A Survey Of Missouri's Water Resources Involvement, Frank R. Ellis Ii

Masters Theses

"A survey of the procedures for development of water resources in the State of Missouri reveals shortcomings in many areas. Recommended improvements include: 1) revising and publishing a statewide water plan, 2) improving methods of project evaluation and priority establishment, 3) expanding methods of citizen involvement, and 4) reorganization of state agencies and legal authority. The paper examines the history of water resource involvement by the State of Missouri, and current jurisdiction of state agencies, including procedures for review of environmental impact statements"--Abstract, page iv.

Solving Three-Dimensional Potential Flow Problems By Means Of An Inverse Formulation And Finite Differences, Allen L. Davis, Roland W. Jeppson

Reports

A finite difference method is developed to solve the three-dimensional, steady, incompressible, potential flow equations obtained by using a potential function, o, and two mutually orthogonal stream functions, u and u*, to describe the flow. Problems are formulated in an inverse space where the potential function and the two stream functions are the independent variables, and the Cartesian coordinates x, y, and z are the dependent variables. The boundaries of the problem in the physical space, including the free surface, have known positions in the inverse space, so trial and error adjustments to the positions of the boundaries are unnecessary. …

Integrated Measurement Of Soil Moisture By Use Of Radio Waves, Duane G. Chadwick

Reports

An integrated value of soil moisture can be determine dby measuring the attenuation of vertically-polarized surface radio waves taht are propagated over the ground between a transmitting and receiving atenna. Soil moisture values in the root-zone region were measured over longitudinal distances typically ranging from 50 feet to 600 feet with good results. Integrated soil moisture measurements over greater distances are also possible. Received field strength of propaged radio surface waves closely matches theoretical calculations. The measurement is easily made and does not disturb the soil. Dense, green vegetation, such as alfalfa or corn, causes errors in measurement accuracy. Less …

A Comparison Of Three Urban Hydrology Models, Richard F. Astrack

Masters Theses

"Three models, the British Road Research Laboratory Hydrograph Method, the Hydrocomp Simulation Program, and the HEC-1 Flood Hydrograph Package, are applied to the Boneyard Creek basin. Comparing the ability of these models to reproduce the observed peak discharge, time of the peak, and the first runoff volume determines the accuracy of these models"--Abstract, page iii.

A Highway Rest Area Design Based On A Use Study In Outstate Missouri, Dimitris Peter Perandakos

Masters Theses

"The limited number of rest areas in the State of Missouri does create a major problem for the motorist travelling in this state.

The author became more aware of this problem from personal experience and decided to investigate it. For that he interviewed over one thousand motorists on the only rest area that is located on 1-44, near the city of Stanton. He also took traffic counts to determine the average daily traffic volumes of Highway 1-44 and of the rest area stated above.

The data collected from the above steps was used for the design of a new rest …

A Study Of The Ability Of Water Treatment To Remove Trace Organics, Daniel Lee Oliver

Masters Theses

"The purpose of this investigation was to study the ability of water treatment processes, especially coagulation and chlorination, to remove trace organic materials from raw river water. Trace organic concentrations were determined using the Organics-Carbon Adsorbable (O-CA) technique, a miniaturized Carbon Adsorption Method (CAM).

Missouri River raw and treated water, obtained on 3 different dates at the Jefferson City, MO, water treatment plant, was used. The effect of various treatment steps, including settling, softening with lime, coagulating with copperas or alum over a range of doses, and chlorinating at the dose necessary to give a free residual of 2 mg/1 …

Driver-Vehicle-Roadway Interaction Model, Mark E. Jaeger

Masters Theses

"A non-trivial simulation model has been developed which combines driver and vehicle dynamics with the roadway into one system. The model was successfully simulated on a portion of an existing roadway with the dynamic response and performance of the simulator being subjectively realistic. By implementing the idea of the interaction of variables, a much more detailed and representative response is obtained as compared to previous models based solely upon a single-factor-effect approach. By analyzing a simulated vehicle's velocity and trajectory, it is felt that an increase in driver "look ahead" distance or a decrease in vehicle velocity tends to improve …

The Evaluation Of An Activated Sludge Process At Elevated Temperatures, Peter J. Dawson

Masters Theses

"The feasibility of utilizing the thermal energy from an electric power plant to operate an activated sludge process at elevated temperatures (above 40°C) was assessed.

The practicality of using this heat was determined from a heat transfer analysis and the operation of the activated sludge process was evaluated from laboratory studies of a batch process treating domestic and synthetic sewage.

The tank size for a thermophilic activated sludge chamber could be reduced by 40 to 50% as compared to ambient temperatures. For thermophilic processes a temperature of 55°C is recommended because the transition phase between mesophiles and thermophiles is around …

Chemical And Ultrasonic Conditioning Of Water Treatment Plant Coagulant Sludges, Stanley Louis Klemetson

Masters Theses

"The objective of this investigation was to evaluate the use of ultrasonic energy, pH adjustment, and addition of polyelectrolytes in dewatering coagulant sludges. Emphasis was placed on the effects of the ultrasonic power output level and period of conditioning, the chemical conditioning of the sludge, and the type and origin of the sludge. Dewatering is thought to be the most practical approach for reducing the volume of coagulant sludges and efforts are being made to improve their dewatering characteristics.

An experimental system consisting of a magnetically stirred sludge reservoir, sonifier and reaction chamber, polymer feeder, and collection cylinder was developed …

Release Of Pollutants From Aquatic Sediments, Lloyd Aldon Hinkle Jr.

Masters Theses

"This study was undertaken to investigate factors governing the release of pollutants from sediments and subsequent effects on water quality. Studies were carried out to: 1) determine the characteristics of selected sediments; 2) determine the level of release of pollutants under batch and fill and draw conditions; 3) determine the effect of temperature and pH on release mechanisms; 4) determine the importance of microbial (uninhibited) release and physio-chemical (inhibited) release processes.

The sediment utilized was from the Missouri River at Jefferson City, Missouri, and the Burgher Branch near Rolla, Missouri. Five environmental conditions to evaluate the effects of pH and …

Treatment Of A Pharmaceutical Waste With The Anaerobic Filter, Norman Dale Dennis Jr.

Masters Theses

"The anaerobic filter is essentially a plug-flow, packed-bed, column type reactor in which the anaerobic bacteria responsible for the waste stabilization are attached to the filter media. This process is a relatively new concept in waste treatment which has been used only in laboratory studies. The objective of this study was to evaluate anaerobic filter performance when used to treat an actual industrial waste under controlled conditions of flow rate, organic strength and temperature.

Four 0.5 cu ft (14.25 l) laboratory filters were operated for 180 days at 35° C using a pharmaceutical waste as the substrate. By varying influent …

Attitude Scaling As A Public Involvement Tool In The Lower Mississippi River Region Comprehensive Study, William A. Lee

Masters Theses

"The planner is under considerable pressure to involve the public in water resource planning. The public, however, often lacks sufficient knowledge to offer useful comments or suggestions. The use of a Likert Type Attitude Scale in the public involvement effort of the Lower Mississippi Region Comprehensive Study demonstrates the usefulness of attitude scaling techniques in obtaining public input to the planning process. The measurement of an individual's attitude, or his thoughts, feelings and disposition to act toward some aspect of his environment with some degree of consistency, gives an indication of the goals and objectives toward which a plan acceptable …

The Linear New City -- A Pattern For New Cities Based On Efficiency Of Transportation, Public Services, And Land Use, Elbridge Wesley Bartley Iii

Masters Theses

"The linear new city is defined as a city consisting of some arrangement of relatively narrow, high-density strips, served by various mass transportation systems. Such a new city would be ideally suited to the implementation of the latest technology. The concentration of development along the transportation route would allow certain economies in the supply of utilities and services, as well as insuring that open space would be readily available around and throughout the city. The provisions for transportation, housing, and governmental control should combine to produce a better quality of life for the inhabitants of the linear new city"--Abstract, page …
