The Growing Season, Department Of Agriculture, Western Australia, Bureau Of Meteorology

Journal of the Department of Agriculture, Western Australia, Series 4

IN AUSTRALIA the seasons of summer, autumn, winter and spring do not have the importance that they have in the Old World, and though summer and winter weather are quite different, there is not the obvious difference in autumn and spring conditions that there is in the colder countries.

This is largely due to the difference in vegetation and in its life cycle in the different places.

U.S. Research On Whales, Robert L. Brownell Jr.

United States Department of Commerce: Staff Publications

The United States is a member of the International Whaling Commission (IWC) and thus shares responsibility with 13 other countries for conducting research on whales. In 1958, our research program was moved from La Jolla, California, to the Marine Mammal Biological Laboratory in Seattle under the direction of the Bureau of Commercial Fisheries (BCF), Department of Interior. This move consolidated the scientific staff, libraries, and facilities used for marine mammal research. The legislation that created the Bureau made this organization the one responsible for decisions regarding the use of whale resources.

Soil Conservation means, basically sound land management. With good management the Ste's resources of productive land can be bot only maintained but actually improved. It is a question of deciding the best use for each soil type and situation. Profitable Production must be kept up in changing economic conditions without destroying land assets in the process.

The Control Of Algae, G R W Meadly

Journal of the Department of Agriculture, Western Australia, Series 4

CONDITIONS in areas of still, stored water in Western Australia can easily become ideal for the development of algae and control measures may become necessary in farm dams and swimming pools.

Part I - Controlling The Soil Moisture Environment Of Transpiring Plants, Part Ii - Prediction Of Leaf Temperature Under Natural Atmospheric Conditions, Charles T. Haan, Billy J. Barfield, Robert Edling

KWRRI Research Reports

Part I

A technique for controlling the soil moisture potential in the root zone of transpiring plants was developed. The method uses the principles of unsaturated flow through a porous media to develop the desired moisture potential. In the case of non-steady state transpiration, the maximum possible fluctuation in the soil moisture potential can be determined by the techniques presented.

Part II

Two implicit leaf temperature prediction equations were derived from the energy balance approach. The equations define sensible and latent heat transfer from a plant population as a two step process:

1. Transfer between the plant leaf and the canopy …

Emergency Chlorination Of Farm Water Supplies, H C. Hughes

Journal of the Department of Agriculture, Western Australia, Series 4

TOWARDS the end of summer (and especially in a drought) the risk of water in dams, soaks, wells or tanks becoming polluted is increased.

Bore water is much less likely to be affected unless the bore is poorly sited near a farm building, such as a shearing or milking shed, a pig pen, or a septic tank system.

Water Conservation : The Storage Life Of Farm Dams, D J. Carder

HOW MANY stock can a dam of a certain size and depth be expected to carry and how long will the supply last?

What size of dam is needed in case the winter rains fail? How many stock can a dam support and still provide a drought supply?

Effects Of Aldrin On Young Pen-Reared Pheasants, Joseph Edward Hall

Electronic Theses and Dissertations

Three levels of encapsulated aldrin (.05, 1.0, and 1.5 mg) were administered weekly to young pen-reared pheasants from 5 to 11 weeks of age to determine effects on growth and residue levels in brain, feathers, and whole body during and after treatment. During treatment, birds were weighed weekly. After treatment ceased, birds were weighed every other week until 21 weeks of ---. Analysis of residues was by electron capture gas chromatography. Growth of pheasants --- 5 to 21 weeks of age was depressed (P 0.01) by administration of aldrin dosages of 1.0 to 1.5 mg. Aldrin values in the brain …

An Evaluation Of Relationships Between Streamflow Patterns And Watershed Characteristics Through The Use Of Opset, L. Douglas James, William O. Thompson, Glendon Allen Ross, Earnest Y. Liou

KWRRI Research Reports

Selection among alternative flood control measures would be better informed if better information could be obtained on the marginal change in flood hazard associated with land use and other changes in the tributary watershed. Hydrologic modeling is the most promising approach to answering this question; however, the use of existing models is hampered by the absence of information correlating model parameters with physical characteristics of the watershed.

To deal with this situation, a method was developed for estimating the parameter values for the Stanford Watershed Model which best match recorded with simulated streamflows. Physical characteristics were measured for 17 rural …

Factors Affecting Relocation In Response To Reservoir Development, Rabel J. Burdge, Richard L. Ludtke

KWRRI Research Reports

The focus of this paper is on the question of how rural people anticipate forced moves as a result of flood control projects and how they change their life in accepting separation from familiar surroundings.

A model of faced migration is presented which sees the variables of socioeconomic status, knowledge of reservoir projects, vested interests and the degree of identification with place of affected persons as producing differential apprehension over moving. Differential apprehension is then seen as producing different attitudes toward the project which will influence the type of migration plans.

To test this model of forced migration, data were …

Anticipations Of Change: A Socio-Economic Description Of A Kentucky County Before Reservoir Construction, Charles Robert Smith

KWRRI Research Reports

In the past the construction of large reservoirs in the United States has been evaluated largely in terms of the economic benefit they bring to the area where they are constructed and to the nation. Where human populations are involved, however, a host of social changes occur, many of which fundamentally alter the way of life of a people.

This report is part of a larger study which aims at analyzing the social costs and benefits of reservoir construction. The project is long range in that studies are to be carried out before, during, and after construction. This report concentrates …

Opset Program For Computerized Selection Of Watershed Parameter Values For The Stanford Watershed Model, Earnest Yuan-Shang Liou, L. Douglas James

KWRRI Research Reports

The advent of high-speed electronic computer made it possible to model complex hydrologic processes by mathematical expressions and thereby simulate streamflows from climatological data. The most widely used program is the Stanford Watershed Model, a digital parametric model of the land phase of the hydrologic cycle based on moisture accounting processes. It can be used to simulate annual or longer flow sequences at hourly time intervals. Due to its capability of simulating historical streamflows from recorded climatological data, it has a great potential in the planning and design of water resources systems. However, widespread use of the Stanford Watershed Model …

Evaluation Of The Social Impact Of Reservoir Construction On The Residential Plans Of Displaced Persons In Kentucky And Ohio, Richard L. Ludtke, Rabel J. Burdge

KWRRI Research Reports

The states of Kentucky and Ohio have numerous reservoir projects at various stages of planning and construction. Each of the projects produces substantial social impact for the residents of the area and particularly for those persons affected by a loss of property and homes. This impact is not uniform in that people respond differently to displacement and the methods of adjusting relocation are known to differ among people.

This research was initiated to develop and test a model for explaining migration under such conditions. The model includes a consideration of people's potential for transferring existing statuses to new residences, the …

The Economic Value Of Natural Areas For Recreational Hunting, Kenneth Gene Holbrook

KWRRI Research Reports

The pressures of population growth, urbanization, and improved transportation are diminishing the availability of quality naturalistic sites for recreation while at the same time producing greater demands for their use. One cause contributing to the reduction in acreage in naturalistic areas is the construction of reservoirs. The recreational hunting value of the naturalistic area to be inundated should be considered as a negative consequence in the economic evaluation of a proposed reservoir site.

This study utilized hunting data collected by the Kentucky Department of Fish and Wildlife, from the 120 Kentucky counties to estimate the economic, value of the average …

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 …

Subcritical Flow At Open Channel Structures Bridge Constructions, Gaylord V. Skogerboe, Lloyd H. Austin, Kuan-Tao Chang

Reports

The techniques previously employed by the writers for describing subcritical flow at open channel constrictions have been found valid for analyzing nonuniform flow in open channels. Combining the nonuniform flow analysis with the submerged flow ratings for various bridge geometrics has provided an analytical means for determining the backwater due to the bridge constrictions under “abnormal stage – discharge” conditions.

Computer Simulation Of Water Resource Systems At Utah State University, J. Paul Riley

Reports

Introduction: The problems of managing water-resource systems are basically those of decision making based upon a consideration of the physical, economic, and sociological processes involved. These processes are strongly interrelated and constitute a dynamic and continuous system. Any combination of these interrelated and numerous system variables yields a management solution. At Utah State University the problem of investigating system response to various possible management alternatives is being approached by hybrid computer simulation. The concept of simulation is fundamentally simple. Basically, it is a technique of analysis whereby a model is developed for investigating the behavior or performance of a dynamic …

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 …
