Dam Site Selection In The North-Eastern Wheatbelt, J L. Frith

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

Western Australia's wheatbelt farm dams are dug three to eight metres deep and are generally sited in soils which either are inherently impermeable or can be made so during construction.

In the eastern and north-eastern wheatbelt, however, only a small proportion of the soils meets these criteria. Dam site selection in these areas therefore depends on a good knowledge ofwhich soils aresuitable and on our being able to locate them efficiently by using surface indications such as surface soil, natural vegetation or topographic features.

Drought Proofing The Farm : Case Studies, J L. Frith

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

For many years, Western Australia's north-eastern wheatbelthas suffered chronic shortages of water for stock and domestic use. The area's averageannual rainfall is generally low - less than 300 millimetres - and droughts in the 1970s caused futher problems. manydams in the area leak or have inadequate catchmentsand groundwater is scarce ormofmpoor quality.

In March 982, the Western Australian Government provided $100 000 for the Department of agriculture to demonstrate the potential of establishing permanent, drought-proof water supplies on farms in the north-eastern wheatbelt. The methods were to use exixting techniques to build dams and catchments. In a year of low …

Sandplain Hardpan : A Different Dam Construction Material, A F. Mccrea

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

Before 1980, the Department of Agriculture did not believe that suitable farm dam materials could be found in light land soils. However Beacon earthmoving contractor, V> J> Pavlinovich, has demonstrated that where suitable cemented subsoils or 'hardpan' existed, a succcessful dam site could be found.

This material should not be confused with compaction or traffic hardpans ehich are dense layers of soil found near the surface. Traffic hardpans result from compaction of soil materials with the passage of vehicles and farm machinery. Rather, the hardpan referred to here is a natural subsoil layer that has been cemented by silica and …

Acidification Sources In Red Alder And Douglas-Fir Soils -- Importance Of Nitrification, H. Van Miegroet, D. W. Cole

Watershed Sciences Faculty Publications

Precipitation, throughfall, forest floor, and soil leachate samples were monitored continuously in 1981 and 1982 in a N-poor Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] forest and a red alder (Alnus rubra Bong.) forest growing adjacently on a glacial soil in western Washington. The purpose of the study was to quantify the relative importance of atmospheric vs. natural sources of H+ input to forest soil acidification, and to determine the role of N transformation processes in the overall H+ balance of soils with different N status. Rainwater samples had an avg pH of 4.7 and annual H+ deposition via precipitation averaged 320 …

Delineation Of Landslide, Flash Flood, And Debris Flow Hazards In Utah, David S. Bowles

Reports

During 1982, 1983, and 1984, abnormally wet conditions in Utah triggered flash floods, landslides, and debris flows. Pore pressures built in hillside soils below melting snows and during prolonged periods of rainfall until the mass suddenly gave way, sometimes as a landslide and other times as a non-Newtonian debris flow that moved rapidly long distances down mountain slopes until finally stiffened by moisture loss or velocity loss because of flatter gradients. Also, runoff from heavy rainfall bursts picked up weathered and other loose material that accumulated on land surfaces over long dry periods . The sediment laden waters flowed out …

Evaluation Of Structure And Growth Of Bluegills And Black Bullheads Stocked With Largemouth Bass In South Dakota Farm Ponds, Charles E. Morris

Electronic Theses and Dissertations

A two-year study estimated standing stock, growth, condition, survival rates, and population structure of bluegills (Lepomis macrochirus) and black bullheads (Ictalurus melas) stocked in South Dakota farm ponds with largemouth bass (Micropterus salmoides). Bluegills and black bullheads reproduced during the second growing seasons and by the end of the study three year-classes of fishes were present in most ponds. Mean back-calculated bluegill total lengths at annuli 1-3 were 58, 125, and 153 mm, respectively. Mean back-calculated black bullhead total lengths at annuli 1-3 were 82, 182, and 240 mm, respectively. A significant north vs south difference (P≤0.05) in third-year bullhead …

Lungworm Infections, Reproduction And Summer Habitat Use Of Bighorn Sheep In Custer State Park, South Dakota, Gary C. Brundige

Electronic Theses and Dissertations

Bighorn sheep (Ovis canadensis) were once indigenous to the Black Hills and Badlands of South Dakota. When European settlers moved into this region during the late 1800' s, market hunting, loss of habitat, and introduction of animal diseases and parasites caused the subspecies of the region, the Audubon's bighorn sheep (O. c. auduboni), to become extinct by 1916 (Buechner 1960). To reestablish bighorn sheep in the Black Hills, 8 Rocky Mountain bighorn sheep (O. c. canadensis) were introduced into the former range of the Audubon's sheep in 1922. Finding the habitat to be very suitable, this small population increased to …

Distribution, Temperature Selection, And Gonadal Development Of Fishes In A Power Plant Cooling Reservoir, Henry R. Maddux

Electronic Theses and Dissertations

The distribution, temperature selection, and gonadal development of fishes in the Big Stone Power Plant cooling reservoir were examined from July 1982 through July 1983. A total of 46.8% of the fishes captured during this study were from the discharge area, while 31.8% and 21.4% of the fish occurred in the mixing and intake areas, respectively. The mean water temperature occupied by common carp (Cyprinus carpio) ranged from 7.5 C in February to 31.2 C in August. Black bullheads (Ictalurus melas) were generally benthic and captured in the cooler water. The mean water temperature occupied by black bullheads ranged from …

Water Supplies : Dams And Roaded Catchments, W J. Burdass, T. R. Negus, A. L. Prout, I. A. F. Laing

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

Western Australia's Upper and Lower Great Southern statistical areas include most of the broad-scale agricultural land south of a line from Perth to Hyden. Much of the area is well-developed and carries 13.4 million sheep, 203 00 cattle and 95 000 pigs, almost half the State's livestock.

There are few natural rivers and lakes to water livestock in summer and much of the bore water is salty. On-farm waterr conservation, therefore, consits mainly of excavated earth tanks (dams) which are filled by surface runoff or shallow seepage. In the drier areas and in the sandplain roaded catchments have neen built …

Northern Wheatbelt Water Supply Study, I A F Laing, R. M. Pridham

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

Department of Agriculture surveys have shown that many farms in Western australia's northern wheatbelt have inadequate water supplies. More than 80 per cent of all farms in that area depend soley on groundwater for watering livestock, a much higher percentage than for most other farming areas. Because groundwater salinities have increased in recent years, concern is held for the long-term future of this recource.

In contrast to more southern agricultural areas, farm dams in the northern wheatbelt are relatively uncommon. Only 30 per cent of the existing dams in the northern wheatbelt constitute effective water supplies. More than half of …

Increasing Groundwater Salinity In The Northern Wheatbelt, R J. Mcgowan

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

Every farmer in western Australia's northern wheatbelt will know of a groundwater supply, be it bore, well or soak. that has become increasingly saline. The groundwater may have become more saline over a period of 15 years or more, or have been noticed only recently. Inevitably, the bore will lie within an area cleared for agriculture. This increase in groundwater salinity may be associated with soil salinisation. Although researchers have some understanding of the processes causing salinisation of groundwater in the wheatbelt and the extent of the problem, little is known about the rates of salinisation and groundwater rise. A …

Fundy Tidal Power: A Need To Reassess The Environmental Framework Protecting The Transboundary Environment, Robert W. Rudolph

Marine Affairs Theses and Major Papers

The concept of harnessing the tides for energy is receiving renewed attention in the maritime provinces of Canada and northeastern United States where a scarcity of indigenous energy resources exists. While proposals for several small tidal power facilities are being considered in Maine, in Canada, Nova Scotia officials are moving ahead with plans for a major tidal power project (4,028 MW) in the Minas Basin in the Bay of Fundy. The vast majority of the power generated from this facility is expected to be exported to the New York and New England areas which have a greater energy demand that …

Soils And The Location Of Cacao Orchards At A Maya Site In Western Belize, Daniel R. Muhs, Robert R. Kautz, J. Jefferson Mackinnon

United States Geological Survey: Staff Publications

Cacao was one of the most important crops of the lowland Maya. Ethnohistoric sources document that the Postclassic-Colonial Period Maya settlement of Tipu in western Belize was an important cacao-growing center, yet evidence of where the cacao was grown is not apparent. We analysed the suitability of floodplain, terrace, and bedrock soils for cacao cultivation. Our results indicate that the soils most likely to have been used for cacao growth were those on the modem floodplain of the Macal River, based on their suitable physical and chemical properties. In addition, buried stone walls of Late Classic or Postclassic age that …

Groundwater Management By Linear Programming, Seungho Song

Civil & Environmental Engineering Theses & Dissertations

Three hydraulic optimization models are developed. These models combine the finite difference equations of two-dimensional groundwater flow in composite aquifers with various linear programming techniques. The hydraulic submodel employed in these hydraulic optimization models is so versatile that it accounts for time varying pumpage, leaky artesian conditions, a variety of boundary conditions, induced infiltrations from streams or rivers, and conversion from artesian to water table conditions. The objective of submodel 1 is to maximize the total hydraulic head from pumping wells at the end of a study period. The objective of submodel 2 is the same as submodel 1, but …

Precedings Of Arkansas Lakes Symposium Limnological Studies Of Lake Chicot, Arkansas, Joe F. Nix, Frank R. Schiebe

Arkansas Water Resources Center Technical Reports

Lake Chicot is an oxbow lake that was created more than 600 years ago by the meandering of the Mississippi River. It is located in Chicot county in southeastern Arkansas adjacent to the present Mississippi River. As the largest natural lake in Arkansas it earned an early reputation for its good fishing and recreational value. Development of a levee system forced the enlargement of the lakes watershed to its present 350 square miles. Initially this alteration affected only the volume flow through the lake, drastically reducing the water residence time. Because the watershed was located in one of the most …

Discharge And Travel Time Determinations In The Royal Spring Groundwater Basin, Kentucky, John Thrailkill, Douglas R. Gouzie

KWRRI Research Reports

Groundwater flow in many karst regions, including the Inner Bluegrass Karst Region of central Kentucky in which the study area was located, is unlike groundwater flow in granular aquifers. At least the major flows are turbulent and often with a free surface in large conduits, and applying concepts based on Darcy's Law to describe and model these flows is inappropriate. Parameters such as linear velocity, channel geometry, and conveyance used to describe surface streamflows are more applicable, and the primary objective of the project was to estimate these in a groundwater basin using the travel time of dye slugs and …

The FLPMA conference will bring together a distinguished group of experts to review the law itself, to consider the effectiveness with which it has been implemented, and to discuss the key issues which have arisen under its implementation.

Comments On The Geologic History Of The Ogallala Formation In The Southern Panhandle Of Nebraska, Robert F. Diffendal Jr.

School of Natural Resources: Faculty Publications

The southern Panhandle of Nebraska and the adjoining parts of southeastern Wyoming and northeastern Colorado are unusual places to examine the geologic history of the Ogallala Formation because they are much closer to the source areas of much of the sediment which makes up the unit than are other sites along the Ogallala outcrop belt. This study in Nebraska combined with results of earlier work there, in southeastern Wyoming, and ; northeastern Colorado, outlines the complex cut and fill history of the Ogallala close to Rocky Mountain source areas.

Parts of the Ogallala consist of fills of sand and gravel, …

U. S. Arctic Oil: A Perspective, William T. Decamp

Marine Affairs Theses and Major Papers

The United States Arctic, for the purposes of this study, encompasses the seabed and subsoil under the resource jurisdiction of the United States, including the Bering Sea offshore, and the Hope Basin, Chukchi (Barrow Arch) and Beaufort (Diapir Field) Seas, and land territory north of the Brooks Range onshore. Although U.S. credibility with its Arctic allies would be enhanced by its becoming a party to the Law of the Sea Convention, this remote possibility is not a prerequisite for a successful U.S. Arctic Policy. It is more important that U.S. policy goals are perceived among its Arctic allies as being …
