Grindstone Flat And Big Flat Exclosures - A 41-Year Record Of Changes In Clearcut Aspen Communities, United States Department Of Agriculture, Forest Service

Forestry

Deer browsing prevented aspen regeneration in both uncut stands and small 1/20-hectare clearcuts, even though nearby large burns regenerated successfully. Size of the clearcut or burned area may be critical in determining success of aspen regeneration; areas less than about 2 hectares in size may adversely concentrate deer use. Shrub production was less under deer use and forb production was less under cattle use than on protected areas. More apsen suckers were produced in uncut stands where cattle grazed than in stands protected from grazing, suggesting a possible relationship between sucker initiation and reduced competition from the herbaceous understory.

Water Supplies On Wheatbelt Farms : A General Picture, I A F Laing

Journal of the Department of Agriculture, Western Australia, Series 4

In good rainfall years, farm dams provide water fo more than 50 per cent of the total stock in the wheatbelt.

Other sources include ground water supplies and the piped Comprehensive Water Scheme.

The March 1970 census included questions on farm water supplies including how farmers coped in the 1969-70 drought.

Farm Dams In The Wheatbelt, I A F Laing

Journal of the Department of Agriculture, Western Australia, Series 4

Of the estimated 76 000 farm dams in the wheatbelt, about 8 per cent either leak or are salt affected. The remaining 70 000 dams are capable of holding water for livestock use and can be regarded as sercicable dams.

A great many of the serviceable dams are unreliable water supplies due to the combined effects of lack of runoff from catchments, shallow depth of storage and small size of storage in relation to expected demand from livestock and evaporation loss.

Design Standards For Farm Surface Water Supplies, J L. Frith

Journal of the Department of Agriculture, Western Australia, Series 4

Design is usually concerned with getting adequate return from limited recources. Farm dams which dry up represent dam failure. Less seriously, so too do dams which, although not drying out, never fill; they waste a recource.

Theses and Dissertations

A well-preserved fauna from the Tyler Formation was studied in cores from 34 wells drilled for oil in Billings, Golden Valley, McKenzie, Slope, and Stark Counties. Forty-four species of invertebrates, eleven form-species of conodonts, at least three types of fish, and at least four genera of plants· are present. Invertebrate species include 1 bryozoan, 15 brachiopods, 14 bivalves, 2 gastropods, 2 cephalopods, 2 annelids, 2 branchiopoda, at least 2 ostracodes, 2 malacostracans, 1 insect, and 1 echinoderm. Chordates include 1 "nonmarine" shark, at least 1 paleoniscoid fish, and 1 possible crossopterygian fish. A new genus and species of eocarid malacostracan …

Variation Among Populations Of The Troglobitic Amphipod Crustacean Crangonyx Antennatus Packard Living In Different Habitats I. Morphology, Gary W. Dickson

International Journal of Speleology

Populations of the troglobitic (i.e., obligatory cavernicole) amphipod Crangonyx antennatus living in two distinct aquatic habitats were examined for possible morphological variation. Collections were made seasonally for one year in six Lee Co., Virginia caves, three with mud-bottom pools and three with small gravel-bottom streams. Environmental parameters thought to influence population variation were recorded for each of the six caves. Body length of mature amphipods was found to be greater in the mud-bottom pool habitats, whereas stream amphipods possessed more first antennal segments per unit body length. Variation was also observed in integument coloration; stream amphipods were characterized by a …

The Glacial Geology Of Mckenzie County, North Dakota, Clark Fulton

Theses and Dissertations

Fourteen lithostratigraphic units composed of windblown, glacial, lake, slopewash, and stream sediment were distinguished in McKenzie County, The units were mapped using aerial photographs, topographic maps, and soil maps combi11ed with field e:xaminations of sediment outcrops. Eight of the units have been formally named and described in earlier studies. Four of them, however, have not been a"~ previously named and formally described .a.nu assigned names in this study. Two other units are described, but because of their limited exposure, are not assigned a formal lithostratlgraphic name. The oldest sediment exposed in the county was deposited during the Paleocene and the …

Hydrodynamic Separation Of Solids From Solid-Liquid Mixtures, Harry J. Sterling Jr., Don J. Wood

KWRRI Research Reports

Several schemes for separating solid pollutants from water flowing in a closed conduit were examined. Separation based on the momentum differential between the solids and liquids and the centrifugal movement of a conveying liquid were both examined under turbulent flow conditions. The study indicated these processes to have limited applications, primarily due to the difficulties in withdrawing a significant fraction of separated flow and the deleterious effects of turbulent mixing. However, utilization of the differential momentum of solid particles and water when flowing laminarly through a pipe was found to be a viable separation scheme. Significant experimental separations (greater than …

The Geology Of The Caballo Peak Quadrangle, Sierra County, New Mexico, James Trimble Mason

Earth and Planetary Sciences ETDs

The Caballo uplift, along the east side of the southern end of the Rio Grande depression, is comprised of rocks which range in age from Precambrian to Recent. The northern Caballo Mountains do not contain rocks of Silurian, Devonian, Mississippian, Triassic, Jurassic, or Lower Cretaceous ages. The Precambrian rocks consist mainly of granite which encloses small rounded bodies (possibly roof pendants) of biotite-hornblende gneiss and schist, granitic gneiss, and metasediments. The Lower Paleozoic is comprised of the Cambro-Ordovician Bliss Formation, the Ordovician El Paso Group, and the Ordovician Montoya Group. These marine sediments are overlain unconformably by the Pennsylvanian Magdalena …

Nitrogen Fertilization Studies In Dryland Winter Wheat And Potential Nitrogen Losses From The Soil At The Blue Creek Experimental Station In Northern Utah, Subhawat Intalap

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study compared the effects of nitrogen sources on the available inorganic soil nitrogen, nitrogen movement, nitrogen losses, and wheat yields when nitrogen fertilizers were applied to soil planted to dryland winter wheat at the Blue Creek Experimental Station in northern Utah.

In the fall 1973 soil samplings, the fertilizers producing the largest mineral nitrogen contents in the 0-30 cm soil depths were ammonium nitrate >ammonium sulfate > S-coated urea, when they were broadcast at the practical rate of 56 kg N/ha. There was no increase in the mineral nitrogen at the dee per depths in the fall or at any …

An Evaluation Of The Effects Of Dredging Within The Arkansas River Navigation System, Volume Iv - The Effects Upon The Benthic Associations, Louise Russert Kraemer

Arkansas Water Resources Center Technical Reports

The huge and increasing volume of dredged materials being moved in and from the bottoms of waterways of the U.S. is probably well known to the reader. Lee and Plumb (1974) distinguish between the 2 forms of dredging: (1) mining the bottom sediments (as in shell dredging), and (2) developing and maintaining navigable waterways. They indicate some 380,000,000 cubic yards are dredged annually in this country; maintenance dredging accounting for about 80,000,000 cy, and new construction for about 300,000,000 cy.* These figures (based on 5 yr. averages) do not include dredging by private companies. Smith (1975) comments: "With federal dredging …

The Arkansas River extends for 1,450 miles from the eastern slopes of the Rocky Mountains in Colorado, southeasterly through Kansas, Oklahoma, and Arkansas, where it enters the Mississippi River in Desha County. The 448 mile navigation channel which was constructed on the lower portion of this river includes portions of two of its major tributaries, the Verdigris River in Oklahoma and the lower White River in Arkansas. The Arkansas portion of this navigation system consists of three different segments: (1) the lower White River, from its confluence with the Mississippi River to 10 miles upstream, (2) the Arkansas Post Canal, …
