A Survey Of Land Suitable For Townsville Stylo In The North Kimberley Of W.A. 1973, A Kubicki, J. Beer Jan 1975

A Survey Of Land Suitable For Townsville Stylo In The North Kimberley Of W.A. 1973, A Kubicki, J. Beer

Books & book chapters

The aims of the survey were to -

(a) define the extent and actual location of country suitable for the production of non-indigenous pastures; in particular to classify the land for its suitability for Townsville stylo (Styioaanthes hurniiia).

(b) map the areas so defined on a land system basis.

The area surveyed covered approximately 88 000 sq.km (33 968 sq.miles) and included most of the catchments of the Carson, Drysdale, King Edward, Prince Regent, Charnley, Isdell and Chapman Rivers. It covered the country between latitude 14°S and 17°S and longitude 124°30'E and 127°30'E.

Analysis Of Unsteady Flow Toward Artesian Wells By Three-Dimensional Finite Elements, Yang H. Huang, Shen-Jyh Wu Aug 1974

Analysis Of Unsteady Flow Toward Artesian Wells By Three-Dimensional Finite Elements, Yang H. Huang, Shen-Jyh Wu

KWRRI Research Reports

A three-dimensional finite element computer program was developed for analyzing unsteady flow toward artesian wells. The program is designed especially for determining the drawdown around an artesian well penetrating fully or partially a nonhomogeneous and anisotropic aquifer of irregular shape and cross section. It can also be used as a general program for aquifer simulation and evaluation. A major advantage of the program lies in the minimum amount of input data required. By assuming the top and bottom boundaries of the aquifer as two arbitrary planes, the aquifer will be divided into six- or eight-node elements, and their nodal coordinates …

Chemical Quality Of The Groundwater System In Hall County, Nebraska, Jon C. Atkinson May 1973

Chemical Quality Of The Groundwater System In Hall County, Nebraska, Jon C. Atkinson

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

Hall County, an area of 540 square miles, is in south-central Nebraska. The Platte River flows east-northeasterly across the county from its southwest corner; the Wood River, which is tributary to the Platte within Hall County, enters the county about 6 miles north of the southwest corner. Analysis of streamflow data indicates that the Platte and Wood Rivers are losing streams in Hall County. Based on an 18-year period, October 1953 through September 1971, the average annual losses between gaging stations were 48,100 and 1,940 acre-feet, respectively.

The county is underlain by unconsolidated deposits of Quaternary age. These deposits mantle …

Implications Of Photogeologic Linears In The South Long Lake Area, Alpena And Presque Isle Counties, Michigan, Richard E. Kimmel Apr 1973

Implications Of Photogeologic Linears In The South Long Lake Area, Alpena And Presque Isle Counties, Michigan, Richard E. Kimmel

Masters Theses

There are numerous linear features in Alpena and Presque Isle Counties, Michigan, which are generally visible on aerial photographs. These photolinears trend in two general directions, northeast-southwest and northwest-southeast. These two sets are perpendicular to each other, and represent vector means of two fracture sets.

The development of the photolinears began in Early Devonian. Throughout its history, ground water flowed along underground channels connecting fracture intersections. This underground drainage network is responsible for many of the photolinears. Some of the photolinears can be attributed tb Early Devonian ground water activity and subsequent collapse of the Salina Salt basin, and some …


The Pierre-Niobrara Unconformity In Western Nebraska, Harold M. Degraw Jan 1973

The Pierre-Niobrara Unconformity In Western Nebraska, Harold M. Degraw

Conservation and Survey Division: Faculty and Staff Publications

The Pierre-Niobrara unconformity, one of several significant unconformities in the Cretaceous System of the Western Interior region, has not generally been recognized. Detailed correlation of electric logs of a large number of wells in western Nebraska provides evidence of its existence. Isopach maps of the beds occupying three identifiable stratigraphic intervals - a redefined Niobrara Formation, an unnamed uppermost Niobrara unit, and an unnamed basal Pierre unit, which includes the Ardmore Bentonite - provide recognizable geologic patterns that permit reconstruction of the stages of development of the unconformity. The upper part of the Niobrara Formation has been truncated in several …
