    This report describes the soil and land capability study of the Lower Weaber and Keep River Plains (23,716 ha). This was a joint Commonwealth and Northern Territory project and is one of a number of parallel studies undertaken to better understand the soil and water resources within the Lower Weaber and Keep River Plains. The investigation has assessed land based constraints and determined land capability outcomes for potential future agricultural development. Section 2 of the study, which encompasses 16,929 ha of the Lower Keep River Plain has reinterpreted legacy soil data only. Pre-existing mapping in the Lower Keep was re-examined with the aid of additional landscape observations and high resolution aerial imagery. As a consequence the outcomes are of lower confidence, and convey less certainty with regard to land capability outcomes.Executive Summary; Table of Contents; 1. Introduction; 2. Methodology; 3.

    Soil and Land Suitability Assessment for Irrigated Agriculture in the Tennant Creek West Area

    No full text
    Made available by the Northern Territory Library via the Publications (Legal Deposit) Act 2004 (NT).This report describes the dominant landform, soils and vegetation of the surrounds of the Tennant Creek West Area, Northern Territory. The study area covers 578 km2 and is located approximately 50km west of the Tennant Creek township. The primary purpose of the soil and land suitability investigation was to map, describe and evaluate soil landscapes to inform future irrigation development in an area with identified potential for groundwater extraction.Report cover; Executive Summary; Table of Contents; 1.

    Elastic properties of compacted metal powders

    This paper describes a study of the unloading characteristics of compacts made from the uniaxial compression of metal powders in a cylindrical die. Spherical, irregular and dendritic copper powders and spherical stainless-steel powder were investigated to determine size, shape and material effects on the unloading response. This response was characterized in terms of Young's modulus and Poisson's ratio. Measures of these quantities were made at different relative densities by unloading from different peak axial stresses. With both parameters, there was a strong dependence on particle shape. The load response of lightly compressed material was found to be dominated by its particulate nature and interparticle forces. Unloading material in this condition gave values of Young's modulus that increased slightly and Poisson's ratio that decreased with increasing values of relative density. In contrast, the load response of heavily compressed material was found to be similar to that of a porous solid. Unloading material in this condition gave values of Young's modulus that increased more steeply and Poisson's ratio that increased with increasing values for the starting relative density. Transition between these two types of behaviour depended on the particle shape, and also, to a lesser extent, the particle material

    "Detailed soil and land capability information is critical to identify potential new agricultural areas in northern Australia. The information underpins agricultural development opportunities by providing potential investors and land managers with a high level of confidence when making investment decisions, and assists with significantly reducing the economic, social and environmental risks associated with such developments." - IntroductionExecutive summary -- Introduction -- Background information -- Methodology -- Landscapes -- Land units -- Soil -- Vegetation -- Land evaluation -- Crop suitability -- References -- Appendix 1-

    Made available by the Northern Territory Library via the Publications (Legal Deposit) Act 2004 (NT).This report describes the soil and land suitability assessment for the potential of irrigated agriculture conducted during 2016-17 for part of the Hugh River Valley within Orange Creek Station. The study area covers 16.7 km2 and is located approximately 90km south of the Alice Springs township via the Stuart Highway and the Hugh River Stock Route. The primary purpose of the investigation was to map, describe and evaluate soil landscapes to inform future irrigation development in an area with identified potential for groundwater extraction.Report cover; Executive summary; Table of Contents; 1.

    Rock cutting machine

    No full text
    A rock cutting machine including a boom (11) rotatably mounted at a proximal end to a chassis (13) adapted to be placed adjacent a rock face (14) to be cut. The boom extends from the chassis to a distal end adjacent the rock face. A longitudinal boom axis (21) extends between the proximal and the distal ends of the boom and a cutting device (10) is pivotally mounted about a pivot axis (20) adjacent the distal end of the boom. The pivot axis enables wrist movement about the pivot axis by a drive mechanism (29) and is offset from the longitudinal axis of the cutting device (23)

    This report details the land units at a mapping scale of 1:50 000 and describes the dominant landform, soils and vegetation of the the Warumungu (NT Por 502) and Kurnturlpara (NT Por 4802) Aboriginal Land Trust areas, Northern Territory. The study area covers 172km2 and is located approximately 150km east of Tennant Creek via the Barkly Highway. The primary purpose of the investigation was to map, describe and evaluate soil landscapes to inform future irrigation development in an area with identified potential for groundwater extraction. Core landform, soil and vegetation attributes are also described for each of the land units.1. Introduction -- 2. Background information -- 3. Methodology -- 4. Landscapes -- 5. Land Units -- 6.
