Extreme Evapotranspiration By Irrigated Alfalfa: A Consequence Of The 1976 Midwestern Drought, Norman J. Rosenberg, Shashi B. Verma

Drought Mitigation Center: Faculty Publications

The rate of evapotranspiration by irrigated alfalfa at Mead, NE (41°09'Nj 96°30'W, elevation 354 m) reached record levels in 1976. Evapotranspiration was measured with precision weighing lysimeters in a field 1.9 ha in size. Evapotranspiration ranged during the growing season from 4.75 to 14.22 mm day^-l and exceeded 10 mm day^-I on one-third of the days studied. On each day of study the ratio of latent heat flux density (LE) to the sum of the net radiation and soil heat flux densities (Rn+S) was such that LE/ (Rn+S) > 1, indicating the occurrence of significant …

Local And Regional Components Of Sensible Heat Advection, Thomas W. Brakke, Shashi B. Verma, Norman J. Rosenberg

School of Natural Resources: Faculty Publications

Detailed knowledge of the advection of sensible heat is necessary to understand the energy balance of the evaporating surface in many parts of the world. Sensible hear advection can result from regional and/or local sources. The local and regional components of sensible heat advection (Aloc and Areg, respectively) are identified and their magnitudes in a semi-arid to sub-humid zone are established in the work reported here. Measurements of dry- and wet-bulb air temperature, wind speed and net radiation were made above an irrigated alfalfa field with relatively dry surrounding upwind at Mead, NE. A modified Bowen ratio-energy balance method which …

Guidelines For Zooplankton Sampling In Quantitative Baseline And Monitoring Programs, Fred Jacobs, George C. Grant

Reports

Methods applicable to zooplankton sampling and analysis in quantitative baseline and monitoring surveys are evaluated and summarized. Specific recommendations by managers must take into account characteristics of the water mass under investigation, the abundance of contained zooplankton and phytoplankton populations and the objectives of the study. Realistic planning and development must also consider available monetary and manpower resources.

Critical Evaluation Of The Pulsed-Current Resistance Meter For Detection Of Decay In Wood, Douglas D. Piirto, W. Wayne Wilcox

Natural Resources Management and Environmental Sciences

An evaluation of a pulsed-current resistance meter ("Shigometer®", Model No. 7950) for facilitating detection of decay was performed on wood blocks of giant sequoia heartwood and of white fir sapwood. As decay progressed over a 12-week incubation period, a trend of lower meter readings was obtained, confirming reported field measurements of other workers. Variability in meter readings in situations where the range in resistance readings between sound and decayed wood is narrow (e.g., giant sequoia heartwood) and apparent inability of the meter to make readings necessary to diagnose decay at MCs common to wood in service without ground or water …

Dickey-Lincoln School Lakes, Maine, Hydro-Power Decision, October 27, 1978, James B. Longley

Dickey-Lincoln School Lakes Project

The Dickey-Lincoln School Project would consist of two earthfill structures designed to produce peaking and modest intermediate load power from the St. John River The larger of the two dams, the Dickey Dam, would be located immediately above the confluence of the Allagash and St. John Rivers. The Lincoln School Dam would also be located on the Upper St. John River, eleven miles downstream from the Dickey Dam. The Dickey Dam would have a total length of 10,600 feet and a maximum height of 335 feet. The Lincoln School Dam is considerably smaller and would be 1,600 feet long and …

Dickey-Lincoln School Lakes Project

The U.S. Departments of the Interior and Energy have conducted system planning, location, and environmental studies for the trans-mission facilities required for the Dickey-Lincoln School Hydroelectric Project. These studies of many alternate routes have resulted in iden-tification of a proposed transmission line route, and an environmental impact statement, as required by the National Environmental Policy Act of 1969. This report, documenting an early phase of the overall studies, was first published by the Department of the Interior in February 1977. It is being republished as Appendix A to the DOE Environmental Impact Statement for the project.

Dickey-Lincoln School Lakes Project

This report identifies alternative corridors of land within which transmission lines could be routed and details various impacts on the environment which would be associated with introduction of transmission facilities. Many alternative corridor locations were identified (see Figure 1-1). Identification of these alternative transmission corridors was a complex process, since the number of potential corridors capable of connecting the various substations was myriad; the 'least desirable' potential corridors, i.e., those where transmission facilities might have entailed severest impacts on the environment, had to be eliminated from consideration before alternative corridors could be delineated. Identified alternative corridor locations were subsequently evaluated …

Producing 20-Month Old Beef Steers Off Annual Pasture, K D. Greathead, D. J. Barker, W. J. Ryan

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

A recent Mt Barker experiment compared two systems of fodder conservation with continuous grazing, using two types of steers, at three stocking rates. Year-round performance, carcass composition, and resulting costs and returns per hectare were assessed.

Production per hectare was greatest from crossbred steers at the intermediate stocking rate with either type of fodder conservation.

An Evaluation Of The Effects Of Dredging Within The Arkansas River Navigation System - Volume I - Introduction, Summary And Conclusions, And Recommendations, Arkansas Water Resources Research Center

Technical Reports

The foundation for the development of the Arkansas River was laid with the authorization of many upstream reservoirs in the comprehensive River and Harbor Act of 1946 signed by President Truman. Subsequent authorizations were forthcoming and work began on many of the bank stabilization facilities in 1950 and on the major structures in 1957. The current McClellan-Kerr Arkansas River Navigation System was substantially completed in 1972. The authorized multiple-purpose plan for the Arkansas River and tributaries provided for the construction of coordinated developments in the interests of navigation, hydroelectric power, flood control, bank stabilization, and related benefits including recreation and …

Turbulent Exchange Coefficients For Sensible Heat And Water Vapor Under Advective Conditions, Shashi Verma, Norman J. Rosenberg, Blaine L. Blad

School of Natural Resources: Faculty Publications

Results are presented of micrometeorological measurements made over alfalfa and soybeans under conditions of sensible heat advection at Mead, Neb. The sensible heat advection phenomenon reported here is of a regional rather than a local nature. The exchange coefficient for sensible heat (Kh) is found to be generally greater than the exchange coefficient for water vapor (Kw). This result contradicts the usaul assumption of equality of Kh and Kw under nonadvection (lapse or unstable) conditions when the net transfer of both sensible heat and water vapor are away from the earth's surface. Under advective conditions, however, heat and water vapor …
