Systems Analysis Of Hydrologic Problems, J. Paul Riley, Diana Averett

Reports

Introduction: Increasing national and international interest in water resources in recent years has stimulated much new activity and progress in hydrology. It is now generally recognized that the science of hydrology is basic to an understanding of water resources problems and to planning for water resources development. Accompanying this demand upon the science of hydrology is an urgent need for improved education at the university level. In resopnse to this need for improved education, the First International Seminar for Hydrology Professors was held at Urbana, Illinois, in July 1969. The Second International Seminar was held at Logan, Utah, during August …

An Examination Of Approximately Simultaneous Salt Lake Valley And Cache Valley Clearing (Ventilation) Indexes, George W. Reynolds, William Mcneill, Floyd Johnson, Janet Cleary

Reports

The Clearing Index is a numerical estimate of the contamination dispersal capability of the atmosphere. Between July, 1969, and June, 1970, 192 rawinsonde flights were made in the Cache Valley at approximately the same time as officially scheduled flights at the Salt Lake City Weather Bureau Airport Station. Clearing Indexes were computed from various combinations of Salt Lake Valley and Cache Valley rawinsonde and maximum surface temperature data. These were examined from the viewpoint of recommending a standard procedure for providing Clearing Indexes on a daily basis for Intermountain valleys. The primary conclusions were that: 1. Actual Salt Lake Valley …

Statistical Relationships Between Storm And Urban Watershed Characteristics, V. V. Dhruva Narayana, M. Akbar Sial, J. Paul Riley, Eugene K. Israelsen

Reports

Because of the rapid urban development in recent years, hydrologic problems associated with urban watersheds have gained importance. Large sums of money are being spent for the design of urban drainage systems based upon inadequate procedures for predicting peak runoff rates. In this report a procedure is proposed for predicting peak runoff rates from small urban and rural watersheds based upon measurable storm and watersheds characteristics. The technique was tested for a number of runoff events on the Boneyard Creek watershed at Urbana, Illinois, and the results of this test are included. The procedure will be particularly useful for estimating …

Computer Simulation Of The Hydrologic-Salinity Flow System Within The Upper Colorado River Basin, M. Leon Hyatt, J. Paul Riley, M. Lynn Mckee, Eugene K. Israelsen

Reports

Changes in the hydrologic equilibrium of a river basin resulting from resource development also produce changes in the quality pattern. Since the burden of quality maintenance must be shared by users (just as are quantities) predictions are needed for quality changes which might result from contemplated development at any specified location within the river system. This study reports the development of a computer simulation model of the water and salt flow systems within the Upper Colorado River basin. Because of the close relationship between the hydrologic and salinity flow systems, an understanding of the hydrologic system is essential to successful …

A Thermodynamic Analysis Of A Primary Waste Stabilization Pond, David W. Hendricks

Reports

Traditional design practice for waste stabilization ponds is based upon the premise that sufficient photosynthetic oxygen must be produced within the pond to satisfy oxygen requirements of the incoming waste flow. Thus, because algae production is proportional to pond surface area, surface organic loading rate is a principal design criterion (hydraulic detention time is the other) . That a possible adverse energy trade exists in the sequence of coupled reactions (aerobic waste degradation-photosynthesis) has been largely ignored. This work is focused on quantitatively articulating this energy trade, in terms of algae produced vis a vis waste degraded. This is done …

Bacterial Absorption On Soils--Thermodynamics, David W. Hendricks, Frederick J. Post, Deorao R. Khairnar, Jerome J. Jurinak

Reports

Laboratory studies on the adsorption of bacteria onto soils and activated carbon were undertaken to evaluate the role of the process in removal of bacteria from groundwater. It was hypothesized that removal of bacteria from water passing through soil would be primarily due to adsorption in which case the bacteria would behave in a manner similar to colloidal particles or chemical molecules. The basic kinetics of uptake of Staphylococcus aureus were determined on activated carbon, a highly adsorbing material chemically speaking. Once the technique was worked out and adsorption demonstrated to take place, sand, clay, and Mendon silt loam were …

A Theoretical Study Of Infiltration Into Range And Forest Soils, Joel E. Fletcher, Yehia Z. El-Shafei

Reports

More than 400 rainfall simulator experiments were examined to detect which soil properties could be used to computer infiltration time relationships. Three theoretical equations were tested to determine their efficacy for calculating infiltration time relationships from soil and site characteristics. It was shown that both the modified Green and Ampt and Fletcher equations could by successfully used. Darcian type equations were developed on laboratory type samples which would show the relations between soil, solution and rainfall properties and infiltration. These latter equations have not been tested on undisturbed soils but give excellent agreement between measured and computed values for time …

Ecology Of The Black-Footed Ferret And The Black-Tailed Prairie Dog, Robert G. Sheets

Electronic Theses and Dissertations

Research involving the black-footed ferret (Mustela nigripes) and black-tailed prairie dog (Cynomys ludovicianus) was conducted during 1968 and 1969. Eighteen prairie dog burrows were excavated in 1968 and 1969. Burrow systems ranged from 13 to 109 feet long and 3 to 14 feet deep. Fifteen of the burrows exhibited dome-shaped entrances leading to a gradually descending passageway which made an abrupt vertical ascent to a crater-shaped entrance. Nest chambers were found in 6 burrows. Earthen plugs created by prairie dogs in burrows after ferret departure ranged from 9 to 33 feet long. Eighty-two ferret scats were recovered. Animal remains found …

Pheasant Use And Waterfowl Production On State And Private Lands, Charles R. Elliott

Electronic Theses and Dissertations

Ring-necked pheasant (Phasianus colchicus) use on state-owned game production areas was compared to that on privately-owned areas in east-central South Dakota. Four 80-acre and four 160-acre tracts of state lands were paired with private areas of the same size having the same amount of wetland and were selected from aerial photographs taken before the purchase of the state-owned areas. None of four nests were successful on private areas in 1968 and three of five nests were successful on game production areas. In 1969 three of 19 nests were successful on private areas and 10 of 21 nests were successful on …

Feeding Of Black Bullheads Ictalurus Melas (Rafinesque) In Experimental Cages, Kay R. Hill

Electronic Theses and Dissertations

Black bullheads, Ictalurus melas (Rafinesque), were grown experimentally from July 25, 1969, through October 21, 1969. The fish, collected from Lake Poinsett, were grown in five cages each with a water volume of 2.6 m³ and five cages each with a volume of 3.86 m³. The larger cages contained nearly 60 percent of the total 323 m³ of water volume in the cages. No significant difference in fish growth between the two cage sizes were observed. Fish in large cages gained 204.4 Kg and were fed 1550.8 Kg of food, for a food conversion of 6.60. Fish in smaller cages …

The Ocean Resource: A Scenario For Its Control, Ronald Poitras

Marine Affairs Theses and Major Papers

As man expands his horizons on planet earth, he is beginning to turn increasingly to the oceans as a source of resources, and at a pace commensurate with the growth of his needs and his technical ability. Traditionally the deep sea has always been a "no man's land," an unlimited source of space to be traversed and used infrequently. A scarcity of natural resources and an abundance of human extensions (i.e. technology) are together making deep ocean seclusion a thing of the past. Increasing use of a particular resource is a limited space sooner or later implies an increasing need …

Blind River Dolphin: First Side-Swimming Cetacean, Earl S. Herald, Robert L. Brownell Jr., Fredric L. Frye, Elkan J. Morris, William Evans, Alan Scott

United States Department of Commerce: Staff Publications

The blind river dolphin (Platanista gangetica), first written about by Pliny the Elder in A.D. 72, was found (10 November 1968) to be the first known side-swimming cetacean. The rudimentary eye lacks the lens, but anatomical evidence suggests that the eye may serve as a light sensor. The underwater sound emissions of this species, although similar to those of the Amazon River dolphin (Inia geoffrensis), appear to be produced constantly.

Beggar-Tick Injury To A Northern Cricket Frog And Two Species Of Minnows, Larry A. Witt, Leonard H. Sisson

Nebraska Game and Parks Commission: Staff Research Publications

Various authors have reported on injury to small fishes by achenes of beggar-ticks (Bidem sp.) Reimers and Bond (1966) reported on injury by beggar-ticks to redside shiners, Richardsonius balteatus and young chinook salmon Oncorhynchus tshawytscha. They suggested that presence of beggar-tick plants along banks of hatchery ponds and raceways might be injurious to young of the most aggressive feeders among fish. Allison (1967) described mortality of fingerling coho salmon, Oncorhynchus kisutch, caused by beggar-tick, B. cernuus, achenes. He noted losses of coho salmon 51 to 90 mm in total length held in hatchery raceways. Dead and …

Virus Movement In Groundwater Systems, William A. Drewry

Technical Reports

The purpose of this study is to investigate the extent to which soil acts as an agent in the transmission of waterborne viruses. Since many waterborne outbreaks of viral diseases have involved small wellwater supplies contaminated by effluents from subsurface wastewater disposal systems, there is a great need for such information. Results of this study show that virus adsorption by soils is greatly affected by the pH, ionic strength, and soil-water ratio of the soil-water system and various soil properties. Also, it is shown that one cannot predict the relative virus adsorbing ability of a particular soil based on the …
