Crops are planted so growth, development and harvest correspond closely to the season most favorable for yield and quality. With exception of fall-seeded small grains and some forages, most Nebraska crops are planted in the spring when temperature and precipitation are increasing.


Problems Of Pollution: Benefits, Risks And Regulations, Richard E. Pogue, Dean E. Abrahamson Jan 1968

Problems Of Pollution: Benefits, Risks And Regulations, Richard E. Pogue, Dean E. Abrahamson

Journal of the Minnesota Academy of Science

The growing concern of the scientific community and informed segments of the public about the proliferation of untested nuclear power plants demands further evaluation of their environmental impact before irrevocable decisions are mode. This paper considers the problem of low-level radioactive wastes controllable at the source. A brief background is given of the governmental agencies concerned with radiation monitoring and protection. The underlying philosophy behind radiation protection and the guidelines for putting this philosophy into practice are considered. The risk implicit in these guidelines is assessed in terms of the expected increased incidence of specific injuries to human populations.


Biological Aspects Of Heat Pollution, Theodore Olson Jan 1968

Biological Aspects Of Heat Pollution, Theodore Olson

Journal of the Minnesota Academy of Science

The importance of temperature as an environmental factor has long been recognized by the ecologist, and its special impact upon the aquatic ecosystem has been of interest to aquatic biologists since they first began to observe interactions between living things and the physical environment. Interest in water temperatures as an environmental factor has recently become more widespread; and one aspect of the phenomenon, namely "thermal pollution," has attracted special attention.


Discharge Of Radioactive And Thermal Wastes, Richard E. Pogue, Dean E. Abrahamson Jan 1968

Discharge Of Radioactive And Thermal Wastes, Richard E. Pogue, Dean E. Abrahamson

Journal of the Minnesota Academy of Science

A combination of several economic factors, together with growing concern about air pollution associated with conventional, fossil-fuel electric generating facilities, hos contributed to the increase in size and number of nuclear-powered plants. Although these nuclear plants are "clean" from the standpoint of conventional air pollutants, they must dispose of thermal and radioactive wastes. This paper outlines the sources and quantities of these wastes, based on technical data for the boiling-water reactor proposed for Monticello, Minnesota.

Planning Flood Control Measures By Digital Computer, James Norris Cline, L. Douglas James

KWRRI Research Reports

The purpose of this study was to develop adequate guidelines whereby those interested in flood control planning would be able to apply a pair of digital computer programs known as the University of Kentucky Flood Control Planning Programs to ease the computational burden of evaluating specific flood control situations. Program II determines the economically optimum combination of channel improvement, land use restriction, and flood proofing for flood damage abatement. Program III also incorporates reservoir storage into the planning process. The Programs are not intended to provide a finished design but rather to select the optimum combination of flood control measures …


The Fish Population Of Lake Poinsett, South Dakota, As Indicated By The Catch, James C. Congdon Jan 1968

The Fish Population Of Lake Poinsett, South Dakota, As Indicated By The Catch, James C. Congdon

Electronic Theses and Dissertations

Gill nets, trap nets, an otter trawl, and a boom-type electric shocker were utilized to obtain samples of the fish population of Lake Poinsett, South Dakota. The species and size composition of the samples differed significantly with time of season, time of day, location on the lake, and type of gear. Decreased activity following spawning was the apparent cause of a midsummer decline in gill net and trap net catches of black bullhead, black crappie, and white crappie. A late summer increase in the catch of yearling black bullheads, crappies, white bass, carp and bigmouth buffalo was attributed to an …


Limnology Of Selected South Dakota Lakes, Artwin E. Schmidt Jan 1968

Limnology Of Selected South Dakota Lakes, Artwin E. Schmidt

Electronic Theses and Dissertations

Physical, chemical, and biological aspects of 45 lakes in South Dakota were studied from July 1965 to July 1967. Maximum water temperature at the surface reached 28 C. Most of the lakes studied exhibited continuous circulation except when ice covered. Thermocline formation was observed in six of the lakes. Light transmission was influenced by turbidity, and varied greatly within individual lakes and among lakes. Dissolved oxygen concentrations ranged from near saturation to less than the recommended minimum for fish life. All likes studied were basic ranging from a pH of 7.1 to 11.3. Specific conductance of lakes occupying open basins …


Evaluation Of The Legal Institutions Of Diversion, Transfer, Storage, And Distribution Of Water In Kentucky, A. Dan Tarlock Jan 1968

Evaluation Of The Legal Institutions Of Diversion, Transfer, Storage, And Distribution Of Water In Kentucky, A. Dan Tarlock

KWRRI Research Reports

In 1966 Kentucky enacted a water use regulation statute which makes :important modifications in the common law doctrine of riparian rights by authorizing the state to grant permits for the use of water. The permit system is primarily designed to allow the state to gather the information necessary to conduct long range planning studies. However, the permit system can also be used to apportion water among competing users. The report examined the common law of riparian rights to determine how KRS Ch. 151 had modified it and analyzed some of the legal problems which could arise in the administration of …


Evaluation Of Runoff Coefficients From Small Natural Drainage Areas, Carlos Fix Miller, L. Douglas James Jan 1968

Evaluation Of Runoff Coefficients From Small Natural Drainage Areas, Carlos Fix Miller, L. Douglas James

KWRRI Research Reports

The Kentucky Department of Highways, as do most other agencies which build small drainage structures, estimates flood peaks as the product of a runoff coefficient, a rainfall intensity, and the drainage area, Available procedures were applied to 39 gaged watersheds in and near Kentucky and compared with the results of frequency analysis of historical stream gage records. The methods consistently underestimated the flood peak.

Therefore, a more intensive study (using the Stanford Watershed Model) of the runoff coefficient was undertaken by dividing it into overland flow and streamflow components. A set of curves was developed based on the 50-year event …


The Effects Of Geographical And Climatic Setting On The Economic Advantages Of Alternative Flood Control Measures, Clyde R. Dempsey, L. Douglas James Jan 1968

The Effects Of Geographical And Climatic Setting On The Economic Advantages Of Alternative Flood Control Measures, Clyde R. Dempsey, L. Douglas James

KWRRI Research Reports

It has long been realized that tributary urban development and channel improvement greatly affect the flow regime in a given watershed. A previous study used the Stanford Watershed Model to derive relationships expressing how the flood peaks in Sacramento, California, might be expected to vary with changing conditions of urbanization, channelization, and tributary drainage area. In order to observe the effects of climatic setting and geographical location on these relationships, the same type of analysis was applied to a drainage area near Louisville, Kentucky.

If reservoir storage is to be considered in a flood control program, it is necessary to …

Urban Geology—A Need And A Challenge, William J. Wayne Jan 1968

Urban Geology—A Need And A Challenge, William J. Wayne

Department of Earth and Atmospheric Sciences: Faculty Publications

Urban land uses are rapidly converting open land into intensively used land. Generally, in planning those uses, a comprehensive study has included everything except an evaluation of the land in three dimensions. Geologists are eminently well equipped to supply the missing data, but they must also be aware of the needs of the urban community and the kinds of information needed by planners if they are to write reports usable by planners. Urban and environmental geology is a newly expanding field in the use of geologic data to help solve some urban problems in the planning stage. It is likely …

Feasibility Of Rating Current Meters In A Velocity Field, Gaylord V. Skogerboe, Lloyd H. Austin, Roland W. Jeppson, Chi-Yuan Wei Jan 1968

Feasibility Of Rating Current Meters In A Velocity Field, Gaylord V. Skogerboe, Lloyd H. Austin, Roland W. Jeppson, Chi-Yuan Wei

Reports

Preliminary studies employed an 8-inch (outlet diameter) contracting cone and an 8-inch converging nozzle. The design of the cone is based on an electromagnetic analogy reported by Smith and Wang, while the nozzle was designed assuming potential flow and using numerical methods to obtain the solution. Both designs yielded fairly uniform velocity fields, any deviations being primarily due to either construction or measurement techniques. The towing tank rating for a Pygmy current meter was compared with the submerged jet rating, the difference being 1 or 2 percent. A Prototype system was constructed using a 16-inch contracting cone (d). Two Type …

Atomic Absorption As An Index Of The Silver Concentration In Precipitation, Silver Iodide Plume Studies, Part 1, Joel E. Fletcher, H C. Millar Jan 1968

Atomic Absorption As An Index Of The Silver Concentration In Precipitation, Silver Iodide Plume Studies, Part 1, Joel E. Fletcher, H C. Millar

Reports

The Perkin Elmbver Model 303, equipped with the DCR-1, digital concentration readout, was evaluated as to its ability to provide an index of silver concentration in water solutions, without concentrating in any manner. The procedures, principal settings, and adjustments which must be observed are described.

This instrument can detect the difference between concentrations of 10-15 and 10-12 gm/ml. However, as the concentration of silver decreases the experimental error increases to a point at which the error becomes greater than the differences in readout due to differences in silver concentration.
