Handbook Of Nebraska Trees: A Guide To The Native And Most Important Introduced Species (Revised 1951), Raymond J. Pool
Handbook Of Nebraska Trees: A Guide To The Native And Most Important Introduced Species (Revised 1951), Raymond J. Pool
School of Natural Resources: Faculty Publications
Nebraska is not to be classified as a forested state since less than 3 per cent of the area of the state is covered by natural timber. However our native forest trees are numerous as to different kinds and their distribution in the state is characterized by many interesting facts. The every-day life of our people is not so commonly associated with trees as is that of peoples in the more wooded states where lumbering and the wood-working industries are very important occupations because of the proximity of great forests of coniferous or broadleaved trees. The people of Nebraska use …
Man And His Water Resource, Dean F. Peterson
Man And His Water Resource, Dean F. Peterson
Faculty Honor Lectures
Several preceding honor lectures have dealt with water. The title of a recent one, "Water and Man," by Dr. Sterling Taylor closely resembles the one for this paper. Dr. Taylor's paper dealt primarily with the physical science of water. This one will consider the nature of the use of water by man and the technological and institutional structure related to that use. Thus there should be no serious overlap. My friends in the social sciences may be surprised, too, to find that somehow this lecture has spilled over into their territory. But engineering is the implementation of science and technology. …
Stage-Fall-Discharge Relations For Flood Flows Over Highway Embankments, Gaylord V. Skogerboe, M. Leon Hyatt, Lloyd H. Austin
Stage-Fall-Discharge Relations For Flood Flows Over Highway Embankments, Gaylord V. Skogerboe, M. Leon Hyatt, Lloyd H. Austin
Reports
At Utah State University, considerable effort has been devoted to the analysis of submerged flow at open channel constrictions. A method of analyzing submerged flow was first developed for a trapezoidal flume by Hyatt (1965). Later studies verified the method of analysis for a rectangular flume (Skogerboe, Walker, and Robinson, 1965) and Parshall flumes (Skogerboe, Hyatt, England, and Johnson, 1965). Because of the previous findings, it was felt this method of analyzing submerged flow could be applied to highway embankments.
A highway embankment is a form of broad-crested weir when overtopped by flood waters. Being a weir, the flood discharge …

Subcritical Flow Over Various Weir Shapes, M. Leon Hyatt, Gaylord V. Skogerboe, Lloyd H. Austin
Subcritical Flow Over Various Weir Shapes, M. Leon Hyatt, Gaylord V. Skogerboe, Lloyd H. Austin
Reports
Submerged flow exists for any given structure when a change in flow depth downstream from the structure causes a change in flow depth upstream from the structure for any given constant value of discharge. The two flow depths, normally measured when submerged flow exists, consist of a depth upstream from the structure, which is used also for free flow conditions, and a depth of flow located any place downstream from the structure. The initial studies in which the submerged flow analysis was developed were made on flat-bottomed flumes (Hyatt, 1965; and Skogerboe, Walker, and Robinson, 1965). Later studies verified the …

Measuring Water With Parshall Flumes, Gaylord V. Skogerboe, M. Leon Hyatt, Joe D. England, J. Raymond Johnson
Reports
Preface: As the value of water increases, the extent to which measurement is employed in an irrigation system also increases. Additional flow measurements provide information for improved management of the water supply. Good water management requires accurate measurement. Many devices have been developed for this purpose and are in use. Included among them are weirs, orifices, calibrated gates, Parshall flumes, and current meters. Of these, the Parshall flume is one of the most widely accepted and used. Presented in this publication is a discussion concerning the use of Parshall flumes for measuring water, including the utilization of a new approach …

Application Of Electronic Analog Computer To Solution Of Hydrologic And River Basin Planning Problems: Utah Simulation Model Ii, J. Paul Riley, Duane G. Chadwick, Jay M. Bagley
Reports
As demands upon available water supplies increase, there is an accompanying increase in the need to assess the downstream hydrologic system. At Utah State University this problem is being approached by electronic analog simulation of the hydrologic system. Modeling concepts are based upon the development of basic relationships which describe the various hydrologic processes. Within a system, these relationships are linked by the continuity -of-mass principle which requires a hydrologic balance at all points. Once established, the model is applied to any particular geographic unit by determining the appropriate constants of the hydrologic equations. The analog computer is ideally suited …

Evaluation Of Free And Submerged Flow Data For Large Parshall Flumes, M. Leon Hyatt, Gaylord V. Skogerboe
Evaluation Of Free And Submerged Flow Data For Large Parshall Flumes, M. Leon Hyatt, Gaylord V. Skogerboe
Reports
Because the accurate measurement of water plays such an important part in water management, such structures as weirs, orifices, calibrated gates f and flumes have been developed. These structures provide the means for reasonable measurement of the smaller flows (1: .. 100 cfs), but for the large flows (100-3,000 cfs) the current meter, large Parshall flume, and various other flumes are commonly used. Where a permanent structure is required, the most widely accepted and utilized method for measurement of large flows is probably the Parshall flume. The purpose of this report has been to collect the existing flow data for …
Mathematical Hydraulics Of Surface Irrigation, Cheng-Lung Chen
Mathematical Hydraulics Of Surface Irrigation, Cheng-Lung Chen
Reports
The general hydrodynamic equations for a spatially varied unsteady flow in a prismatic open channel having an arbitrary cross-sectional shape can be derived from the equations of continuity and momentum. The assumptions based on the general concept of hydrodynamics and the theory of shallow water is introduced. The mathematical models in the surface irrigation can be formulated by these equations of motion with the appropriate initial and boundary conditions prescribed at the singularity point (the origin in the x, t-plane) and at x = 0. Therefore, the flow in the surface irrigation must be described by solving the boundary-value problem …
