Construction, Instrumentation, And Preliminary Verification Of A Physical Hydrologic Model, Donald L. Chery Jr.
Construction, Instrumentation, And Preliminary Verification Of A Physical Hydrologic Model, Donald L. Chery Jr.
Reports
From theoretical consideration involving a rationalized dimensional analysis of the rainfall-runoff phenomena, dimensionless products of the pertinent variables are derived. These dimensionless products guided the design and construction of a rainstorm simulator and topographic model. The design and construction of these two basic elements of the physical hydrologic model are described. A description of the instrumentation and several relevant calibration tests is followed by a discussion of two preliminary verification test sets. The tests indicated that some necessary refinements in equipment and instrumentation were needed before more precise experimental data could be obtained. Further, the tests produced results which encouraged …
Water Vapor Measurements Using Infrared Absorption, Duard S. Woffinden
Water Vapor Measurements Using Infrared Absorption, Duard S. Woffinden
Reports
Man’s attempt to control the amount of available water has taken two approaches, i.e., weather modification and water storage through the use of man-made reservoirs. In either case, it is necessary to ascertain the water vapor content of the atmosphere. In the case of weather modification, if the water vapor content is insufficient, it is futile to attempt to start precipitation. In the case of reservoirs, it is important to know the evaporation rate since it has been demonstrated that some reservoirs provide a net negative contribution to the total water supply by increasing the normal evaporation losses. Any attempt …

Submergence In A Two-Foot Parshall Flume, Gaylord V. Skogerboe, M. Leon Hyatt, Joe D. England, J. Raymond Johnson
Reports
The primary objective in this study was to ascertain the validity of the method of analyzing submergence developed by Hyatt (1965) in a standard 2-foot Parshall flume. The method of analyzing submergence was first developed for a trapezoidal flume (Hyatt, 1965), was later verified for a rectangular flume (Skogerboe, walker and Robinson, 1965), and has been shown by the authors to be valid for small Parshall flumes (Skogerboe, Hyatt, Johnson, and England, 1965). In view of previous findings, it was felt the method would also be valid for large Parshall flumes, and for this purpose the 2-foot flume was selected. …

Reports
The D.M.A.D. dam and reservoir are located on the Servier River northeast of Delta, utah, and serve as a stroage reservoir for the winter and spring flows of the Sevier River below Sevier Bridge Reservoir. The D.M.A.D. dam has been constructed with two outlet works, one for feeding Canal "A", which serves the Delta and Melville Irrigation Companies, while the other canal serves the Abraham and Desert Irrigation Companies.
A gaging station located along Canal"A" has been used for many years to obtain flow measurements. The gaging station measurements appeared to be very inconsistent, and consequently, in 1963 a study …

SCOPE AND PURPOSE OF INVESTIGATION
The discharge occurring in an open channel can be measured by placing a constriction in the channel. Flumes are commonly used as constriction in open channels. A flume is a specially designed and calibrated section built into a channel, the physical properties of which allow the calculation of the discharge. The narrowest section of the flume is usually called the throat. The velocity of flow through the throat, for any given flow rate, increases with a decrease in the flow depth. The ideal condition for measurement of discharge is a throat sufficiently constricted to produce …

Estimation Of Pan Evaporation From Climatological Data, Jerald Emmet Christiansen, Ashwin D. Mehta
Reports
A new formula and coefficients for climatological factors was developed for estimating pan evaporation based on an analysis of data from 23 states in the U. S. and from five other countries. This formula may be written: Ev=K R Ct Cw Ch Cs Ce Cm in which K is a dimensionless constant R is the theoretical radiation reaching the outer atmosphere, expressed as equivalent evaporation in the same units~ , as Ev. Ct, Cw, Ch,and Cs are dimensionless sub-coefficients for temperature , wind, humidity, and sunshine. Ce is a sub-coefficient for elevation, and Cm is a monthly coefficient Equations were …

The Starling, John L. Long
Journal of the Department of Agriculture, Western Australia, Series 4
Despite their pretty colour and their song, starlings cannot be considered beneficial, especially in the fruit and grain-growing areas of W.A. where they are declared vermin.
MILLIONS of starlings inhabit the settled parts of eastern and south-eastern Australia, but so far they have not reached Western Australia.

Available Water Supply Of The Las Vegas Ground-Water Basin Nevada, Glenn Thomas Malmberg
Publications (WR)
The Las Vegas ground-water basin as described in this report includes the southern part of Indian Spring Valley, Three Lakes Valley, the northern half of Ivanpah Valley, and Las Vegas Valley. These valleys in part are inferred to form a hydrologic unit that includes an area of about 3,000 square miles in the southern part of Clark County, Nev.
The valleys forming the Las Vegas ground-water basin are broad structural depressions surrounded by mountains. The climate of the region is arid, and precipitation in the basin lowlands rarely exceeds 5 inches per year. Drainage is interior except for occasional Hood …

Journal of the Department of Agriculture, Western Australia, Series 4
MANY THINGS must be considered in planning a feed lot.
The site must be well chosen, fencing, gates and yards must be adequate for the cattle carried and feeding and watering facilities should be of a high standard.
Other things to consider are the provision of shelter and shade for the cattle and buildings for feed storage and other purposes.

Submerged Parshall Flumes Of Small Size, Gaylord V. Skogerboe, M. Leon Hyatt, J. Raymond Johnson, Joe D. England
Reports
The calibration of small Parshall flumes for measuring flows ranging in magnitude from 0.1 to 1.1 cubic feet per second (cfs) was accomplished by A. R. Robinson (1960) at Colorado State University. The purpose of Robinson’s investigation was to accurately calibrate and standardize the design of small Parshall measuring flumes. The rated flumes were constructed of galvanized sheet metal. Data was collected for Parshall flumes having throat widths of 1-, 2-, and 3- inches. Calibration tables or curves were prepared for both free and submerged flow. The dimensions of the Parshall flumes rated by Robinson are shown in Figure 1. …

Limnology Of Carbonate – Bicarbonate Lakes In Nebraska, D. B. Mccarraher
Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts
The relation between chemical, physical and biological indices was examined in 1,640 sandhill lakes during the years of 1954 to 1963. Sandhill lakes are formed by either (1) wind deflation basins and closed drainages or (2) exposed ground water table basins. Topography of the 20,000 square mile sandhill region is primarily stabilized dune sand interspersed with wet meadows and pine - cedar - oak river drainage systems. Two-thirds of the area is dune sandhills and one-third occupied by basins, valleys and lakes.
All of the lakes are comparatively shallow, the deepest lake being Blue Lake with 13.8 feet. The average …

Need and Importance of Study
Utah's problems of water use and water supply are becoming increasingly important. They are also becoming increasingly complex as competition for our water resources becomes more keen among various types of uses. In the formulation of plans for sound and efficient use of water it is essential to know the characteristics of occurrence and use of water supplies so that requirements can be balanced most effectively and economically against supply. This ordinarily requires basic hydrologic data to determine relations among climate, water losses, and water yield from watersheds.
Such data are often unavailable - especially …
