Federal Lands, Laws and Policies and the Development of Natural Resources: A Short Course (Summer Conference, July 28-August 1)
Even before the [Natural Resources Law] Center was established [in the fall of 1981], the [University of Colorado] School of Law was organizing annual natural resources law summer short courses. To date four programs have been presented:
- July 1980: "Federal Lands, Laws and Policies and the Development of Natural Resources"
- June 1981: "Water Resources Allocation: Laws and Emerging Issues"
- June 1982: "New Sources of Water for Energy Development and Growth: lnterbasin Transfers"
- June 1983: "Groundwater: Allocation, Development and Pollution"
(Reprinted from Resource Law Notes, no. 1, Jan. 1984, at 1.)

Evaluation Of Impacts Associated With Reregulation Of Water Levels In Lake Mohave, Larry J. Paulson, John R. Baker, U.S. Water And Power Resources Service
Evaluation Of Impacts Associated With Reregulation Of Water Levels In Lake Mohave, Larry J. Paulson, John R. Baker, U.S. Water And Power Resources Service
Publications (WR)
The U.S. Water and Power Resources Service is considering reregulating Lake Mohave water levels to increase the net power benefit from Hoover Dam. Reregulation will not increase the generation capacity of the Hoover powerplant but it will enable the plant operation to be increased when the energy has greater monetary value. Energy generated at different times of the year has different market value, the highest being in January-March and July- September. By generating more power during these periods more net monetary benefit can be derived from Hoover Dam. The total volume of water released from Hoover Dam over an annual …
Wind Drag On Burley Tobacco Plants, James H. Casada, Linus R. Walton, Larry G. Wells
Wind Drag On Burley Tobacco Plants, James H. Casada, Linus R. Walton, Larry G. Wells
Biosystems and Agricultural Engineering Faculty Publications
Drag coefficient and center of resistance to wind forces were determined for four varieties of burley tobacco at three stages of growth and using wind velocities ranging from about 3 to 17 m/s. Drag coefficients determined ranged from about 0.024 at the highest velocity to about 0.081 at the lowest velocity. Stage of growth and wind velocity had significant effects on drag coefficient. Variety did not have a significant effect on drag coefficient. Mean center of resistance varied from 42.3 percent of the distance from bottom leaf to top leaf at the early stage of growth to 71.2 percent at …

Dickey-Lincoln Mitigation Plans Under Review By Engineer Board, Engineering Board, New England Division
Dickey-Lincoln School Lakes Project
Plans to mitigate wildlife habitat and fisheries losses resulting from construction of the proposed 830-megawatt Dickey-Lincoln School hydroelectric project have been forwarded for Independent review by the Board of Engineers for Rivers and Harbors, an arm of the U.S. Army Corps of Engineers.

Dickey-Lincoln School Lakes Project Environmental Impact Statement: Appendix K: Fish & Wildlife Mitigation Plan & Impacts (Revised), New England Division, United States Army Engineer Division
Dickey-Lincoln School Lakes Project
The proposed plan is comprised of three major segments: terrestrial, fisheries and endangered species. Each segment is essentially a self-contained unit. All costs for the three segments including land acquisition, operation and maintenance and capital equipment, are to be charged to the project and allocated to the project purposes of hydroelectric generation and flood control.

Dickey-Lincoln School Lakes Project
The Dickey Lincoln School Lakes Project is a proposed multipurpose project located on the upper reaches of the St. John River in Aroostook County, Maine. Development would consist of two dams with associated reservoirs and hydroelectric generating facilities, five dikes and transmission lines. A more detailed description of the proposed project and its associated impacts is contained within the Revised Draft Environmental Impact Statement for the proposed project.
The Influence Of Harvesting Strategies And Economic Constraints On The Feasibility Of Farm Grain Drying And Storage Facilities, Otto J. Loewer Jr., Thomas C. Bridges, G. M. White, Douglas G. Overhults

The economic return to on-the-farm grain drying and storage facilities is influenced by many factors including harvesting strategies, facility management, market conditions, energy considerations, and facility design. This study evaluates the influence of these factors on expected net return.
Ground Driven Powered Tillage, Larry G. Wells, E. M. Smith, D. E. Hammett, H. J. Thompson Jr.
Ground Driven Powered Tillage, Larry G. Wells, E. M. Smith, D. E. Hammett, H. J. Thompson Jr.
Biosystems and Agricultural Engineering Faculty Publications
A ground driven powered tillage device is described which utilizes a passive rolling coulter propelled through the soil by a prime mover. The reaction torque imparted by the soil to the coulter is delivered via a torque transfer unit to a powered tillage blade. The tillage blade rotates counter to the direction of the passive rolling coulter and prepares a tilled furrow of some predetermined depth for seed placement and coverage.
Analysis is presented in which the torque developed by a passive rolling coulter engaging the soil is predicted. A relationship is presented for determining the velocity ratio between the …

Analysis And Testing Of Powered Tillage Blades, Larry G. Wells, E. M. Smith, D. E. Hammett

Fundamental design considerations for powered rotary tillage blades are presented and discussed. The relationship between blade angular velocity and the geometric dimensions of cutting edges is specified for tillage blades rotating counter to the direction of travel and assuming a typical forward speed for tillage.
Analyses showed that a powered blade rotated opposite to the direction of travel can be operated at relatively lower angular velocities than can one rotated in the direction of travel to achieve equivalent blade velocity and acceleration relative to the soil. Furthermore, a blade rotated opposite to the direction of travel requires relatively lower power …

The computer model CATCH (Computer Analysis of Tobacco Cutting and Housing) was developed to provide the individual tobacco producer with management information concerning alternative methods of harvesting burley tobacco. CATCH utilizes specific producer in-puts to analyze 24 alternative burley production systems and presents up to four economic rankings containing costs, equipment and labor for each system. The economic rankings aid the producer in decision making with regard to his own operation.
Influence Of Dredging And High Discharge On The Ecology Of Black Canyon, Larry J. Paulson, Theron G. Miller, John R. Baker, U.S. Water And Power Resources Service
Influence Of Dredging And High Discharge On The Ecology Of Black Canyon, Larry J. Paulson, Theron G. Miller, John R. Baker, U.S. Water And Power Resources Service
Publications (WR)
The Water and Power Resources Service is considering dredging in Black Canyon to create a larger forebay to accommodate higher peak discharges and reverse flows for proposed modifications to Hoover Dam.
The Black Canyon area from Hoover Dam to Willow Beach supports a heavily utilized trout fishery and is important habitat for the razorback sucker (Xyrauchen texanus) and possibly bonytail chub (Gila elegans).
The Water and Power Resources Service initiated this investigation to determine what effect dredging and higher peak-discharges would have on the ecology of Black Canyon.

A rather unique systems analysis approach has been made to simulate the utilization of dry matter by ruminant animals, and the natural breeding and reproduction process within a herd. Physiological factors occurring over time and the time related effects of these factors are simulated.
Petroleum Degradation By Naturally Occurring Populations Of Marine Bacteria From Middle Atlantic Outer Continental Shelf Waters, Alexander Maccubbin
Petroleum Degradation By Naturally Occurring Populations Of Marine Bacteria From Middle Atlantic Outer Continental Shelf Waters, Alexander Maccubbin
Dissertations, Theses, and Masters Projects
Bacterial populations indigenous to surface (1 m) waters of the Middle Atlantic Outer Continental Shelf were sampled at seasonal intervals to determine the abundance and distribution of petroleum-degrading (HC) and "total" heterotrophic (HET) bacteria. Simultaneously, unweathered South Louisiana crude oil (SLCO) was added to aliquots of surface water samples to evaluate rates and patterns of degradation of hydrocarbon. Degradation was studied using selected nutrient and temperature regimes in both closed flask and prototype "open" or continuous dilution systems. HET bacterial levels generally decreased with distance from land (x inshore = 6 x 10('4) MPN/ml to x offshore = 6 x …
