An Economic Evaluation Of The Salinity Impacts From Energy Development: The Case Of The Upper Colorado River Basin, Rangesan Narayanan, Sumol Padungchai, A. Bruce Bishop Jan 1979

An Economic Evaluation Of The Salinity Impacts From Energy Development: The Case Of The Upper Colorado River Basin, Rangesan Narayanan, Sumol Padungchai, A. Bruce Bishop

Reports

To analyze the effect of potential energy development on water allocation and water quality in the Upper Colorado River Basin, a linear programming model is formulated. Using the model, changes in salinity are predicted. Further, least-cost strategies to maintain the established numeric salinity criteria through both structural and nonstructural alternatives are developed. The effectiveness of alternative control measures are examined within given institutional constraints. Based on cost-benefit analysis, optimal salinity levels over time are proposed. The economic feasibility of presently planned strucutral measures to reduce salinity is investigated and contrasted with nonstructural alternatives.

Spatial Context And Temporal Aspects Of The Sensitive Area Concept In Ontario, Barbara Elizabeth Anderson

Theses and Dissertations (Comprehensive)

The term “sensitive area” is a product of planning initiatives which have developed within the province of Ontario since the early nineteen seventies. As there are a number of closely related terms utilized the sensitive areas concept generally is defined as the creation of a reserve or the removal of land from unfettered commercial development or intense human use. The concept has been associated with a broad range of environmental concerns such as, the protection of wildlife habitat, maintenance of ecological function, retention of scenic areas and preservation of historic sites. Similar initiatives across North America are surveyed and the …

Modelling The Influence Of Eutrophication On The Coldwater Fishery Habitat Of Lake Mcconaughy, A "Two-Story" Reservoir, Melvin W. Taylor

Nebraska Game and Parks Commission: Publications

The lifespan of the existing coldwater habitat in Lake McConaughy is unknown, To promulgate effective management and regulatory strategies, a method of predicting this lifespan was needed, Ideally, this procedure should also provide potential management philosophies that would retard eutrophication, The LAKSCI computerized simulation model of Systems Control, Inc, was modified to assist in solving this problem, Data for model input were collected from August 1976 to August 1978. When calibrated the model proved satisfactory for predicting water level and temperatures, but unsatisfactory in prediction of water chemistry without additional data and refinement,

Potential Use Of Hydroelectric Facilities For Manipulating The Fertility Of Lake Mead, Larry J. Paulson, John R. Baker, James E. Deacon Jan 1979

Potential Use Of Hydroelectric Facilities For Manipulating The Fertility Of Lake Mead, Larry J. Paulson, John R. Baker, James E. Deacon

Publications (WR)

Analysis of historical nutrient data for Lake Mead indicates that the fertility of the reservoir has decreased which may be the cause for a corresponding decline in the largemouth bass population. However, it appears that fertility can be manipulated by altering the operation of the dam. The depletion of nutrients in the euphotic zone by phytoplankton and subsequent accumulation in the hypolimnion during summer and fall provide a natural nutrient gradient from which water of varying fertility can be drawn for discharge. This combined with alterations in the depth or seasonal pattern of discharge can possibly be used to enhance …

Changes In The Forest Composition In The Great Lakes St. Lawrence Forest Region Of Ontario And The Resultant Outbreaks Of The Spruce Budworm Choristoneura Fumiferana (Clem.), John F. Bowen

Theses and Dissertations (Comprehensive)

The spruce budworm Choristoneura fumiferana Clem. is the foremost forest pest in Canada. The species is endemic to eastern North America. Since the turn of the century the insect has become a major problem in the “Great Lakes St. Lawrence Forest Region” of Ontario, an area where prior to recent times the insect did not occur in damaging numbers.

Analysis of the life cycle of the insect reveals that the only limiting factor capable of controlling outbreaks is a lack of food. The required tree species is balsam fir Abies balsama (L.) Mill. The forests of Ontario have been altered …
