishop

Reports

Introduction: Since pipe made of poly vinyl chloride (PVC) is relatively new, its hydraulic characteristics that cause fluid friction head loss are not as well known as those of cast iron and concrete pipe. The lack of universally accepted roughness parameters for PVC pipe is attested by the fact that most textbooks dealing with the hydraulics and the fluid mechanics do not include such values. The hydraulic characteristics of PVC pipe have been measured in the laboratory studies for both open channel flow conditions, Neale and price (1), and for full flow conditions, Jeppson (2). However, no studies are known …

Reports

Rivers draining arid basins increase in salinity content in the downstream area to the point where water users are often significantly damaged. The problem in some cases can be ameliorated by altering upstream water and land use practices. An economic trade off exists between the cost of such upstream efforts and the downstream benefits achieved. This report examines options for salinity management in the Colorado River Basin. The study sought to provide additional information to estimate 1) economic damages caused by various salt concentrations to agricultural and municipal water users and 2) economic costs of salinity control measures by upstream …
