Quantification Of Pollutants In Surface Runoff From Agricultural Lands In Brookings County, South Dakota, Leland Lester Harms

Electronic Theses and Dissertations

Surface runoff from snowmelt and rainfall was measured 1n eastern South Dakota from seven sites (7.18 to 18.69 acres) during 1971 and 1972. All sites had single crops which included corn, oats, pasture and hayland. All land was farmed under normal farming conditions. Samples were taken periodically throughout each runoff event, and a single composite sample was made from the individual samples for a particular site. The composite sample represented the entire runoff event. The amount of rainfall and the runoff flow were measured. Determinations on the composite sample included total coliform, fecal coliform, fecal streptococcus, soluble pesticides, specific conductance, …

Nonlinear Optimum Design Of Dynamic Damped Structures, Mark E. Botkin

Doctoral Dissertations

"A method to optimize the weight of plane frames subjected to dynamic loads is presented. Restrictions are imposed upon the maximum dynamic stresses and displacements, desirable section moduli of the constituent members, and the range of values allowed for natural frequencies. Various considerations for rigid frame design include damping, the P-Δ effect, static girder loads, static column loads and girder shears transferred to the columns. A finite difference approach is presented to evaluate the shock spectrum which is used in conjunction with modal superposition to obtain the peak upperbound dynamic displacements and stresses for multistory and multibay frames. The displacement …

Dynamic Instability And Ultimate Capacity Of Inelastic Systems Parametrically Excited By Earthquakes, Wu-Hsiung Tseng

Doctoral Dissertations

"A procedure of analysis is presented for determining the dynamic instability and response of framed structures subjected to pulsating axial loads, time-dependent lateral forces, or foundation movements. Included in the analytical work are the instability criterion of a structural system, the finite element technique of structural matrix formulation, and the computer solution methods.

The dynamic instability is defined by a region in relation to transverse natural frequency, longitudinal forcing frequency and the magnitude of axial dynamic force. The axial pulsating load is expressed in terms of static buckling load for ensuring that the applied load is not greater than the …

A Numerical Technique For Solving Rigid Body Impact On An Incompressible, Viscous Medium, Cecil Thomas Chapman

Civil & Environmental Engineering Theses & Dissertations

A technique for solving rigid-body impact on a viscous, incompressible medium is presented. The numerical scheme is adapted from the Marker and Cell (MAC) method developed to solve problems involving time-dependent motion of a viscous, incompressible fluid in two-dimensional space. As the pressure end velocity fields are computed throughout the flow field, the solution gives the force and displacement time history of the rigid-body during the impact phase. In conjunction with this, through a system of marker particles, the changes in configuration of the viscous medium on impact can be studied. With a "movie frame" (incremental time) approach, computational experimentation …

Manpower And Productivity In The Construction Industry, John A. Purciello

Theses

The relationship between manpower and productivity is an important factor in the area of increasing construction costs. Manpower supply is affected by worker mobility, influx of minority workers, work accidents, and training and apprenticeship programs.

A survey was conducted in the state of New Jersey to determine if a manpower shortage existed. The survey was conducted by submitting questionnaires to contractors, unions, owners, and architect-engineers.

The results of the survey indicated that a manpower shortage does exist, and that the shortage has influ enced construction costs, Furthermore, as a result of the increasing costs, indications of a decline in new …

Simulation Of The Dynamics Of Erodible Streams, Kousoum S. Sakhan

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The movement of translatory waves over an erodible stream has a critical influence on the time of rise of the hydrograph which, in turn, affects the stability of the stream channel. In the present study, the movement of these flood waves is described by the one-dimensional equations of continuity and motion which are obtained by the space integration of the three-dimensional equation of continuity and Reynolds equations. The flow of suspended sediment is described by a one-dimensional dispersion equation which is derived from a three-dimensional equation of conservation of solid mass in the flow. With some modifications the one-dimensional dispersion …

Effects Of Land Use On Water Quality: Summit Creek, Smithfield, Utah, David W. Meyers

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The effects of various land uses on water quality in Summit Creek were evaluated during the period beginning March 13, 1971 and ending October 27, 1971. Potential sources of pollution investigated were: (1) septic tank use, (2) feedlot runoff, (3) urban runoff, (4) rural runoff.

Samples were collected from five sampling stations on 16 separate days during the sampling period. Analyses were performed to determine the following constituents: ammonia, nitrite, nitrate, total phosphorus, orthophosphate, coliform bacteria, chloride, suspended solids, volatile suspended solids, total carbon, organic carbon, temperature and pH.

Agricultural activities, including livestock feedlot operations, were identified as the major …

A Study Of The Effects Of Water Institutions On Planning And Management Of Water Resources In Utah, Donald H. Mclean

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

One area of research that has been somewhat neglected in water planning programs and water development is that pertaining to water law and water institutions. Over the years each state has developed a complex system of water law and organizations for the allocation and distribution of water. The usual role of these institutions is one of orderly development and the efficient use of the water resource. However, in many cases water law and institutions have imposed serious constraints upon the planning and the most efficient use of a valuable resource.

This study, through historic research, has attempted to define these …
