Management For Deer, John D. Byelich, Jack L. Cook, Ralph I. Blouch Jan 1972

Management For Deer, John D. Byelich, Jack L. Cook, Ralph I. Blouch

Aspen Bibliography

Deer in the Lake States are declining. Early stages of second growth forest following the logging era favored deer. Aging and successional changes toward more tolerant types are causing range deterioration. Aspen is the major deer-producing forest type. Commercial harvest of aspen improved deer range, but not enough is taking place to reverse the downward trend of deer or to save the type from conversion. Additional efforts to cut of otherwise treat aspen stands specifically for deer have been of token size. Michigan has earmarked a deer license increase for range improvement and is now embarked on a large scale …

Stemflow In A Multi-Storied Aspen Community, J.R. Clements Jan 1972

Stemflow In A Multi-Storied Aspen Community, J.R. Clements

Aspen Bibliography

This report presents results of a stemflow study in a 5-year-old, dense, sucker stand of largetooth aspen [Populus grandidentata Michx.]. The purposes of this study were to determine the relation of stemflow volume per tree to gross rain per storm, to determine the proportion of gross rain reaching the ground as stemflow, and to derive an equation to predict rain equivalent of stemflow from gross rain for use in other studies of water relations of this sucker stand.

Effect Of An Aspen Clearcutting On Water Yield And Quality In Northern Minnesota, Elon S. Verry Jan 1972

Effect Of An Aspen Clearcutting On Water Yield And Quality In Northern Minnesota, Elon S. Verry

Aspen Bibliography

The impact of different forest types on streamflow or groundwater recharge must be considered in evaluating multiple-use alternatives. The impact of species conversion on streamflow has been directly measured at the Coweeta Experimental Watersheds in North Carolina. However, the use of net precipitation1 data, with appropriate cautions, provides a practical basis for estimating water yield differences between forest types where long-term streamflow comparisons are not available.

Studies To Develop And Investigate An Inverse Formulation For Numerically Solving Three-Dimensional Free Surface Potential Fluid Flows, Roland W. Jeppson Jan 1972

Studies To Develop And Investigate An Inverse Formulation For Numerically Solving Three-Dimensional Free Surface Potential Fluid Flows, Roland W. Jeppson

Reports

An inverse formulation is developed for solving three-dimensional potential fluid flows which considers the magnitudes of the cartesian coordinates x, y, and z as the dependent variables in the space defined by the potential function and two mutually orthogonal stream surface functions whose intersection defines the physical space streamlines. This formulation reverses the usual role of the variables. In this inverse space irregular boundaries, with unknown position in the physical space, such as free surfaces become plane boundaries, and the space of most potential flow problems is a parallelepiped. The basin partial differential equations resulting from this formulation are nonlinear …

Osiris, God Of Ancient Egypt And A Brief Background Of Egyptian Mythology, Carol Pendleton Jan 1972

Osiris, God Of Ancient Egypt And A Brief Background Of Egyptian Mythology, Carol Pendleton

Undergraduate Honors Capstone Projects

In a country which has been subjected to so many inflows of various peoples, languages, and cultural patterns as has Egypt, one may expect to find a great diversity of deities and a complex and inconsistent theology. To differentiate the principal gods is the first step toward understanding the growth of the Egyptian religion. For in instances where polytheism can be traced back to its earliest stages we find that it usually has developed from a combination of monotheistic beliefs. It is improbable to suppose that a people would unite two gods, both of which belonged to them originally; there …

The Hydraulics Of Waste Stabilization Ponds, Gary Z. Watters Jan 1972

The Hydraulics Of Waste Stabilization Ponds, Gary Z. Watters

Reports

The treatment efficiency of waste stabilization ponds depends primarily on the biological factors of type of waste and organic loading. However, the biological activity in a pond is greatly influenced by the environmental conditions of temperature, wind, sunlight, and the hydraulic flow patterns. In the past little attention has been given to the hydraulic characteristics of waste stabilization ponds such as the gross flow patterns within stabilization ponds as affected by the shape of the pond or lagoon, the presence of dead spaces, and positioning of inlets and outlets and the degree of density stratification. These hydraulic flow characteristics will …

The Great Salt Lake And Utah's Water Resources , Utah Water Research Laboratory

Reports

Introduction: It is appropriate to introduce these proceedings with a brief description of this history and objectives of the American Water Resources Association (AWRA). Quoting from a recent information borchure published by the AWRA, it is a non-profit, scientific organization that was incorporated in the State of Illinous in March, 1964, with headquarters in Urbana, Illinois. A major factor in the establishment of the AWRA was the need for an organization to encourage and foster interdisciplinary communication between professionals of diverse backgrounds working on all aspects of water resources problems. The principal objectives of AWRA are stated briefly as follows: …

Model Study Of The Manifold To Be Used As A Component Of The Virginia Electric And Power Company, 1974 Extension Of Yorktown Power Station, Roland W. Jeppson, Calvin G. Clyde, Charles Kincaid

Reports

Introduction: This report describes the fabrication and laboratory testing of a 1/12 scale model of the 5 branch converging manifold to be installed as a component of the Virginia Electric and Power Company 1974 extension of the Yorktown power station. The design of the manifold (see Fig. 1) was supplied by Brown & Root, Inc. The geometry of Branch number 1 as shown on Fig. 1 was modified slightly from the original design after conferring with Browth & Root, Inc. in order to facilitate the fabrication of this branch of the model. In addition to the fabrication of the manifold …

Optimizing Resistance Coefficients For Large Bed Element Streams, D. E. Overton, Harl E. Judd, C. W. Johnson Jan 1972

Optimizing Resistance Coefficients For Large Bed Element Streams, D. E. Overton, Harl E. Judd, C. W. Johnson

Reports

This is a report of a comparison of Darcy resistance coefficients calculafed for previously reported laboratory data and those calculated for large bed element streams. Large bed element (LBE) streams exist frequently in nature where rocks derived from valley walls or from channels cutting through ancient glacial or fluvial deposits are moved only under conditions of extreme flood. The height of bed elements is a significant part of the mean depth of flow. The stream gradients are high and are quite stable for all but the highest flows.
