Process Control Of Activated Sludge Treatment, Richard I. Kermode, Robert W. J. Brett, Kenneth A. Debelak, John J. Davis

KWRRI Research Reports

General feed forward controllers, conforming to standard control modes, have been derived for an activated sludge process. The analysis indicated that the appropriate controllers are proportional control with measurement of substrate flow rate, and derivative control with measurement of inlet substrate concentration, and manipulation of the rate of return sludge by both controllers.

The performance of these controllers was tested by computer simulation of five dynamic aerator models with and without sludge storage, and with two settling basin models. In all cases significant reduction of the maximum exit substrate concentration was achieved. Additional improvement resulted from the use of sludge …

Remote Sensing Of Earth Resources System Capabilities V.S. Design Constraints, William Howard Grisham

Retrospective Theses and Dissertations

There is new evidence that global earth resources satellite net will be practical. This paper weighs recent advances in remote sensing to pinpoint the dominant constraints. The data and sensor systems interfacing requirements are critically reviewed. It is shown that conventional optics constraints can be relaxed, with the newer systems, based on multi-spectral imagery and statistical processing methods. The most powerful computational methods use algorithms based on a Gaussian assumption for the species vector in feature space, but biases in the imagery limit their efficiency. A rationale is proposed: improving the observational network calibrating efficiency will also improve the photogrammetric …

Channel Improvements, New London, Connecticut: A Case Study, E. L. Gallup

Marine Affairs Theses and Major Papers

The U.S. Army Corps of Engineers is one of the largest single Federal agencies involved in the planning, design and construction of public waterborne transportation facilities. A critical review of a typical corps of Engineers survey report on the improvements to a harbor should provide an insight to the means of allocating the costs and benefits resulting from government expenditures. The purpose of this paper is to review this process using as a vehicle the proposed improvements to the navigation channel at New London, Connecticut

Spatial Variations In The Intra-Urban Response To A Noise Source, Wilbur David Conder

Dissertations and Theses

Most research on the urban sonic environment has been recent. One finding has been that physical noise exposure indices calibrate poorly with human noise response. The vagaries of human response to noise have given impetus to research to isolate the factors that differentiate human response to noise. The present thesis continues this research.

The thesis specifies human noise response to occur on three levels: awareness, annoyance, and complaint. The factors that structure each level of noise response are identified in the published Iiterature.

Noise awareness is a function of noise exposure. Noise annoyance is a function of noise exposure to …

A Regional Perspective For Coastal Zone Management In New England, Susan Holliday Anderson

Marine Affairs Theses and Major Papers

To emphasize the need for a regional perspective of the coastal zone in effective planning in New England, the characteristics that make New England a distinct marine region and the use conflicts that are specific to this region are explored in the discussion that follows.The extent to which the New England states have developed coastal zone management, both in incremental local and state practice and through comprehensive plans, is also discussed. Within New England, there are regional organizations that provide assistance and guidance in matters relating to the coastal zone, but to date, most of their efforts have been directed …

A Comparison Of Consumer's Surplus And Monopoly Revenue Estimates Of Recreational Value For Two Utah Waterfowl Marshes, C. Holden Brink

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Demand curves were estimated for waterfowl hunting and nonconsumptive recreational use from use rate and variable expenditure data collected at the Bear River Migratory Bird Refuge and the Farmington Bay Waterfowl Management Area during fiscal 1969. Consumer's surplus and monopoly revenue estimates were then derived from the demand functions. Adjusted estimates of consumer's surplus for waterfowl hunting amounted to $7,260 per year at Bear River and $11,400 per year at Farmington Bay. For nonconsumptive recreation annual consumer's surplus was estimated to be $18,700 at Bear River and $3,760 at Farmington Bay. Monopoly revenue estimates were between one-half and one-fourth the …

Solid Waste Disposal And Ocean Dumping, John William Sellers

Marine Affairs Theses and Major Papers

A broad-scope overview of the solid waste disposal problem as intensified by legislation against ocean dumping of such wastes. Since the problem of increasing ocean pollution was partly solved by extensive restrictions on ocean dumping, wastes formerly disposed of in the oceans must now be disposed of by other methods. These alternative methods are discussed and cost estimates applied insofar as feasible; effects on the environment and on the conservation of natural resources are also discussed. Efforts should be directed to determine the level of solid waste disposal which would result in beneficial effects, or at the worst, in non-harmful …

A Eutrophication Model Of The White River Basin Above Beaver Reservoir In Northwest Arkansas, Robert A. Gearhart, Dee Mitchell, Louis Thibodeaux, Richard Meyers

Arkansas Water Resources Center Technical Reports

With national interest focused on man’s ever increasing degradation of the waters in this nation, it is clearly evident that an accurate assessment of all parameters influencing water quality needs to be made. Moreover, nutrient levels and budgets reflecting eutrophication trends are important parameters in the overall factors effecting water quality in lakes and reservoirs. The ability to predict future eutrophication levels will greatly enhance the retardation of the eutrophication process. Through mathematical simulation of this process, eutrophication can be analyzed and intelligent decisions regarding water quality management can be made.

Broad Spectrum Microwave Systems For Remotely Measuring Soil Moisture Content, W. P. Waite, K. R. Cook, B. B. Bryan

Arkansas Water Resources Center Technical Reports

A theoretical and experimental study of the microwave reflectivity of soils with varying moisture content was conducted. A system was developed to measure reflectivity over a continuous frequency range of 4 to 26.5 GHz, at incidence angles from 10° to 70°, and with both horizontal and vertical polarization. The measurements were found to be extremely accurate for smooth homogeneous surfaces, however, the effects of surface roughness were found to be more severe than predicted due to the discontinuous nature of naturally occurring rough surfaces. An algorithm was developed which used the frequency dependence of the reflectivity to estimate the effective …

Mathematical Modeling Of Stream Storage Potential, Hugh M. Jeffus

Arkansas Water Resources Center Technical Reports

Streamflow data from unregulated streams in Arkansas were processed through Moran’s Model for a dam. The process involved calculating a cumulative gamma distribution for each stream as the streamflow values were incremented in units of 0.1 cubic feet per second per square mile of drainage area. This gamma distribution was then used as input for Moran’s Model. The output from Moran's Model includes the probability of the reservoir having zero contents as the size of the reservoir is decreased. The logarithm of the probability of zero contents, 1n PO, versus reservoir size, K, is a straight line of the form …

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. …

A Water Resource Management Model, Upper Jordan River Drainage, Utah, Bi-Huei Wang, James I. Felix, Rick L. Gold, Craig T. Jones, J. Paul Riley

Reports

As demands upon available water supplies increase within a river basin, there is an accompanying increase in the need to assess the downstream consequences resulting from changes at specific locations within the hydrologic system. This problem is approached in this study by digital computer simulation of the hydrologic system. Modeling concepts are based upon basic relationships which describe the various hydrologic processes. Within a hydrologic system these relationships are linked by the continuity-of-mass principle which requires a mass balance at all points. Spatial resolution is achieved by considering the modeled area as a series of subbasins. The time increment adopted …

Modification Of A Continuous Ice Crystal Replicator, Paul D. Thornley

Reports

A continuous ice-crystal replicator was modified by the addition of a gear drive to the cating wheel. This modification utilizes a positive drive force on the coating wheel rather than the friction force between the coating wheel and the film. The coating wheel operates successfully for at least 12 hours without slippage or damage to the film. Studies have uncovered several deficiencies in the replicator design which could be corrected. The correction of these deficiencies would lead to an improved quality of ice-crystal replicas. The need for continued studies in the fluid properties of Formvar solution is pointed out. Information …

A Streamflow Simulation Model For A Semi-Arid Region, Adnan A. Saad, L. Douglas James

Reports

A streamflow simulation model which would reproduce the essential feature of the hydrologic regime of a semi-arid region, in this case Jordan, was developmed and described. The model is intended to fit conditions which exist in such a region. The hydrologic processes components which represent the evaporation and the base flow distinguish the Jordan model from others. Development of each function of the model and its constants was based on all the minimal amount of data available. one year of data was used to calibrate the model for Wadi Zerqa watershed. The model was then applied to simualte four years …
