Investigation Of Present Thermal Regime Of Missouri River In Missouri, James C. Maxwell Dec 1972

Investigation Of Present Thermal Regime Of Missouri River In Missouri, James C. Maxwell

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

The applicability of power spectral density techniques, Fourier series analysis, and linear regression to the mathematical modeling of river water temperature is demonstrated. Consideration is also given to the problem of estimating thermal inputs to rivers from man-made sources such as electrical power plants. First, power spectral density techniques are used in the time-series analysis of water temperature records which were taken from the Missouri River. Two spectral ranges are then studied from the standpoint of their applicability to (1) mathematical model building and (2) detection and identification of cyclic thermal inputs. Next, a Fourier regression fit to the time-series …


Epeirogenic And Climatic Controls Of Early Pleistocene Fluvial Sediment Dispersal In Nebraska, K. O. Stanley, William J. Wayne Dec 1972

Epeirogenic And Climatic Controls Of Early Pleistocene Fluvial Sediment Dispersal In Nebraska, K. O. Stanley, William J. Wayne

Department of Earth and Atmospheric Sciences: Faculty Publications

The change from Pliocene to Pleistocene fluvial sedimentation in Nebraska is denoted by gravel with relative enrichment of mechanically weak rock species and a two-fold increase in largest clast size. These changes in fluvial sediments suggest modification in degradational energy affecting detritus apparently related to deterioration of climate in the early Pleistocene. Cooler Pleistocene climates with increased moisture resulted in greater discharge and carrying capacity for streams headed in the Rocky Mountains and flowing across Nebraska. These streams carried granitic detritus eastward toward the continental glacier margin in easternmost Nebraska. There, streams flowing off ice sheets carrying sedimentary and metamorphic …

On November 29, 1971, the Hamilton County Ground Water Con·­servation District sponsored a meeting on groundwater management and regulation. The meeting was held at Aurora, Nebraska, and was designed for irrigators from groundwater conservation dis­tricts and county irrigation associations. Various men from state and federal agencies spoke about a variety of problems that a.re related to groundwater management. Two of the talks that were presented at the meeting are reproduced here, as is a discussion of the rules and regulations that relate to the use of groundwater in the state of Nebraska.

Effect Of The Pedernal Axis On Permian And Triassic Sedimentation, Philip F. Hock Aug 1970

Effect Of The Pedernal Axis On Permian And Triassic Sedimentation, Philip F. Hock

Earth and Planetary Sciences ETDs

The area surrounding the Pedernal Hills has been of scientific and economic interest for a number of years. The effect of the Pedernal axis on sedimentation and stratigraphy of late Paleozoic rocks is of major importance. The principal purposes of this study were to determine whether the Precambrian terrane was an active source of sediment and what effect it had on thickness of strata during Permian and Triassic time. the area was also mapped in as much detail as the scale (1:125,000) permitted.
