Mathematical Model For Water Quality In Streams Impacted By Point And Nonpoint Source Pollution, Michael E. Meadows Feb 1981

Mathematical Model For Water Quality In Streams Impacted By Point And Nonpoint Source Pollution, Michael E. Meadows

KWRRI Research Reports

Modeling the impacts of stormwater runoff on small streams, requires that the prediction model has the capability of simulating the behavior of the hydrologic and water quality components of the stream system. Development of such a model involves coupling the equations for pollutant transport during unsteady flow with the appropriate flood routing equations. The decision on which equations to choose requires a full understanding of the pollutant transport and hydrograph dispersion processes.

This research was undertaken to develop a rigorous theoretical evaluation of the pollutant transport and hydrograph dispersion processes during unsteady flow, and to recommend a suitable model for …

Forestry For Wildlife Habitat Improvement. Nebraska Cooperative Extension Service Ec 81-1747, Ec 80-1747, Frank A. Hershey, Howard L. Wiegers

School of Natural Resources: Faculty Publications

Wildlife cannot exist without food and protective cover. Natural and planted woodlands contribute significantly to these essentials. This circular describes habitat needs of wildlife, recommends forestry practices for habitat improvement, and gives examples of practices to improve habitat for pheasant, quail, and deer.

Variety, rather than uniformity of vegetation, benefits most wildlife species. Management which results in a diverse plant community with many stages of growth can increase the numbers and species of wildlife. Techniques which create improved conditions for woodland wildlife are fundamentally the same as those designed to grow good timber.

U.S. Army Corps Of Engineers Public Interest Review: An Evaluation Of Implementation Effectiveness, Sharon Kelberg Jan 1981

U.S. Army Corps Of Engineers Public Interest Review: An Evaluation Of Implementation Effectiveness, Sharon Kelberg

Marine Affairs Theses and Major Papers

The U.S. Army Corps of Engineers is authorized to permit or deny dredge and fill activities in the nation's coastal and wetland regions. Originally, responsible only for the maintenance of navigation, the Corps considered only navigational requirements in decisions to grant or deny permits. Now, however, the Corps must demonstrate, that the "public interest" is served as well. This study examines the scope of the public interest and attempts to evaluate the effectiveness of the program in a particularly controversial project. The initial phase provides evaluation criteria necessary to analyze the application of the public interest review. The second phase …

Beach Protection And Restoral Techniques And Their Application To The Rhode Island Coast, Dennis J. Stockwell Jan 1981

Beach Protection And Restoral Techniques And Their Application To The Rhode Island Coast, Dennis J. Stockwell

Marine Affairs Theses and Major Papers

It is the purpose of this paper to investigate the techniques and designs for beach protection today, and to show that efforts are largely motivated by the economic value involved. The primary cause of beach erosion will be addressed through a discussion of coastal processes. The construction and purposes of the common engineering structures will be explored along with examples of the materials presently being used. The east-coast beaches of Florida with their traditional recreational lure will provide good examples of large-scale efforts to protect high-cost waterfront investments. Rhode Island shoreline varies considerably along its length and is also chiefly …


Auctions As An Alternate Method Of Selling Fish In New England, Martin J. Vincent Jan 1981

Auctions As An Alternate Method Of Selling Fish In New England, Martin J. Vincent

Marine Affairs Theses and Major Papers

Selling fish at the landings stage by auction, as opposed to the current practices of selling to middlemen and through cooperatives, has been proposed by several authors. They suggest that fishermen would receive higher prices and that auction competition would improve fish quality.The aim of this study was to compile the rules and procedures of existing fish auctions, and to explore their effect on price formation. This would provide a basis for any who wished to determine the applicability of fish auctions in particular ports. While the findings are relevant to all fish auctions, special emphasis was placed on the …


Regional Planning On The South Shore: A Proposal For Improving Coastal Resources Management In Rhode Island, Thomas R. Ouellette Jan 1981

Regional Planning On The South Shore: A Proposal For Improving Coastal Resources Management In Rhode Island, Thomas R. Ouellette

Marine Affairs Theses and Major Papers

The Rhode Island coast is distinguished by estuaries and brackish ponds, sand dunes and barrier beaches, fertile agricultural soils and productive wildlife habitats. The state's coastal zone includes both the urban waterfront of Providence and the traditional rural environment of Washing and Newport Counties. Because of Rhode Island's small area (less than that of the average county in the United States: and high population density, the state's shoreline is in great demand by nearly all of its residents. Many are either dependent economically upon, or enjoy the recreational use of, the resources of the coast. However, the people of Rhode …

A High School Curriculum In Marine Environmental Issues: "The Sea - Use And Abuse" Part Ii, Martha J. Zimmerman

Marine Affairs Theses and Major Papers

To the Student: As we progress into the 1980's, you will become more aware of a number of marine related environmental issues. Many of these complex marine issues will be decided within the political sphere of our society. These are not isolated issues, but rather complicated ones which impact a wide section of our economic and social lives. The issues we are discussing include: land use (especially in the coastal zone), the city of facilities (e.g. sewer treatment plants, power plants, nuclear power plants), and the drilling for oil and gas and minerals on submerged and continental shelf areas. Port …

A High School Curriculum In Marine Environmental Issues: "The Sea - Use And Abuse" Part I, Martha J. Zimmerman

Marine Affairs Theses and Major Papers

To the Teacher: The materials presented and developed in this learning activity packet involve dynamic, complex, and persistent environmental issues concerning man's interaction with the oceans and the marine environment. As we progress into the 1980's, many decisions effecting the marine world will be made within the political sphere. These decisions will have wide-spreading impacts into the economic and social areas as well. Some consequences will be observed immediately, and others perhaps more serious, defiant of detection, and in some instances even hazardous, may have delayed results. The complex interrelationships of land and oceanic environments, the fragility of the marine …

Report No 41 - A Survey Method For Identifying Roadside Flora Suitable For Conservation In Western Australia, John K. Scott Jan 1981

Report No 41 - A Survey Method For Identifying Roadside Flora Suitable For Conservation In Western Australia, John K. Scott

Fisheries Research Reports

A survey method for identifying flora suitable for conservation alongside roads in south-western Australia was derived from an examination of characteristics of road verges. Two roads, from Midland to Toodyay and from Armadale to Bunbury, were examined. Width of verge, weed cover, soil disturbance, vegetation structure, presence of public utilities, evidence of fire and the type of adjoining land were measured at one mile (1.6 km) intervals on both sides of the road. Also recorded were aesthetic qualities such as stands of beautiful trees and sites of special interest, e.g. the presence of rare plants.

Three variables, percentage weed cover, …


Fisheries Report No 48 - The Western Rock Lobster Fishery 1976 - 1977, G. R. Morgan, E H. Barker Jan 1981

Fisheries Report No 48 - The Western Rock Lobster Fishery 1976 - 1977, G. R. Morgan, E H. Barker

Fisheries Research Reports

The fishery for the western rock lobster Panuldinus cygnus is one of the most important single fisheries in Australia and an important export earner for the State. The fishery is governed by a complex set of regulations which have been reviewed by Bowen (1971) and which are designed to limit the total effort to acceptable levels and to enforce a legal minimum size. It is thus important to constantly monitor the state of the fishery both to ensure that the effort is remaining within the accepted limits and that the regulations are adequately performing their function of maintaining reasonably stable …

Fisheries Report No 43 - A Pit Trap Survey Of Small Mammals, Lizards And Frogs On The Two Peoples Bay Nature Reserve, Stephen D. Hopper

Fisheries Research Reports

Ten pitlines were placed in open low woodlands near Moates Lake and in upland and coastal heathlands near Mount Gardner on Two Peoples Bay Nature Reserve during February 1980 and February 1981. The trapping program established that Common Dunnarts (Smitnthopsts murina) and Honey Possums (Tarstpes spencerae) were widespread in the reserve, and added three lizards and one frog to the list of vertebrates known to occur on the reserve.

Twenty mammals (15 native and 5 feral), four snakes, fifteen lizards, one tortoise and six frogs are now known on Iwo Peoples Bay Nature Reserve. They constitute a representative sample of …


Is Nature Our Birthright?, Nancy Heneson Jan 1981

Is Nature Our Birthright?, Nancy Heneson

Ecology Collection

It is of course impossible to escape the notion of self-interest in our relationship with nature. In fact, it is "unnatural," if one understands (and, one is forced to say nowadays, believes in) evolution. However, there is no real justification for either disguising this as stewardship or perverting it into dominionism. Every organism has an impact on the environment, and it is not only idealistic but biologically nonsensical to argue that we should leave everything alone. However, when decisions on policy are made which direct the future use of land, plants and animals, at least let the rationale not be …

Mountain Valley Planning Area, Rangeland Program Summary, United States Bureau Of Land Management

All U.S. Government Documents (Utah Regional Depository)

The Bureau of Land Management (BLM) intends to implement an improved rangeland program in the Mountain Valley Planning Area of central Utah. The program will be initiated during a five year period and will be followed by periodic updates. The program's benefits include improved watershed conditions through increased vegetation cover which will consequently reduce erosion. There will be an increase in the amount of rangeland in good condition and a decrease in the amount in poor condition. The rangeland's capacity ot sustain grazing by livestock and big game will also be increased. Wildlife habitat will be maintained or improved throughout …


Summary Utah/Western Colo, 1992 System Study, United States Department Of Energy Western Area Power Administration Jan 1981

Summary Utah/Western Colo, 1992 System Study, United States Department Of Energy Western Area Power Administration

All U.S. Government Documents (Utah Regional Depository)

The Utah/western Colorado area of the Rocky Mountain Region has adequate coal and water resources to support additional thermal generation plants beyond those already in service. Also within the region are several sites suitable for large-sized hydroelectric pumped-storage projects for purposes of supplying peaking power. The close proximity of these types of electric generating facilities is desirable in providing offpeak energy during the pumping cycle for the pumped-storage units. Considering that the potential capacity of each type of generation is in the 500 to 1,000 (two units) MW range per site and would require major extra-high-voltage (EHV) transmission developments, it …
