Boundaries and Water: Allocation and Use of a Shared Resource (Summer Conference, June 5-7)
Conference organizers and/or faculty included University of Colorado School of Law professors David H. Getches, Lawrence J. MacDonnell and Charles F. Wilkinson.
Boundaries and Water: Allocation and Use of a Shared Resource is the topic of the Center's annual summer program on water this June. Most of the major rivers in the western United States are shared between two or more states. Often tribal governments play an important role in water allocation and use decisions. International considerations also may be involved in some cases. These interjurisdictional issues extend to groundwater as well as surface water.
This conference will provide the …

Tb136: Methodology Development For Study Of Root Influences On Nitrogen Mineralization, M. S. Erich
Tb136: Methodology Development For Study Of Root Influences On Nitrogen Mineralization, M. S. Erich
Technical Bulletins
The current study was designed to explore a particular set of methodologies for addressing the question of whether plant root growth affects the rate of N mineralization. Specifically, the experimental design involved supplying plants with only organic N as manure and no nitrate. A highly sandy growing medium was used in an attempt to prevent overly wet conditions in the pots. In addition, instead of only comparing planted and unplanted pots, four different planting densities (0, 1, 2, 3 plants per pot ) were used as treatments.

Simulation Of The Fate Of Nitrogen From The Disposal Of Poultry Litter, H. D. Scott
Technical Reports
A PC/AT computer model was developed to simulate the transport of water, nitrate and ammonia in the soil profile after an application of poultry litter to pasture. The model was written using FORTRAN 77 compiler and can be used on any IBM type compatible computer with a math coprocessor. Poultry litter has been shown to be a potential source of plant nutrients, but mismanagement can result in nitrate pollution of the surface and groundwater. The model is composed of a main program, 11 subroutines and three subprograms. An example was shown of the flexibility and dynamic nature of the computer …

Determining Pesticide And Nitrate Levels In Spring Water In Northwest Arkansas, T. L. Lavy, B. A. Dehart, John D. Mattice
Technical Reports
Occurrences of pesticides in our nations ground water are on the rise. As states become aware of this problem and begin monitoring programs, incidence of contamination will probably increase. Since the problem of pesticides in groundwater is relatively new, little research has centered on the fate of pesticides after they reach the groundwater environment. In Northwest Arkansas efforts to monitor groundwater for pesticides have been small. Twenty-five springs in Northwest Arkansas were sampled in the fall of 1988, and spring of 1989. Analysis for atrazine, alachlor, metolachlor, diuron, and simazine in spring water was preformed using gas liquid chromatography and …
An Expert System For Managing An Activated Sludge Wastewater Treatment Plant, Sandra C. Parker, David G. Parker
An Expert System For Managing An Activated Sludge Wastewater Treatment Plant, Sandra C. Parker, David G. Parker
Technical Reports
A diagnostic expert system for an activated sludge wastewater treatment plant has been designed to link with a relational database management system for obtaining operational parameter values that are used by the program to diagnose operational problems that may occur in the process. The problems that are dealt with by the system are bulking sludge, floating sludge, defloculation, ashing, solids washout, foaming problems, high soluble effluent BOD and problems in the aeration system. The link between the expert system and the database is accomplished via programming that is initiated by the expert system program. The operator of the system is …
Presentation Of Verified Algal Taxa As Reference Sources, Richard L. Meyer
Presentation Of Verified Algal Taxa As Reference Sources, Richard L. Meyer
Technical Reports
A data base of the algae of Arkansas ecoregions has been established to describe the numerous taxa that occur within the aquatic ecosystems included in these regions. The organisms were identified with the aid of diverse literature from throughout the world. These sources are written in multiple languages and the living organisms had to be compared with outline or silhouette drawings. These illustrations may include shading, but none present the true color of the organism but only the characteristics of the descriptive source. Primary characteristics used to identify algae is based upon pigmentation of the plastid and the number and …
Improving Irrigation Scheduling And Water Use Efficiency In Cotton, Derrick M. Oosterhuis
Improving Irrigation Scheduling And Water Use Efficiency In Cotton, Derrick M. Oosterhuis
Technical Reports
Cotton (Gossypium hirsutum L) is an important crop in the southern United States. The crop is grown in both irrigated and rainfed situations and is seldom free from periods of water shortages at some stage during the season. In recent years the need for consistency in yields and a stable cash flow has resulted in a rapid expansion in the number of irrigated acres of cotton in the Mississippi Delta. Irrigation research has, however, not kept pace with this expansion. This project represents a start at meeting this urgent need. The influence of weather patterns necessitates that these studies be …

Hypoxia In The Lower Rappahannock Estuary, Albert Y. Kuo, Mohamed Z. Moustafa
Reports
There are several objectives to this study. The immediate objective is to collect a comprehensive and consistent set of field observations to better describe the hypoxic condition in the Rappahannock River. Other objectives can be classified as short and long term goals.
Long term: (1) Identify and quantify the processes contributing to the dissolved oxygen budget in deep waters, and explain the variabilities among the three Virginia major tributary estuaries. (2) Provide information for resource management so that the James River can be protected from hypoxic problems and, perhaps, the problems in the York and Rappahannock Rivers can be alleviated. …
A Laboratory Characterization Of Pulp And Paper Mill Solid Wastes For Potential Use As Hydraulic Barrier Material In Landfill Covers, Carleton Van Maltby
A Laboratory Characterization Of Pulp And Paper Mill Solid Wastes For Potential Use As Hydraulic Barrier Material In Landfill Covers, Carleton Van Maltby
Masters Theses
Fifteen sludges from wastewater treatment systems of pulp and paper mills that encompass major production categories, and eight fly ashes from mill boilers incinerating wood waste, coal, or their combination were characterized for their potential suitability as hydraulic barrier material. Hydraulic conductivity was observed to range over four orders of magnitude for the materials tested.
Minimizing The Potential For Groundwater Contamination From Agricultural Point Sources, Joseph H. Massey, Terry L. Lavy, John D. Mattice
Minimizing The Potential For Groundwater Contamination From Agricultural Point Sources, Joseph H. Massey, Terry L. Lavy, John D. Mattice
Technical Reports
An activated charcoal filtration unit was designed to remove pesticides from leftover pesticide solutions and rinsates generated under farm-like conditions. The system, fabricated for less than $1400 using readily available components, effectively removed the pesticides atrazine, benomyl, carbaryl, fluometuron, metolachlor, and trifluralin from wastewater generated on the University of Arkansas Agronomy Farm located in Fayetteville, AR. A total of 2253 L of wastewater were treated using the system. Of these 1768 L were generated from washing out the spray tank (rinsates) while 485 L stemmed from leftover pesticide solutions that were mixed, but not applied. Typical initial pesticide concentrations in …
Analysis, Design And Implementation Of A Pilot Relational Database For Groundwater In The State Of Arkansas, Ray Hashemi-Nassab
Analysis, Design And Implementation Of A Pilot Relational Database For Groundwater In The State Of Arkansas, Ray Hashemi-Nassab
Technical Reports
There are several agencies within the state of Arkansas dealing with underground water. Each agency has its own database that acts as an isolated depository of data. Practically, the communication among these databases is zero, not because there is no need for it, but because the communication is very difficult if not impossible. Data redundancy, inconsistency, and lack of integrity is overwhelming. In this study we have addressed the problem of lack of unity among the databases belonging to different agencies. Also, as an alternative we have developed a relational database. In this database the data was normalized to 4NF. …

Paleogeography And Paleoenvironments Of The Lower Unit, Fossil Butte Member, Eocene Green River Formation, Southwestern Wyoming, Roberto Enrique Biaggi
Loma Linda University Electronic Theses, Dissertations & Projects
During Eocene time sediment accumulated in Fossil Lake, in what developed to be a small linear and structurally controlled basin. Fossil Lake was one of several lakes into which the Green River Formation was deposited in Wyoming, Utah and Colorado.
Detailed stratigraphic analysis of the Lower Unit of the Fossil Butte Member revealed a well developed lacustrine sequence south of Fossil Butte, and indicates four major depositional facies: (1) open lacustrine, (2) marginal lacustrine, (3) carbonate mudflat, and (4) marginal fluvio-deltaic. The open lacustrine facies is characterized by kerogen rich to kerogen poor finely laminated micrites , that consist mainly …
Geology In The Vicinity Of The City Of Fossil, Wheeler County, North-Central Oregon, Patrick W. Riseley
Geology In The Vicinity Of The City Of Fossil, Wheeler County, North-Central Oregon, Patrick W. Riseley
Loma Linda University Electronic Theses, Dissertations & Projects
The area of study is located on the north flank of the northeast-southwest trending Blue Mountains Anticlinorium in north-central Oregon. The primary geologic problems investigated were: 1) the age and stratigraphic position of leaf-bearing tufts mapped as Oligo-Miocene John Day Formation but surrounded by andesitic basalts of the Eo-Oligocene Clarno Formation, 2) the age of "olivine basalt" mapped as John Day Formation by some workers but referred to the Clarno Formation by others, and 3) the petroleum potential of the Fossil area.
To resolve these three problems I mapped a 25 square mile area surrounding Fossil at 1 :24,000 scale. …
Taylor Instability In Ryholite Lava Flows, B. A. Baum, W. B. Krantz, Jonathan H. Fink, R. E. Dickinson
Taylor Instability In Ryholite Lava Flows, B. A. Baum, W. B. Krantz, Jonathan H. Fink, R. E. Dickinson
Geology Faculty Publications and Presentations
A refined Taylor instability model is developed to describe the surface morphology of rhyolite lava flows. The effect of the downslope flow of the lava on the structures resulting from the Taylor instability mechanism is considered. Squire's (1933) transformation is developed for this flow in order to extend the results to three-dimensional modes. This permits assessing why ridges thought to arise from the Taylor instability mechanism are preferentially oriented transverse to the direction of lava flow. Measured diapir and ridge spacings for the Little and Big Glass Mountain rhyolite flows in northern California are used in conjunction with the model …
