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:
- Transfer between the plant leaf and the canopy …

OES Faculty Publications
The coast of the Middle Atlantic Bight of North America's Atlantic shelf consists of a series of spit - barrier island systems attached on their northern ends to eroding headlands. It has been suggested that these barriers were generated as coastwise-prograding spits (Fisher, 1967) or alternatively as mainland beaches detached by the Holocene rise of sea level (Hoyt, 1967). The shore face before the barriers consists of fine, seaward-fining sand. Locally, it is corrugated by oblique-trending ridges with up to 8 metres of relief — see for instance CSGS Chart 1109. Beyond the shore face lies a vast submarine sand …

A Fluorescent Tracer Study At A Tidal Inlet (Rudee Inlet, Virginia), James W. Bunch
OES Theses and Dissertations
Patterns and approximate rates of littoral transport south of Rudee Inlet. Virginia were investigated with fluorescent tracers. Sand movement was traced under a variety of longshore current and wave conditions. Patterns of tracer dispersal reflected the importance of wave height, breaker angle, and longshore current velocity on modes of littoral transport. A direct relationship between angle of breaker incidence. generated longshore current. and direction of tracer sand movement was found. Onshore offshore paths were taken by tracer material during periods of weak longshore currents and small breaker angles while alongshore paths were followed by tracer material during strong longshore currents …

The survey results indicate that the impoundment of water behind Hoover Dam has not adversely affected the dissolved oxygen (DO) content and that water quality and DO content were uniform regardless of depth. The study made in April-May 1964 will provide water quality data of Lake Mead prior to releases from Lake Powell as a basis for evaluating Lake Powell's effect on water quality and limnology of Lake Mead. The performance of a DO analyzer was tested and found unsatisfactory at depths below 150 ft. Parameters tested by standard chemical analyses of water samples in the Denver Laboratory and by …

A Comparison Between The Direction Of Tornado Movement And The Associated 500 Mb. Level Wind Direction, Allen B. Johnson
Journal of the Minnesota Academy of Science
An investigation to ( 1) determine the 500-milli-bar level weather patterns associated with tornadoes moving from northwest toward southeast and from southwest toward northeast and, (2) show the significance of the contrasts between the 500-mb. level weather patterns of the two tornado types. A very high relationship between the direction of the 500-mb. level winds and the tornado direction was substantiated by a coefficient of correlation of +0.88. The typical 500-mb. level low center associated with the northwest to southeast type tornado was located over Hudson Bay about 1300 miles north-northeast of the tornado area. The low center associated with …

Interbasin Movement Of Ground Water At The Nevada Test Site, Isaac J. Winograd
Interbasin Movement Of Ground Water At The Nevada Test Site, Isaac J. Winograd
Publications (WR)
The present paper presents hydraulic evidence for the interbasin circulation of ground water through carbonate rocks of Paleozoic age at the Nevada Test Site. An integral part of this evidence is the discovery that aquifers in alluvium and tuff, formerly thought to be the principal aquifers at the Test Site, are semiperched above a thick tuffaceous aquiclude that separates them from the carbonate rocks.
This paper is based on one of the studies being made by the Geological
/="/">Survey for the Atomic Energy Commission. These studies seek to evaluate

An Index To The Literature On Digenetic Trematodes From Fishes, Richard William Bond
University of the Pacific Theses and Dissertations
The primary purpose of this compilation is to facilitate for pertinent literature in the searches involving digenetic trematodes from fines. The index may be used by the investigator to determine what, Af any, 14torature has appeared concerning the animal or group of animals with which he is working; and the literature is cross-indexed in such a way that it may be approached from the various angles commonly used in trematodes investigations. There are included, for example, an index to hosts, an index to larval stages of development and a partial geographic index to adult trematodes of fishes.

Water Levels And Artesian Pressure In Wells In Las Vegas Valley And In Other Valleys In Nevada, 1913-1945, T. W. Robinson, George B. Maxey, J. C. Fredericks, C. Harry Jameson
Water Levels And Artesian Pressure In Wells In Las Vegas Valley And In Other Valleys In Nevada, 1913-1945, T. W. Robinson, George B. Maxey, J. C. Fredericks, C. Harry Jameson
Publications (WR)
The rock formations of the earth are great natural reservoirs in which a part of the water derived from rain and snow is stored. Water levels and artesian pressure in wells register the stages of these natural reservoirs. The changes in water levels or artesian pressure are indicative of the depletion or replenishment of the natural reservoirs. Systematic and periodic measurements of water levels and artesian pressure in wells have been made in Nevada, by State and Federal agencies from time to time. However, only a few of these measurements have ever been published. Under the cooperative arrangement between the …

Progress Report On The Ground-Water Resources Of The Las Vegas Artesian Basin, Nevada, George B. Maxey, C. Harry Jameson
Publications (WR)
Whether the tremendously increased population acquired by Las Vegas in the years 1940 to 1942 will be retained cannot at present be foretold. However, the valley will undoubtedly be expected to support a considerably larger population than it did at any time prior to 1940, and continually increasing demands on the water supply for innumerable pcacetimc activities must be anticipated. Therefore, a sound evaluation of tho ground water resources of Las Vegas Valley is directly in line with the other wisely progressive planning programs which are now operating or are taking shape in the valley as well as in the …
