The Rush Creek Structure, Garden County, Nebraska, Robert F. Diffendal Jr. Apr 1978

The Rush Creek Structure, Garden County, Nebraska, Robert F. Diffendal Jr.

School of Natural Resources: Faculty Publications

Detailed field mapping of surface outcrops in southern Garden County, Nebraska, has revealed a drop of 200 feet in three miles in the elevation of the contact between the Ogallala and pre-Ogallala (probably Brule) Formations exposed on the east side of Rush Creek. Beds of silt, sand, siltstone, and volcanic ash in the are a locally dip to the northwest at angles of up to 8½°. The contact between the two formations cannot be seen on the west side of Rush Creek but beds in the Ogallala Formation there dip to the north and northeast. The unusually long valley of …


Extreme Evapotranspiration By Irrigated Alfalfa: A Consequence Of The 1976 Midwestern Drought, Norman J. Rosenberg, Shashi B. Verma Feb 1978

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 …

A Recent Decline In Available Moisture In Northern Victoria Land, Antarctia, Paul Andrew Mayewski, John W. Attig Jr

Earth Science Faculty Scholarship

Evidence from two areas in northern Victoria Land, Antarctica demonstrate that available moisture has been declining since at least I 265 B.P. The cause is not known.


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 Jan 1978

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 …


Deep Drainage As A Method Of Treating Saltland, Eric Bettenay Jan 1978

Deep Drainage As A Method Of Treating Saltland, Eric Bettenay

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

In some situations, deep drainage may be warranted to return salt-affected land to full production.

This method is being investigated at CSIRO's Yalanbee Experiment Station.


Final Report Buffalo National River Ecosystems Part Iv, R. E. Babcock, E. E. Dale, R. L. Meyer, D. G. Parker, E. G. Smith, M. D. Springer Jan 1978

Final Report Buffalo National River Ecosystems Part Iv, R. E. Babcock, E. E. Dale, R. L. Meyer, D. G. Parker, E. G. Smith, M. D. Springer

Technical Reports

Sampling point locations and analytical procedures remained unchanged from those outlined in previous Buffalo National River Ecosystem reports. The only significant change in analytical procedures was a reversion to the glass fiber filter method for collection and extraction of samples for chlorophyll analysis. This change was neeessitated by a need for filtering a larger volume to obtain enough chlorophyll for an accurate measurement. Samples were collected monthly from April 9 through December 30. No samples were taken in January or February due to the extremely uncertain traveling conditions caused by the frequent snows. Prior research indicates that the December 30 …


Water Movement Through Soil, R A. Nulsen Jan 1978

Water Movement Through Soil, R A. Nulsen

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

Even a good quality stock water moving to the surface can cause a salinity problem in only a few years.


Landform, Natural Drainage And Salinity, Eric Bettenay Jan 1978

Landform, Natural Drainage And Salinity, Eric Bettenay

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

An understanding of salt movement in streams and groundwater may lead to better methods of control and prevention of salinity.


Effects Of Surface Drainage On Dryland Salinity, P R. George, T. R. Negus Jan 1978

Effects Of Surface Drainage On Dryland Salinity, P R. George, T. R. Negus

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

Areas which are salt-affected are often also flooded. Although flooding is not the basic cause of salinity, surface drainage may improve conditions for plant growth, and this article describes suitable methods

Western Australian Soils Store Large Quantities Of Salt, C V. Malcolm, R. A. Nulsen, C. Henschke

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

Enormous quantities of salt are stored in the soil in the agricultural areas of Western Australia. Small movements in this salt can produce large effects on farms.
