Submergence In A Two-Foot Parshall Flume, Gaylord V. Skogerboe, M. Leon Hyatt, Joe D. England, J. Raymond Johnson
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. …

Foreward: Recognizing the need for training of individuals to meet the rapidly rising problems connected with water resources development, Utah State University, with National Science Foundation support, organized a Summer Institute in Water Resources for college teachers. it was hoped that participants carefully selected from all regions of the country would receive additional insight and stimulation to improve and enlarge water resources training programs at their own institutions. Thus, the accelerated dissemination of such knowledge on a national scale could be facilitated. Realizing further that the key to a successful institute of this nature lay in the excellence of its …

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 …
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 …

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 …
Calibration Of Irrigation Headgates By Model Analysis, Gaylord V. Skogerboe, Vaughn E. Hansen
Calibration Of Irrigation Headgates By Model Analysis, Gaylord V. Skogerboe, Vaughn E. Hansen
Reports
Introduction
The purpose of this research project was to calibrate the slide gates used by the D.M.A.D. Company (Delta, Melville, Abraham and Deseret Irrigation Companies). These gates, which number more than 600, are located throughout the distribution system. Each gate is placed in a concrete box 4 feet wide, 3-1/2 feet deep and 4 feet long. The structure is used as a means of diverting the water and is also used as a measuring device.
A similar structure, but with a different type of slide gate, was calibrated in 1914. At the time rating tables were prepared which listed the …

Aerial Application Of Evaporation-Reducing Chemicals, Development And Evaluation Of Equipment And Techniques, C. Earl Israelsen, Vaughn E. Hansen
Reports
Aerial applications of both liquid and powder evaporation retardants have been made in parallel strips on large lakes for purposes of comparison. Films formed from powder spread more rapidly than did those from liquid, but usually both films ultimately spread to approximately equal widths and had the same degree of compression as determined with indicator oils. Evaporation retarding materials with large numbers of particles having diameters smaller than 75 microns are greatly affected by the wind. As the chemical is dispensed from the airplane. the fine particles drift with the wind and in some instances are carried onto the land …

Developing A State Water Plan Utah's Water Resources--Problems And Needs--A Challenge, Utah Water Research Laboratory
Reports
Of all the natural resources with which Utah has been endowed none is more vital to the social and economic well-being of the people than it water resource. We cannot manufacture water. We have found no acceptable substitute. Not one more drop of water is available for our use today than was available to the pioneers. Yet water uses and water demands have multiplied over the years. Since we can do little to change nature's water allotment to Utah we must learn how to utilize our existing supplies more judiciously. This means devoting increasingly more attention to problems of water …

This report reviews activities on this project since the Progress Report, Part IV, June 1961.
The summer of 1961 has been one of the driest on record for Ogden Bay and Howard Slough Refuge. The extreme shortage of irrigation water has resulted in very little flow in the Howard Slough which originates from return flow. The available water from the Weber River for the Ogden Bay Refuge was also the lowest on record. The scarcity of water at these two refuges has resulted in increased salinity.
Most of the routine work on the project during the summer was done by …

A Rational Approach To The Estimation Of Evaporation And Evapotranspiration From Climatological Data, Jerald Emmet Christiansen, B. B. Patil
Reports
Many attempts have been made to derive mathematical expressions relating evaporation and evapotranspiration, or consumptive use, to climatological data. IN the United States, the Blaney-Criddle formula is probably the best known for estimating consumptive use (2 and 3). Blaney (1) has also suggested that this formula is suitable for estimating evaporation as measured with a Weather Bureau pan. Other well known formulas are the Penman formulas (10), the Thornthwaite formula (15) and the Hargreaves formulas (8). Halkias, Beihmeyer and Hendrickson (6) suggest that water requirements of crops can be determined from atmometer data. Lowry and Johnson (() in an early …

The data included in this report have resulted from a series of monthly offshore cruises conducted by the Ichthyology Research Section. The cruises were made to obtain information on the distribution and abundance of pelagic eggs and larvae of fishes. Since the biological results will be reported in a series of separate papers (Joseph, Massmann and Norcross, 1961), it was felt that the raw hydrographic data shpuld be made available in a single source.

Irrigation And Drainage Problems In Uruguay, Jerald Emmet Christiansen
Reports
Synopsis: Uruguay irrigates about 65,000 acres, mostly rice (74%) and sugar cane (15%). Summer rainfall averages about 3.5 in. per month, but frequent droughts seriously affect both crops and livestock. Irrigation can be increased by storage in small reservoirs on tributary streams by means of low earth dams. Some areas will require flood control and draiange before intensive agriculture can be practiced.
